Abstract
PURPOSE This study aims to identify and describe factors that influence hearing aid outcomes including social networks, self-reported mental health, and service delivery models. METHOD A prospective cross-sectional online survey was sent to hearing aid users recruited through an online platform (http://www.hearingtracker.com) between October and November 2021. The survey contained questions on patient demographics, audiological variables, general health and social factors, and self-reported hearing aid outcomes using the International Outcome Inventory for Hearing Aids (IOI-HA). Regression models evaluated potential contributing factors of hearing aid outcomes on the IOI-HA. RESULTS Three hundred ninety-eight hearing aid users completed the survey with an average age of 66.6 (SD = 13.0) years, of which 59.3% were male. Positive contributing factors of hearing aid outcomes (IOI-HA total score) were social network of people with hearing loss with hearing aids (p < .010; Exp[B] = 0.03, 95% CI [0.01, 0.1]), self-reported mental health (p < .05; Exp[B] = 0.6, 95% CI [0.01, 1.2]), work situation (p < .001; Exp[B] = 1.9, 95% CI [0.7, 2.8]), quality of life (p < .005; Exp[B] = 1.2, 95% CI [0.3, 1.1]), and self-reported hearing difficulty (p < .02; Exp[B] = 0.8, 95% CI [0.2, 1.5]). Negative contributing factors of hearing aid outcomes included social networks of people with hearing loss without hearing aids (p < .001; Exp[B] = -0.1, 95% CI [-0.2, -0.2]) and service delivery model of private or university clinic compared to big-box retailers (p < .001; Exp[B] = -1.6, 95% CI [-2.7, -0.7]). CONCLUSIONS Novel factors including social network of persons with hearing loss who use hearing aids, self-reported mental health, service delivery model, and work situation are significant contributors to hearing aid outcomes. These newly identified factors can inform public hearing health promotion and individualized audiological care to optimize hearing aid outcomes.

Abstract
OBJECTIVE Although many speech enhancement (SE) algorithms have been proposed to promote speech perception in hearing-impaired patients, the conventional SE approaches that perform well under quiet and/or stationary noises fail under nonstationary noises and/or when the speaker is at a considerable distance. Therefore, the objective of this study is to overcome the limitations of the conventional speech enhancement approaches. METHOD This study proposes a speaker-closed deep learning-based SE method together with an optical microphone to acquire and enhance the speech of a target speaker. RESULTS The objective evaluation scores achieved by the proposed method outperformed the baseline methods by a margin of 0.21-0.27 and 0.34-0.64 in speech quality (HASQI) and speech comprehension/intelligibility (HASPI), respectively, for seven typical hearing loss types. CONCLUSION The results suggest that the proposed method can enhance speech perception by cutting off noise from speech signals and mitigating interference caused by distance. SIGNIFICANCE The results of this study show a potential way that can help improve the listening experience in enhancing speech quality and speech comprehension/intelligibility for hearing-impaired people.

Evaluation of auditory brainstem implant (ABI) users' auditory behavior in everyday life. Eur Arch Otorhinolaryngol 2023; 280:5299-5305. [PMID: 37272952 DOI: 10.1007/s00405-023-08046-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 05/26/2023] [Indexed: 06/06/2023]
Abstract
PURPOSE This study aims to evaluate the everyday listening status of pediatric ABI users using the Turkish ABEL questionnaire. METHODS The study included 33 parents of children with auditory brainstem implant, and 28 parents of children with cochlear implant were included as a control group. All implant users were between the ages of 4-14. Parents answered the ABEL questionnaire to assess their child's auditory behavior in their daily living environment. In addition, Categories of Auditory Performance (CAP) and Speech Intelligibility Rating (SIR) scales were used to evaluate speech perception and production. RESULTS Auditory-aural, auditory awareness and ABEL total score of ABI users were statistically significantly lower than the CI group (p < 0.05). There was no statistically significant difference between the groups in the Conversational/Social skills subgroups. It was found that as the duration of ABI use increased, auditory-verbal, social skills and total scores increased significantly. In addition, correlations were obtained between ABEL total and subscale scores and CAP and SIR scores. CONCLUSIONS Parents believe that their children adapt nicely to ABI and are aware of environmental sounds. This study reveals the auditory, aural, and social skills of children using ABI through the regards of their parents. This study showed that the ABEL questionnaire, which was used in previous studies to express parental views of children with hearing aids and cochlear implants, can also be used for parents of children using ABI.

Abstract
BACKGROUND For severe hearing loss and even profound deafness, cochlear implants (CIs) have become the treatment of choice. For establishment of the CI indication, the preoperative Freiburger monosyllabic word recognition (EV) at 65 dB SPL in free field with a hearing aid (EVHG65) and the maximal understanding (mEV) without a hearing aid with headphones results are important. The goal of this retrospective study was to analyse the correlation of word recognition with a hearing aid at 80 dB SPL (EVHG80) and mEV. This represents an extension to measuring EVHG65 compared to mEV and to pure-tone audiometry (4FPTA). METHODS In this study, word recognition with and without a hearing aid was retrospectively analysed for 661 ears. Inclusion criterium was CI implantation at a later date. RESULTS During preoperative CI diagnostics, an mEV of 0% was found in 334 ears. The EVHG65 for 485 ears and the EVHG80 for 335 ears were also 0%. The EV with hearing aid was found to worsen with increasing 4FPTA at both sound pressure levels, although this effect was smaller at 80 dB SPL than at 65 dB SPL. Including only ears with mEV > 0 % (N = 260 ears), a stronger correlation between EVHG80 and mEV with a difference of (-4.0 ± 16.4%) in comparison to EVHG65 and mEV with a difference of (-18.3 ± 16.7%) is seen. This shows a significant difference between mEV and EVHG80 compared to mEV and EVHG65. CONCLUSION At a sound pressure level of 65 dB SPL, EV with hearing aid often does not show the accordance with mEV specified by hearing aid and CI guidelines. The EVHG80 correlates better with mEV than EVHG65. For clinical diagnosis it is rational to measure speech discrimination with hearing aid at levels higher than 65 dB SPL.

Abstract
OBJECTIVE This study aimed to examine the status of the supply system for hearing aids at stores in Japan. METHODS This was a cross-sectional, observational study. We mailed questionnaires to 4502 hearing aid stores in Japan and analyzed the responses. RESULTS Of the 4502 stores, 1032 (23%) responded. Most stores accessed audiogram information and adjusted hearing aids using computer fitting software. Overall, 43% of the stores only used the manufacturer's original prescription formula to adjust the hearing aid, and 47% of stores lacked a device for measuring the frequency response of the hearing aids. Moreover, 20% of the stores lacked both a sound field threshold measurement system and a real-ear measurement device. Objective evaluations, including functional gain, rear-ear insertion gain, and frequency response data, were not performed by 14% stores. Speech-language-hearing therapists were present in only 5.6% stores. CONCLUSION The findings revealed several key shortcomings in the hearing aid supply system at hearing aid stores in Japan.

Bone-anchored hearing aids: Percutaneous versus transcutaneous attachments - a health economics comparison in paediatric patients. Int J Pediatr Otorhinolaryngol 2023; 175:111773. [PMID: 37931497 DOI: 10.1016/j.ijporl.2023.111773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Revised: 10/07/2023] [Accepted: 10/30/2023] [Indexed: 11/08/2023]
Abstract
INTRODUCTION Bone anchored hearing aids (BAHA) are a useful support when conventional hearing aids are not suitable. The two types of attachment of the aid are onto a percutaneous abutment or a transcutaneous magnet. Anecdotally, the abutment requires more care, revision procedures and causes more infections than magnet-based devices. METHODS A multicentre, retrospective review was conducted of all patients that underwent a BAHA since our programme began, identified through a prospectively maintained database of patients. Patients' charts were audited for outpatient clinic visits, skin complications and revision surgeries. Developmental delay was also recorded. Patients were censored if the hearing aid was removed, replaced or the patient reached 16 years old. Bilateral or reimplanted patients were recorded as separate implants. Statistical analysis was performed using SAS version 9.4. RESULTS 150 implants were assessed over 126 patients: 115 transcutaneous and 35 percutaneous. Percutaneous patients had significantly more outpatient clinic attendances (Least square mean 4.19 vs. 1.39 p = 0.00), skin complications (mean 4.82 v 0.11 p = 0.00) and theatre visits (mean 2.8 vs. 1.03 p = 0.00) compared to transcutaneous patients. 77 implants were in patients that had developmental delay; having same made no significant difference to above outcomes. CONCLUSION There is a significant difference in healthcare burden between percutaneous and transcutaneous systems in a paediatric population. The increased cost of the percutaneous implant to the healthcare system and inconvenience to the patient is cause to consider a transcutaneous system in the first instance.

Abstract
Recent Food and Drug Administration approval of over-the-counter (OTC) hearing aids has changed the policy landscape surrounding hearing-assistive technology. Our objective was to characterize trends in information-seeking behavior in the era of OTC hearing aids. Using Google Trends, we extracted the relative search volume (RSV) for hearing health-related topics. The mean RSV in the 2 weeks preceding and following enactment of the FDA's OTC hearing aid ruling were compared using a paired samples t-test. RSV for hearing-related queries increased by 212.5% on the date of FDA approval. There was a 25.6% (p = .02) increase in mean RSV for "hearing aids" before and after the FDA ruling. The most popular searches focused on specific device brands and cost. States with more rural residents represented the highest proportion of queries. Understanding these trends is critical to ensure appropriate patient counseling and improve access to hearing assistive technology.

Effects of entropy in real-world noise on speech perception in listeners with normal hearing and hearing lossa). THE JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA 2023; 154:3627-3643.

Abstract
Hearing aids show more benefit in traditional laboratory speech-in-noise tests than in real-world noisy environments. Real-world noise comprises a large range of acoustic properties that vary randomly and rapidly between and within environments, making quantifying real-world noise and using it in experiments and clinical tests challenging. One approach is to use acoustic features and statistics to quantify acoustic properties of real-world noise and control for them or measure their relationship to listening performance. In this study, the complexity of real-world noise from different environments was quantified using entropy in both the time- and frequency-domains. A distribution of noise segments from low to high entropy were extracted. Using a trial-by-trial design, listeners with normal hearing and hearing loss (in aided and unaided conditions) repeated back sentences embedded in these noise segments. Entropy significantly affected speech perception, with a larger effect of entropy in the time-domain than the frequency-domain, a larger effect for listeners with normal hearing than for listeners with hearing loss, and a larger effect for listeners with hearing loss in the aided than unaided condition. Speech perception also differed between most environment types. Combining entropy with the environment type improved predictions of speech perception above the environment type alone.

Abstract
Assistive auditory devices that enhance signal-to-noise ratio must follow the user's changing attention; errors could lead to the desired source being suppressed as noise. A method for measuring the practical benefit of attention-following speech enhancement is described and used to show a benefit for gaze-directed beamforming over natural binaural hearing. First, participants watched a recorded video conference call between two people with six additional interfering voices in different directions. The directions of the target voices corresponded to the spatial layout of their video streams. A simulated beamformer was yoked to the participant's gaze direction using an eye tracker. For the control condition, all eight voices were spatially distributed in a simulation of unaided binaural hearing. Participants completed questionnaires on the content of the conversation, scoring twice as high in the questionnaires for the beamforming condition. Sentence-by-sentence intelligibility was then measured using new participants who viewed the same audiovisual stimulus for each isolated sentence. Participants recognized twice as many words in the beamforming condition. The results demonstrate the potential practical benefit of gaze-directed beamforming for hearing aids and illustrate how detailed intelligibility data can be retrieved from an experiment that involves behavioral engagement in an ongoing listening task.

Abstract
OBJECTIVE Hearing aids (HAs) are designed for speech rather than music listening. The impact of HAs on music enjoyment is poorly studied. We examine the effect of HAs on active music enjoyment in individuals with varying levels of hearing loss (HL). STUDY DESIGN Cross-sectional study. SETTING Tertiary medical center and community. METHODS Adult (≥18 years) bilateral HA users and normal hearing (NH) controls actively listened to musical stimuli and rated their enjoyment across 3 measures (pleasantness, musicality, naturalness) with and without HAs using a visual analog scale. Multivariable linear regression was used to assess the association between HL (measured by a pure-tone average [PTA] and word recognition score [WRS] of the better ear) and music enjoyment with and without HAs, adjusting for covariates. Music enjoyment was compared between HA users and NH controls, and HA users with and without their HAs. RESULTS One hundred bilateral HA users (mean age 66.0 years, 52% female, better ear mean [SD] PTA 50.2 [13.5] dBHL, mean WRS 84.5 [16.5]%) completed the study. Increasing severity of HL (PTA) was independently associated with decreased music enjoyment (pleasantness, musicality, naturalness) with and without HAs (p < .05). HA usage increased music enjoyment (musicality) in those with moderate to moderately severe HL. Music enjoyment in NH controls (n = 20) was significantly greater across all measures compared to HA users. CONCLUSION Increased severity of HL is associated with decreased music enjoyment that can be enhanced with HA usage. Thus, HA usage can positively enhance both speech and music appreciation.

Abstract
INTRODUCTION Bone-conduction hearing device (BCHD) uses natural sound transmission through bone and soft tissue, directly to the cochlea, via an external processor that captures and processes sound, which is converted into mechanical vibrations. Key parameters, as maximum power output (MPO) and broader frequency range (FR), must be considered when indicating a BCHD because they can be decisive for speech recognition, especially under listening challenge conditions. OBJECTIVES Compare hearing performance and speech recognition in noise of two sound processors (SPs), with different features of MPO and FR, among BCHD users. MATERIALS AND METHODS This single-blinded, comparative, observational study evaluated 21 individuals Baha 4 system users with conductive or mixed hearing impairment. The free-field audiometry and speech recognition results were blindly collected under the following conditions: unaided, with Baha 5, and with Baha 6 Max SP. RESULTS In free-field audiometry, significant differences were observed between the SP at 0.25, 3, 4, 6, and 8 kHz, with Baha 6 Max outperforming Baha 5. The Baha 6 Max provided significantly better speech recognition than Baha 5 under all the speech in noise conditions evaluated. Separating the transcutaneous from the percutaneous users, Baha 6 Max Attract SP provided the best results and significantly lowered the free-field thresholds than Baha 5 Attract. The Baha 6 Max also significantly improved speech recognition in noise, among both Attract and Connect users. CONCLUSION The present study revealed that the greater MPO and broader FR of the Baha 6 Max device helped increase high-frequency gain and improved speech recognition in BCHD-experimented users.

Abstract
OBJECTIVE Limited evidence to date has examined public perceptions of cochlear implants among adult hearing aid users with moderate to profound hearing loss. The current work was conceived with the chief objective of characterizing the perceptions surrounding cochlear implants among the prospective candidate pool. STUDY DESIGN National cross-sectional survey study. SETTING United States. PATIENTS Adults between 50 and 80 years of age with self-reported moderate to moderately severe (n = 200) or moderately severe to profound (n = 200) hearing loss currently using hearing aids. RESULTS The overall survey response rate was 12%. Median age at time of survey for the 400 respondents was 66 years (interquartile range, 60-71 yr) and included 215 (54%) men. In total, 26% did not think of hearing loss as a medical condition, and another 23% were unsure. Overall, 63% of respondents had heard of cochlear implants, but only 2% indicated they were very familiar with them. Despite 52% of respondents reporting "very positive" or "somewhat positive" feelings about cochlear implants, only 9% indicated they were "very likely" to get a cochlear implant in the future, including 7% of those with estimated moderately severe to profound hearing loss at time of survey. CONCLUSIONS Even among people with presumed qualifying levels of hearing loss, there exists a widespread lack of familiarity with cochlear implantation as a viable treatment option. This limited awareness seems influenced by a generally poor appreciation for hearing loss as a chronic disease state that warrants treatment. However, among those familiar with cochlear implants, they are generally viewed favorably.

Abstract
OBJECTIVE To determine if hearing aid use in school aged children is impacted when upgraded to direct Bluetooth® enabled technology. We hypothesized that because children are better able to connect to their devices and headphones, they would be more inclined to use their hearing aids throughout the day, resulting in an increase in hearing aid compliance. METHODS This retrospective analysis examined changes in datalogging of hours of usage per day in 51 school aged children who underwent an upgrade from non-direct Bluetooth® hearing technology to direct Bluetooth®-enabled hearing technology. RESULTS Hours per day of hearing aid use in all hearing aid users significantly increased after upgrading to DBT enabled technology (6.82 vs 9.82, <0.001). There were no significant differences noted in hours before and after upgrade depending on race (p = 0.147), gender (p = 0.887), developmental delay (p = 0.749), type of hearing loss (p = 0.218), and degree of hearing loss (p = 0.551). However, when comparing private versus Medicaid insurance, there was noted to be a significant difference with the odds of an increase in hours of usage after upgrade being higher for those patients privately insured (OR = 1.247, p < 0.001, 95 % CI 1.093-1.422). CONCLUSION Direct Bluetooth® enabled hearing technology positively impacts children's hearing aid compliance, which has the potential improve speech and language outcomes.

Applying the reference values of real-ear-to-coupler-difference for deaf and hard-of-hearing children in Taiwan: Cautions and considerations. PLoS One 2023; 18:e0295236.

Abstract
Measurement of real-ear-to-coupler differentials (RECDs) is a critical part of the hearing aid (HA) verification process. This study examines the validity of reference RECD values preset by the HA analyzer, Audioscan RM500, for deaf-and-hard-of-hearing (DHH) children in Taiwan. RECD measurements were performed on 658 ears of DHH children. A linear mixed model was used to analyze the reference and measured RECD values. The findings revealed slight disparities between normative RECD values from North America and those observed in Taiwanese DHH children. While generally small (less than 5 dB), these differences imply potential challenges in achieving optimal HA fitting in specific scenarios. Therefore, we recommend individualized RECD/REM measurements for cases of poor auditory performance, certain frequency ranges, or notable variations in ear canal volume. From a clinical perspective, while broadly applicable, the use of North American RECD normative data in Taiwan requires cautious consideration of potential minor variations. This study contributes to current knowledge by affirming the use of a Western RECD database for Taiwanese DHH children. However, we underscore the ongoing importance of individualized HA fitting strategies, particularly for cases with stagnant intervention progress. While built-in RECD reference values can offer preliminary fitting guidance, especially in busy clinical settings, our study sheds light on the circumstances where caution is essential. Audiologists can efficiently allocate their time and effort by focusing on personalized RECD measurements for cases exhibiting suboptimal intervention outcomes, thereby effectively optimizing HA gain settings.

Abstract
INTRODUCTION The prevalence of hearing loss in Canada is high, with many patients requiring implantable hearing devices (IHDs) as treatment for their disease severity. Despite this need, many eligible patients do not pursue these interventions. The objective of this study was to examine rates of IHD based on geographic location to understand locoregional variation in access to care. STUDY DESIGN This was a retrospective population-based cohort study. SETTING All hospitals in the Canadian province of Ontario. METHODS Of all patients with IHD between April 1, 1992, and March 31, 2021, cochlear implants (CIs) (4,720) and bone-anchored hearing aids (BAHA) (1,125) cohorts were constructed. Place of residence was categorized based on Local Health Integrated Network (LHIN). Summary statistics for place of surgical institution based on LHIN at first surgery, name of institution of first surgery and "as the crow flies" distance (in km) between place of residence and surgical institution were calculated. Rate of implantations was calculated for LHIN regions based on number of surgeries per 1,000,000 persons/years. RESULTS Toronto Central, Central, Central East, and Champlain regions had >10% of patients undergoing BAHA and CI. 1,019 (90.6%) and 4,232 (89.7%) of patients receiving BAHA and CI, respectively, resided in urban/suburban regions and 94 patients (8.4%) and 436 (9.2%) resided in rural regions. The median distance between residential location and the institution was 46.4 km (interquartile range [IQR], 18.9-103.6) and 44.7 km (IQR, 15.7-96.9) for BAHA and CI, respectively. From 1992 to 2021, the number of CI and BAHA performed across Ontario increased by 17 folds and 6 folds, respectively. CONCLUSION This large comprehensive population study provides longitudinal insight into the access to care of IHD based on geographic factors. Our findings of the present population-based study indicate an overall increase in access to devices with disproportionate access to care based on geographic locations. Further work is needed to characterize barriers to IHD access to align with demands.

[PMID: 37870877 PMCID: PMC10721240 DOI: 10.1044/2023_jslhr-22-00720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 05/09/2023] [Accepted: 08/14/2023] [Indexed: 10/24/2023]
Abstract
OBJECTIVES The purposes of this study were to compare (a) listening-in-noise (accuracy and effort) and (b) remote microphone (RM) system benefits between autistic and non-autistic youth. DESIGN Groups of autistic and non-autistic youth that were matched on chronological age and biological sex completed listening-in-noise testing when wearing and not wearing an RM system. Listening-in-noise accuracy and listening effort were evaluated simultaneously using a dual-task paradigm for stimuli varying in type (syllables, words, sentences, and passages). Several putative moderators of RM system effects on outcomes of interest were also evaluated. RESULTS Autistic youth outperformed non-autistic youth in some conditions on listening-in-noise accuracy; listening effort between the two groups was not significantly different. RM system use resulted in listening-in-noise accuracy improvements that were nonsignificantly different across groups. Benefits of listening-in-noise accuracy were all large in magnitude. RM system use did not have an effect on listening effort for either group. None of the putative moderators yielded effects of the RM system on listening-in-noise accuracy or effort for non-autistic youth that were significant and interpretable, indicating that RM system benefits did not vary according to any of the participant characteristics assessed. CONCLUSIONS Contrary to expectations, autistic youth did not demonstrate listening-in-noise deficits compared to non-autistic youth. Both autistic and non-autistic youth appear to experience RM system benefits marked by large gains in listening-in-noise performance. Thus, the use of this technology in educational and other noisy settings where speech perception needs enhancement might be beneficial for both groups of children.

Production of Tone 2 in disyllabic words in Mandarin Chinese speaking children aged 3-5 with a cochlear implant and a contralateral hearing aid. CLINICAL LINGUISTICS & PHONETICS 2023; 37:1013-1029. [PMID: 36214108 DOI: 10.1080/02699206.2022.2126332] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 09/07/2022] [Accepted: 09/13/2022] [Indexed: 06/16/2023]
Abstract
To investigate Mandarin Tone 2 production of disyllabic words of prelingually deafened children with a cochlear implant (CI) and a contralateral hearing aid (HA) and to evaluate the relationship between their demographic variables and tone-production ability. Thirty prelingually Mandarin-speaking preschoolers with CI+HA and 30 age-matched normal-hearing (NH) children participated in the study. Fourteen disyllabic words were recorded from each child. A total of 840 tokens (14 × 60) were then used in tone-perception tests in which four speech therapists participated. The production of T2-related disyllabic words of the bimodal group was significantly worse than that of the NH group, as reflected in the overall accuracy (88.57% ± 16.31% vs 99.29% ± 21.79%, p < 0.05), the accuracy of T1+T2 (93.33% vs 100%), the accuracy of T2+T1 (66.67 ± 37.91% vs 98.33 ± 9.13%), and the accuracy of T2+T4 (78.33 ± 33.95% vs 100%). In addition, the bimodal group showed significantly inferior production accuracy of T2+T1 than T2+T2 and T3+T2, p < 0.05. Both bimodal age and implantation age were significantly negatively correlated with the overall production accuracy, p < 0.05. For the error patterns, bimodal participants experienced more errors when T2 was in the first position of the tone combination, and T2 was most likely to be mispronounced as T1 and T3. Bimodal patients aged 3-5 have T2-related disyllabic lexical tone production defects, and their performances are related to tone combination, implantation age, and bimodal age.

Abstract
OBJECTIVE A long-standing observation is that the Mismatch Response (MMR) has the potential to offer a clinically feasible index of sound discrimination. However, findings that positively identify MMRs at the individual level have been mixed, even for those who are normally hearing and who can discriminate sounds behaviourally. This complicates interpretation when an MMR is not observed. The objective of this study was to determine the reliability of the MMR using an optimised paradigm and a range of stimuli relevant to audiological applications in relation to objective verification of hearing aid fittings. DESIGN MMRs were measured using an optimised 3-deviant paradigm in response to a range of sounds designed for aided and unaided sound field assessments, including complex tones (CTs) and speech-like signals. STUDY SAMPLE Seventeen normally hearing adults (18-56 years). RESULTS The most robust MMRs were recorded in response to CTs; responses were positively identified in 50 out of 51 instances (98%), assessed via objective Hotelling's T2 bias-free statistical analyses. CONCLUSIONS The results indicate that CTs in conjunction with optimised recording and analysis parameters offer the potential to elicit robust MMRs, supporting future utilisation of MMRs for clinical audiological applications.

Abstract
OBJECTIVE Individuals who are deaf or hard of hearing (DHH) may find adherence to their hearing devices difficult due to internal experiences related to their hearing loss such as sadness or frustration. The Acceptance and Action Questionnaire-Adult Hearing Loss (AAQ-AHL) is the only measure available to assess psychological inflexibility as it relates to hearing loss. The purpose of this study was to confirm the single latent structure of the AAQ-AHL (through confirmatory factory analysis) and test convergent and discriminant validity. DESIGN Cross-sectional data was used to further validate the AAQ-AHL. STUDY SAMPLE Participants were 146 adults who had diagnosed hearing loss and used a hearing aid. RESULTS Results revealed the AAQ-AHL has a single latent structure, correlated to other similar constructs (psychological flexibility and hearing aid efficacy), and not correlated to unrelated constructs (hearing loss severity). These results suggest that the AAQ-AHL is a valid instrument to assess psychological flexibility as it relates to hearing aid use. CONCLUSION Together, the findings imply the AAQ-AHL has strong psychometric properties and justification to use in a clinical setting.

Abstract
OBJECTIVE Hearing loss commonly causes difficulties in understanding speech in the presence of background noise. The benefits of hearing-aids in terms of speech intelligibility in challenging listening scenarios remain limited. The present study investigated if phoneme-in-noise discrimination training improves phoneme identification and sentence intelligibility in noise in hearing-aid users. DESIGN Two groups of participants received either a two-week training program or a control intervention. Three phoneme categories were trained: onset consonants (C1), vowels (V) and post-vowel consonants (C2) in C1-V-C2-/i/ logatomes from the Danish nonsense word corpus (DANOK). Phoneme identification test and hearing in noise test (HINT) were administered before and after the respective interventions and, for the training group only, after three months. STUDY SAMPLE Twenty 63-to-79 years old individuals with a mild-to-moderate sensorineural hearing loss and at least one year of experience using hearing-aids. RESULTS The training provided an improvement in phoneme identification scores for vowels and post-vowel consonants, which was retained over three months. No significant performance improvement in HINT was found. CONCLUSION The study demonstrates that the training induced a robust refinement of auditory perception at a phoneme level but provides no evidence for the generalisation to an untrained sentence intelligibility task.

Exploring Factors That Contribute to the Success of Rehabilitation With Hearing Aids. Ear Hear 2023; 44:1514-1525.

Abstract
OBJECTIVES Hearing aids are an essential and important part of hearing rehabilitation. The combination of technical data on hearing aids and individual rehabilitation needs can give insight into the factors that contribute to the success of rehabilitation. This study sets out to investigate if different subgroups of (comparable) hearing aids lead to differences in the success of rehabilitation, and whether these differences vary between different domains of auditory functioning. DESIGN This study explored the advantages of including patient-reported outcome measures (PROMs) in the process of purchasing new hearing aids in a large sample of successful hearing aid users. Subject data were obtained from 64 (commercial) hearing aid dispensers and 10 (noncommercial) audiological centers in the Netherlands. The PROM was a 32-item questionnaire and was used to determine the success of rehabilitation using hearing aids by measuring auditory disability over time. The items were mapped on six domains of auditory functioning: detection, discrimination, localization, speech in quiet, speech in noise, and noise tolerance, encompassing a variety of daily-life listening situations. Hearing aids were grouped by means of cluster analysis, resulting in nine subgroups. In total, 1149 subjects were included in this study. A general linear model was used to model the final PROM results. Model results were analyzed via a multifactor Analysis of Variance. Post hoc analyses provided detailed information on model variables. RESULTS Results showed a strong statistically significant effect of hearing aids on self-perceived auditory functioning in general. Clinically relevant differences were found for auditory domains including detection, speech in quiet, speech in noise, and localization. There was only a small, but significant, effect of the different subgroups of hearing aids on the final PROM results, where no differences were found between the auditory domains. Minor differences were found between results obtained in commercial and noncommercial settings, or between novice and experienced users. Severity of Hearing loss, age, gender, and hearing aid style (i.e., behind-the-ear versus receiver-in-canal type) did not have a clinically relevant effect on the final PROM results. CONCLUSIONS The use of hearing aids has a large positive effect on self-perceived auditory functioning. There was however no salient effect of the different subgroups of hearing aids on the final PROM results, indicating that technical properties of hearing aids only play a limited role in this respect. This study challenges the belief that premium devices outperform basic ones, highlighting the need for personalized rehabilitation strategies and the importance of evaluating factors contributing to successful rehabilitation for clinical practice.

Neural envelope tracking predicts speech intelligibility and hearing aid benefit in children with hearing loss. Hear Res 2023; 439:108893. [PMID: 37806102 DOI: 10.1016/j.heares.2023.108893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 09/01/2023] [Accepted: 09/27/2023] [Indexed: 10/10/2023]
Abstract
Early assessment of hearing aid benefit is crucial, as the extent to which hearing aids provide audible speech information predicts speech and language outcomes. A growing body of research has proposed neural envelope tracking as an objective measure of speech intelligibility, particularly for individuals unable to provide reliable behavioral feedback. However, its potential for evaluating speech intelligibility and hearing aid benefit in children with hearing loss remains unexplored. In this study, we investigated neural envelope tracking in children with permanent hearing loss through two separate experiments. EEG data were recorded while children listened to age-appropriate stories (Experiment 1) or an animated movie (Experiment 2) under aided and unaided conditions (using personal hearing aids) at multiple stimulus intensities. Neural envelope tracking was evaluated using a linear decoder reconstructing the speech envelope from the EEG in the delta band (0.5-4 Hz). Additionally, we calculated temporal response functions (TRFs) to investigate the spatio-temporal dynamics of the response. In both experiments, neural tracking increased with increasing stimulus intensity, but only in the unaided condition. In the aided condition, neural tracking remained stable across a wide range of intensities, as long as speech intelligibility was maintained. Similarly, TRF amplitudes increased with increasing stimulus intensity in the unaided condition, while in the aided condition significant differences were found in TRF latency rather than TRF amplitude. This suggests that decreasing stimulus intensity does not necessarily impact neural tracking. Furthermore, the use of personal hearing aids significantly enhanced neural envelope tracking, particularly in challenging speech conditions that would be inaudible when unaided. Finally, we found a strong correlation between neural envelope tracking and behaviorally measured speech intelligibility for both narrated stories (Experiment 1) and movie stimuli (Experiment 2). Altogether, these findings indicate that neural envelope tracking could be a valuable tool for predicting speech intelligibility benefits derived from personal hearing aids in hearing-impaired children. Incorporating narrated stories or engaging movies expands the accessibility of these methods even in clinical settings, offering new avenues for using objective speech measures to guide pediatric audiology decision-making.

Abstract
BACKGROUND The aim of this study is to investigate the deviced and non-deviced auditory performance results of patients with unilateral bone-anchored hearing aid. METHODS Deviced and non-deviced free field hearing thresholds, speech discrimination, and sentence discrimination scores were evaluated. Shortened profile of the benefit from the hearing instrument (Abbreviated Profile of Hearing Aid Benefit) was used. RESULTS A total of 17 patients participated in the study. The mean age was 37.9 ± 17.1 years. There was a statistically significant difference between the Abbreviated Profile of Hearing Aid Benefit satisfaction questionnaire and total scores, Background Noise (BN), Reverberation (RV) subscales according to device status (P -lt; .05). No significant difference was found between the Abbreviated Profile of Hearing Aid Benefit total score result of the group divided by the hearing aid threshold (P -gt; .05). No significant difference was found between the Abbreviated Profile of Hearing Aid Benefit total score result of the group divided by the threshold without a hearing aid (P -gt; .05). CONCLUSION Bone-implanted hearing aids are effective and reliable amplification methods in patients with conductive and mixed hearing loss. Positive results of patient satisfaction and evaluation inventories were obtained from this study.

Abstract
OBJECTIVES To conduct a systematic review to address the following research questions: Q1. Does wireless binaural beamforming technology perform better than conventional microphone technologies in improving the speech perception in noise abilities of individuals with hearing aids bilaterally? and Q2. Do the subjective rating scores of hearing aid benefits suggest that wireless binaural beamforming technology is better than other microphone technologies? DESIGN Two independent authors performed a comprehensive search utilizing electronic databases like PubMed, Embase, Web of Science, and Scopus. Aside from these databases, course transcripts, white papers, evidence, and field study articles from various manufacturer websites were also included. The certainty of the evidence for each outcome was determined using Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guidelines. RESULTS Eleven studies were included for the qualitative synthesis. The available data were categorized into three groups (bilateral omnidirectional, bilateral directional, and bilateral asymmetric directional microphone processing) and compared against wireless binaural beamformers. The results of the Sign test revealed that for Q1, the wireless binaural beamformer significantly outperformed the bilateral omnidirectional microphone processing. However, no significant differences were observed when compared with other groups. Results for Q2 showed no significant improvement in wireless binaural beamformers compared to other groups. CONCLUSION The superior performance of the wireless binaural beamformers over conventional microphone technologies was demonstrated by the speech perception in noise tasks but not by the self-reported subjective ratings. Nevertheless, the evidence for both speech perception noise and subjective ratings was weak.

Abstract
The incidence of single-sided deafness(SSD) is increasing year by year. Due to the hearing defects of one ear, the ability of sound localization, speech recognition in noise, and quality of life of patients with single-sided deafness will be affected to varying degrees. This article reviews the intervention effects of different types of bone conduction hearing aids in patients with single-sided deafness and asymmetric hearing loss, and the differences of intervention effects between bone conduction hearing aids, contralateral routing of signal(CROS) aids, and cochlea implant(CI), to provide a reference for the auditory intervention and clinical treatment of single-sided deafness and asymmetric hearing loss.

Abstract
Background: No selection criteria for the four bone conduction hearing devices yet.Aims/Objectives: To compare effectiveness of four bone conduction hearing devices in patients with bilateral Congenital Malformation of the Middle and Outer Ear (CMMOE).Material and Methods: 24 Patients (25 ears) were divided into five groups: 1) Bone Anchored Hearing Aid softband (BAHA-s), 2) BAHA implant (BAHA-i nested within group 1), 3) Vibration Sound Bridge implant (VSB-i), 4) Bone Bridge implant (BB-i), and 5) Bone Conduction Hearing Aid softband (BCHA-s). One patient implanted VSB and BB. Auditory parameters were compared: 1. Communication, 2. Average Air Conduction Thresholds (ACT) of pure tone, 3. Sentence Recognition Scores in quiet (SRS-q) and noisy (SRS-n) settings. The one-way analysis of variance (ANOVA) were employed to compare the differences in ACT and SRS-q/n among the groups, a statistical significance level of P < 0.05 was applied.Results: After hearing aid usage, all 24 patients (25 ears) reached or approached the normal in communication (i.e. from difficult to smooth), average ACT and SRS-q/SRS-n (no difference among groups, p > 0 .05). However, there was the difference in the optimal frequency of ACT and the absolute value of SRS-q/SRS-n for VSB/BAHA implants was higher than that for BB and BAHA softband.Conclusions and Significance: The precise selection of the four hearing devices mainly depends on patient's hearing level, the optimal frequency of ACT and absolute values of SRS-q/SRS-n.

Abstract
PURPOSE Longitudinally verify the influence of auditory tonal thresholds obtained with transcutaneous and percutaneous bone-anchored hearing aids on speech perception in individuals with external and/or middle ear malformation and chronic otitis media. METHODS Observational, retrospective, longitudinal follow-up study of 30 unilateral users of the transcutaneous and percutaneous Baha® system for the collection of secondary data on pure tone thresholds obtained through free field audiometry and sentence recognition threshold in silence and noise in conditions: without the prosthesis; at the time of activation; in the first month of use (post 1); and in the third month (post 2). RESULTS There was a significant difference between pure tone thresholds obtained at frequencies of 3 and 4kHz with better results for the percutaneous technique at all evaluation moments. For both systems, better performance was observed in sentence recognition in silence and in noise, with a significant difference in activation (p<0.001), but it remained stable during the other evaluation moments. The percutaneous system showed better benefit in recognizing sentences in noise only on activation (p=0.036), when compared to the transcutaneous system. CONCLUSION The percutaneous system provided better audibility for high frequencies; however, such audibility did not influence sentence recognition in the silent situation for both systems. For the noise situation, better responses were observed in the percutaneous system, however, the difference was not maintained over time.

At-home computerized executive-function training to improve cognition and mobility in normal-hearing adults and older hearing aid users: a multi-centre, single-blinded randomized controlled trial. BMC Neurol 2023; 23:378. [PMID: 37864139 PMCID: PMC10588173 DOI: 10.1186/s12883-023-03405-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 09/26/2023] [Indexed: 10/22/2023] Open
Abstract
BACKGROUND Hearing loss predicts cognitive decline and falls risk. It has been argued that degraded hearing makes listening effortful, causing competition for higher-level cognitive resources needed for secondary cognitive or motor tasks. Therefore, executive function training has the potential to improve cognitive performance, in turn improving mobility, especially when older adults with hearing loss are engaged in effortful listening. Moreover, research using mobile neuroimaging and ecologically valid measures of cognition and mobility in this population is limited. The objective of this research is to examine the effect of at-home cognitive training on dual-task performance using laboratory and simulated real-world conditions in normal-hearing adults and older hearing aid users. We hypothesize that executive function training will lead to greater improvements in cognitive-motor dual-task performance compared to a wait-list control group. We also hypothesize that executive function training will lead to the largest dual-task improvements in older hearing aid users, followed by normal-hearing older adults, and then middle-aged adults. METHODS A multi-site (Concordia University and KITE-Toronto Rehabilitation Institute, University Health Network) single-blinded randomized controlled trial will be conducted whereby participants are randomized to either 12 weeks of at-home computerized executive function training or a wait-list control. Participants will consist of normal-hearing middle-aged adults (45-60 years old) and older adults (65-80 years old), as well as older hearing aid users (65-80 years old, ≥ 6 months hearing aid experience). Separate samples will undergo the same training protocol and the same pre- and post-evaluations of cognition, hearing, and mobility across sites. The primary dual-task outcome measures will involve either static balance (KITE site) or treadmill walking (Concordia site) with a secondary auditory-cognitive task. Dual-task performance will be assessed in an immersive virtual reality environment in KITE's StreetLab and brain activity will be measured using functional near infrared spectroscopy at Concordia's PERFORM Centre. DISCUSSION This research will establish the efficacy of an at-home cognitive training program on complex auditory and motor functioning under laboratory and simulated real-world conditions. This will contribute to rehabilitation strategies in order to mitigate or prevent physical and cognitive decline in older adults with hearing loss.

Abstract
Introduction This study aimed to investigate the daily sound exposure of hearing aid (HA) users during the COVID-19 pandemic, with a specific focus on the impact of different governance intervention levels. Methods Modern HA technology was employed to measure and compare the sound exposure of HA users in three distinct periods: pre-pandemic, and two 14-day periods during the pandemic, corresponding to varying levels of governance interventions. The study sample comprised a total of 386 HA users in Europe during the pandemic, with daily sound exposure data collected as part of the main dataset. Results The results revealed that, during the pandemic, the equivalent continuous sound pressure level (SPL) experienced by HA users decreased, while the signal-to-noise ratio (SNR) increased compared to the pre-pandemic period. Notably, this impact was found to be more pronounced (p < 0.05) when individuals were subjected to stronger governance intervention levels, characterized by lower SPL and higher SNR. Discussion This study highlights the changes in daily sound exposure experienced by HA users during the COVID-19 pandemic, particularly influenced by the extent of governance interventions that restricted social activities. These findings emphasize the importance of considering the effects of pandemic-related governance measures on the sound environments of HA users and have implications for audiological interventions and support strategies during similar crises.

Abstract
Objective: To explore the safety and reliability of retrosigmoid approach BONEBRIDGE implantation in patients with auricle reconstruction using skin expansion flap. Methods: A retrospective analysis was conducted on 43 congenital aural atresia cases (43 ears) who underwent BONEBRIDGE implantation from September 2019 to January 2023 in Beijing Tongren Hospital. 30 males and 13 females were included in this work. The implantation age was 9-36 years old (median age=10 y/o). All cases underwent auricle reconstruction surgery using the posterior ear flap expansion method, with 36 cases using the single expanded postauricular flap method and 7 cases using two-flap method. BONEBRIDGE implant surgery was performed during the third stage of auricle reconstruction or after all stages. The hearing improvements were evaluated by comparing the changes in pure tone hearing threshold and speech recognition rate of patients before and after BONEBRIDGE implantation. Routine follow-up was conducted to observe the hearing results and complications. SPSS 14.0 software was applied for data statistical analysis. Results: All 43 patients healed well and had no surgical complications when discharge. The average bone conduction hearing threshold after surgery was (8.2±6.6) dBHL, and there was no statistically significant difference compared to the preoperative [(8.1±5.7) dBHL] (P=0.95). After surgery, the threshold of hearing assistance with power on was significantly lower than that without hearing assistance [(32.8±4.6) dBHL vs (60.5±5.5) dBHL], and the difference was statistically significant (P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased to 72%, 84%, and 98% respectively. The differences were statistically significant (P<0.001). The speech recognition rate of monosyllabic words, disyllabic words, and short sentences in noise environment was significantly increased by 70%, 80%, and 92% respectively (P<0.001). After a follow-up of 4 to 47 months (median=24 months), the hearing results were stable and the aesthetic outcomes were satisfying. One patient had delayed hematoma around coil of the implant. After aspiration and compressed dressing for one week, hematoma was not recurrent. Conclusion: For patients after auricle reconstruction using expanded postauricular flap, the preference of retrosigmoid approach is a good choice in terms of safety and reliability of operation, as well as aesthetic appearance.

Feasibility of a Smartphone-Based Hearing Aid App for Mild-to-Moderate Hearing Loss: Prospective Multicenter Randomized Controlled Trial. JMIR Mhealth Uhealth 2023; 11:e46911. [PMID: 37800887 PMCID: PMC10578122 DOI: 10.2196/46911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 07/02/2023] [Accepted: 08/10/2023] [Indexed: 10/07/2023] Open
Abstract
Background Hearing loss is a growing health concern worldwide. Hearing aids (HAs) are the treatment of choice for hearing rehabilitation in most cases of mild-to-moderate hearing loss. However, many patients with hearing loss do not use HAs due to their high cost, stigma, and inaccessibility. Since smartphones are widely used, many apps that mimic the amplification function of HAs have been introduced. Smartphone-based HA apps (SHAAs) are affordable and easy to access. However, the audiological benefit of SHAAs has not been determined. Objective We compared the audiological performance between an SHAA and a conventional HA in a prospective, multicenter randomized controlled trial. Methods Patients with mild-to-moderate hearing loss were prospectively enrolled from 2 tertiary hospitals and randomly assigned to either an SHAA (Petralex; IT4YOU Corp LLC) or a conventional HA (Siya 1 miniRITE; Oticon A/S). For the cross-over study design, participants used the alternate device and repeated the same 2-month trial. Audiological measurements were obtained using hearing tests, real-ear measurements, and the hearing-in-noise test (HINT). Subjective satisfaction was evaluated using the Abbreviated Profile of Hearing Aid Benefit (APHAB) and International Outcome Inventory for Hearing Aids (IOI-HA). Results Overall, 63 participants were screened and 38 completed the study. In sound-field audiometry testing, the SHAA showed a 20- to 60-dB gain in the low-to-high frequencies of the hearing threshold level. The HA provided adequate gain in the middle-to-high frequencies (55, 65, and 75 dB in real-ear measurements), which is the sound level for most speaking volumes. However, the SHAA could not improve word recognition at 50 dB. The HA showed better audiological performance than the SHAA in both quiet and noisy conditions in the HINT. The IOI-HA scores were significantly improved by both the HA and SHAA versus unaided conditions. Among the SHAA users, 37% (14/38), 42% (16/38), 24% (9/38), and 32% (12/38) showed improvement in APHAB scores for ease of communication, reverberation, background noise, and aversiveness of sounds, respectively. There were no differences in adverse events between the 2 study groups. Conclusions The HA showed better performance than the SHAA in word recognition and the HINT. However, the SHAA was significantly better than unaided hearing in terms of amplification. The SHAA may be a useful hearing assistance device for patients with mild-to-moderate hearing loss when listening to soft sounds in quiet conditions. The SHAA demonstrated poorer performance than the HA in the mid- to high-frequency sounds that are important for word recognition, sound quality, and hearing in noisy conditions. Further development of the signal technology of SHAAs is needed to improve the sound quality of mid- to high-frequency sounds and overcome noisy environments.

Effect of Computerized Training Programs for Attention and Perception for Patients with Hearing Aids. Dement Geriatr Cogn Disord 2023; 52:304-308. [PMID: 37793349 DOI: 10.1159/000534156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Accepted: 09/13/2023] [Indexed: 10/06/2023] Open
Abstract
INTRODUCTION Sensorineural hearing loss is a common problem, especially among geriatric patients, and it requires hearing aids. Unfortunately, most geriatric patients are hesitant to use hearing aids. The purpose of this study was to investigate whether computerized training therapies increase the attention and perception of patients who have been given hearing aids using psychophysiological tests and wave P300 records. METHODS One hundred patients (40 women and 60 men) who used hearing aids were included in our study. Sixty patients (30 women and 30 men) received computerized training therapies with hearing aids. After the psychophysiological tests, the study group was divided into three groups according to the role given to patients. Passive training was given in group 1; interactive training was given in group 2; and group 3 was active, questioning training. Measurements of P300 wave latencies, stimuli-P300 peak, and baseline-P300 peak were performed before and after training. The control group consisted of 40 patients who did not receive training and were treated with hearing aids only. RESULTS We found a significant difference between the pre- and post-training measures of the P300 wave (p < 0.001). Pre-training measurements of P300 waves were recorded for 12% in group 1 and 9.1% in groups 2 and 3 (p = 0.24). Post-training measurements of the P300 wave records were 80% in group 1 and 72.7% in groups 2 and 3 (p = 0.22). CONCLUSION Attention and perception can be measured with the P300 wave. All computer-supported training programs showed an increase of the P300 wave, suggesting that attention and perception of patients with hearing loss can be increased with computer-supported training programs provided with hearing aids.

An Analysis of Mental State Verb and Complex Syntax Use in Children Who Are Deaf and Hard of Hearing. Lang Speech Hear Serv Sch 2023; 54:1282-1294. [PMID: 37696045 PMCID: PMC10721245 DOI: 10.1044/2023_lshss-23-00001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Revised: 05/15/2023] [Accepted: 07/10/2023] [Indexed: 09/13/2023] Open
Abstract
PURPOSE Children who are deaf and hard of hearing (DHH) have documented deficits with complex syntax and vocabulary knowledge. Mental state verbs (MSVs) are necessary for some kinds of complex syntax use and communicate abstract concepts needed for academic language. The purpose of this study was to examine the frequency, diversity, and syntactic context of MSV use in children who are DHH compared to children with typical hearing (CTH). METHOD Seventy-three preschool children (23 with cochlear implants, 22 with hearing aids, and 28 with typical hearing) completed a structured language sample as part of a larger assessment battery. Samples were analyzed and compared across groups for use of MSVs, diversity in MSV use, and syntactical context for MSVs. RESULTS Children who are DHH used significantly fewer MSV in complex syntax, a smaller diversity of MSV, and significantly fewer MSV in obligatory contexts compared to CTH. Results for the cochlear implants and hearing aid groups were not significantly different from one another despite differing levels of hearing loss. CONCLUSION Children who are DHH demonstrate significant differences in the rate, diversity, and complexity of MSV use compared to peers with typical hearing.

Consistent hearing aid use is associated with lower fall prevalence and risk in older adults with hearing loss. J Am Geriatr Soc 2023; 71:3163-3171. [PMID: 37314100 PMCID: PMC10592632 DOI: 10.1111/jgs.18461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 04/21/2023] [Accepted: 05/16/2023] [Indexed: 06/15/2023]
Abstract
BACKGROUND Falls and their sequelae cost more than $50 billion every year. Older adults with hearing loss are at 2.4 times greater risk of falls than their normal hearing peers. Current research is inconclusive about whether hearing aids can offset this increased fall risk, and no previous studies considered if outcomes differed based on the consistency of hearing aid use. METHODS Individuals 60 years and older with bilateral hearing loss completed a survey consisting of the Fall Risk Questionnaire (FRQ) and questions about hearing loss history, hearing aid use, and other common fall risk factors. In this cross-sectional study, fall prevalence, as well as fall risk (based on FRQ score), was compared between hearing aid users and non-users. A separate group of consistent hearing-aid users (at least 4 h daily use for more than 1 year) was also compared with inconsistent/non-users. RESULTS Responses from 299 surveys were analyzed. Bivariate analysis found 50% reduced odds of experiencing a fall for hearing aid users compared with non-users (OR = 0.50 [95% CI: 0.29-0.85], p = 0.01). After adjusting for age, sex, hearing loss severity, and medication usage, those who reported any hearing aid use still had lower odds of falls (OR = 0.48 [95% CI: 0.26-0.90], p = 0.02) and lower odds of being at risk for falls (OR = 0.36 [95% CI: 0.19-0.66] p < 0.001) than non-users. Results for consistent hearing aid users demonstrate an even stronger association of lowered odds of falling (OR = 0.35 [95% CI: 0.19-0.67], p < 0.001) and lower odds of being at risk for falls (OR = 0.32 [95% CI: 0.12-0.59], p < 0.001), suggesting a potential dose-response relationship. CONCLUSIONS These findings suggest that use of hearing aids-especially consistent hearing aid use-is associated with lower odds of experiencing a fall or being classified as at risk for falls in older individuals with hearing loss.

Surgical and audiological outcomes with a new transcutaneous bone conduction device with reduced transducer thickness in children. Eur Arch Otorhinolaryngol 2023; 280:4381-4389. [PMID: 37000276 PMCID: PMC10477095 DOI: 10.1007/s00405-023-07927-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Accepted: 03/13/2023] [Indexed: 04/01/2023]
Abstract
PURPOSE Due to smaller bone thickness, young children with conductive or mixed hearing loss or single-sided deafness were previously most commonly treated with a percutaneous osseointegrated bone-anchored hearing aid (BAHA) or an active middle-ear implant. While the BAHA increases the risk of implant infections, skin infection, overgrowth of the screw or involvement of the implant in head trauma, middle-ear implant surgery involves manipulation of the ossicles with possible risk of surgical trauma. These complications can be omitted with transcutaneous bone conduction implant systems like the MED-EL Bonebridge system. The purpose of this study was to analyze whether the second generation of the Bonebridge (BCI 602) that features a decreased implant thickness with a reduced surgical drilling depth can be implanted safely in young children with good postoperative hearing performance. METHODS In this study, 14 patients under 12 years were implanted with the second generation of the Bonebridge. Preoperative workup comprised a CT scan, an MRI scan, pure tone audiometry, or alternatively a BERA (bone conduction, air conduction). Since children under 12 years often have a lower bone thickness, the CT was performed to determine the suitability of the temporal bone for optimal implant placement using the Otoplan software. RESULTS All patients (including three under the age of five) were successfully implanted and showed a good postoperative hearing performance. CONCLUSION With adequate preoperative workup, this device can be safely implanted in children and even children under 5 years of age and allows for an extension of indication criteria toward younger children.

Abstract
OBJECTIVE This study aimed to analyse outcomes with hearing aid (HA) use and to determine whether common audiological tests, including pure-tone audiometry or word recognition test, correlate with HA wearers' subjective benefit. DESIGN A retrospective chart review. STUDY SAMPLE A total of 129 patients who adopted new HAs between January 2011 and December 2018 were enrolled. Outcome measures including pure tone thresholds, word recognition score (WRS), and self-reported questionnaires were obtained 1, 4, and 12 months post fit. RESULTS The mean aided threshold and WRS at each post-fit visit significantly improved from the unaided condition. Self-reported outcomes confirmed by the Hearing Handicap Inventory for the Elderly (HHIE) scores significantly improved compared to the unaided condition at 1- and 4-month follow-up. Results of the regression analysis indicated that the aided WRS score is a significant factor at all post-fit visits that explains less than 10% of the variance in HHIE scores. CONCLUSIONS Aided WRS is the factor most associated with subjectively reported HA outcomes, both in the short- and long term. Therefore, aided WRS should be considered as a useful tool for evaluating HA benefits, even after the prolonged use of HAs.

Abstract
OBJECTIVE To determine and compare the benefits a novel adhesive bone-conduction system and a conventional bone-conduction hearing aid (BCHA) on a softband for children with conductive hearing loss. STUDY DESIGN Prospective, single-subject randomized, crossover trial. SETTING Tertiary referral center in Australia. PARTICIPANTS Eight children aged from 4 to 17 years with conductive hearing loss. INTERVENTION Rehabilitative with participants using the novel adhesive bone-conduction aid and a BCHA. MAIN OUTCOME MEASURES Aided thresholds, as well as speech perception in quiet, unaided and aided with the novel adhesive bone-conduction aid and BCHA on a softband. For the six older children, speech in noise testing was also conducted. RESULTS The mean unaided four frequency average hearing levels was 48 dB HL for air conduction, 10.5 dB HL for bone conduction, with a mean air-bone gap in the aided ear of 37.5 dB HL.Four-frequency average hearing level aided thresholds were 20.2 dB for the novel device and 19.8 dB for the BCHA, with no significant difference between the devices. Aided monosyllabic word scores improved from an average of 45% in the unaided condition to 81.6 and 85% for the novel adhesive and BCHA devices, respectively. Aided speech in noise performance improved, on average, by 1.6 dB SNR when wearing the BCHA and the novel adhesive device, with no significant difference in performance between the two devices. CONCLUSIONS The novel device provided equivalent performance to the BCHA on all measures and can be considered as an alternative device for pediatric patients with conductive hearing loss.

Abstract
OBJECTIVE To explore the rate and effect factors of hearing aids utilization in Chinese community elderly people, as well as the benefit role of hearing aids in the association of hearing loss and cognition decline. METHODS This study was designed based on a longitudinal 7-years follow-up conducted in Shanghai (China). Demographic characteristics, hearing level, hearing aids utilization and Activities of Daily Living (ADL) of participants were collected by Unified Needs Assessment Form for Elderly Care Questionnaire. Cognition function was assessed by Mini-mental State Examination (MMSE) scale. Multivariate logistic regression and linear regression were used for statistical analysis. RESULTS Hearing aids utilization rate in Chinese community elderly people is below 10 %. Participants with older age (≥80 years old), higher education (7-12 years and >12 years), who can manage money more independently were more likely to use hearing aids (P < 0.05). Whether hearing aids are used or not, hearing level is significantly associated with cognition in elderly people, but participants with hearing aids showed a slower cognitive decline speed. CONCLUSION Hearing aids utilization may slow down the cognition descent via assisting hearing in daily life, so strategies need to be concerned in order to protect hearing function in all elderly and improve the use of hearing aids in HL elderly.

Abstract
OBJECTIVE This study aimed to evaluate the association between certain social determinants of health (i.e. educational level, income, and social support) and attitudes towards hearing loss and hearing aids among older adults with hearing loss fitted in a Latin American country. DESIGN Older adults were asked about their attitudes towards hearing loss and hearing aids, years of formal education, income, social support, perception of having a hearing disability, and social pressure when using the hearing aid. To do so, we adapted the Attitudes towards Loss of Hearing Questionnaire (S-ALHQ) into Spanish. All the questionnaires were conducted as structured interview. STUDY SAMPLE Two hundred fifty-two older hearing aids users were recruited from a public hospital in Chile. RESULTS The S-ALHQ showed adequate validity, along with good reliability. The multivariate models showed that educational level and social support were the social determinants of health negatively associated with the attitudes. Aided hearing disability and social pressure to use hearing aids were the co-variables associated with S-ALHQ scores. CONCLUSIONS The study showed a significant relationship between specific social determinants of health and attitudes towards hearing loss and hearing aids. These attitudes should be considered when implementing rehabilitation programs for older adults with hearing loss.

Abstract
PURPOSE Hearing rehabilitation through middle ear surgery can be challenging, particularly for patients with chronic otitis media, but new hearing devices offer opportunity to reach this goal. The aim was to compare hearing outcomes and quality of life in patients who were converted from a Baha Attract system to the Osia system. METHODS Prospective observational study, in which each subject acted as their own control. Six patients who were converted from a Baha Attract to an Osia system performed audiometric and quality of life assessments with different sound processor at fitting, 3, 6 and 12 months. The speech performance in noise with the Osia system at 12 months, expressed as dB SNR, was compared to the baseline condition (Baha 5). RESULTS The PTA4 hearing thresholds improved from 42.6 ± 11 with Baha 5 Power to 34.8 ± 13.3 with Baha 5 SuperPower and to 25.4 ± 3.5 with the Osia at 12 months, leading to a significant functional gain of 17.2 ± 10.9 dB vs Baha 5 (p < 0.02). Speech understanding in both quiet and noise was clinically improved reaching a mean SNR of less than 1 dB at 12 months with the Osia system. Quality of life outcomes improved by more than 20% at 12-month follow-up. CONCLUSION Aided hearing thresholds and speech understanding in noise improved when patients were converted from the Baha Attract system to the Osia system. The aided hearing threshold was maintained up to 8 kHz (26 dB) with the Osia system.

Objective discrimination of bimodal speech using frequency following responses. Hear Res 2023; 437:108853. [PMID: 37441879 DOI: 10.1016/j.heares.2023.108853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 07/03/2023] [Accepted: 07/08/2023] [Indexed: 07/15/2023]
Abstract
Bimodal hearing, in which a contralateral hearing aid is combined with a cochlear implant (CI), provides greater speech recognition benefits than using a CI alone. Factors predicting individual bimodal patient success are not fully understood. Previous studies have shown that bimodal benefits may be driven by a patient's ability to extract fundamental frequency (f0) and/or temporal fine structure cues (e.g., F1). Both of these features may be represented in frequency following responses (FFR) to bimodal speech. Thus, the goals of this study were to: 1) parametrically examine neural encoding of f0 and F1 in simulated bimodal speech conditions; 2) examine objective discrimination of FFRs to bimodal speech conditions using machine learning; 3) explore whether FFRs are predictive of perceptual bimodal benefit. Three vowels (/ε/, /i/, and /ʊ/) with identical f0 were manipulated by a vocoder (right ear) and low-pass filters (left ear) to create five bimodal simulations for evoking FFRs: Vocoder-only, Vocoder +125 Hz, Vocoder +250 Hz, Vocoder +500 Hz, and Vocoder +750 Hz. Perceptual performance on the BKB-SIN test was also measured using the same five configurations. Results suggested that neural representation of f0 and F1 FFR components were enhanced with increasing acoustic bandwidth in the simulated "non-implanted" ear. As spectral differences between vowels emerged in the FFRs with increased acoustic bandwidth, FFRs were more accurately classified and discriminated using a machine learning algorithm. Enhancement of f0 and F1 neural encoding with increasing bandwidth were collectively predictive of perceptual bimodal benefit on a speech-in-noise task. Given these results, FFR may be a useful tool to objectively assess individual variability in bimodal hearing.

Abstract
PURPOSE The purpose of the study was to obtain, analyze, and compare subjective sound quality data for the same test stimuli using modified multistimulus MUSHRA (Multiple Stimulus with Hidden Reference and Anchors) based procedures (viz., MUSHRA with custom anchors and MUSHRA without anchor) and the single-stimulus Gabrielsson's total impression rating procedure. METHOD Twenty normally hearing young adults were recruited in this study. Participants completed sound quality ratings on two different hearing aid recording data sets-Data Set A contained speech recordings from four different hearing aids under a variety of noisy and processing conditions, and Data Set B contained speech recordings from a single hearing aid under a combination of different noisy, reverberant, and signal processing conditions. Recordings in both data sets were rated for their quality using the total impression rating procedure. In addition, quality ratings of Data Set A recordings were obtained using a MUSHRA with custom anchors, while the ratings of Data Set B recordings were collected using a MUSHRA without anchor. RESULTS Statistical analyses revealed a high test-retest reliability of quality ratings for the same stimuli that were rated multiple times. In addition, high-interrater reliability was observed with all three rating procedures. Further analyses indicated (a) a high correlation between the total impression rating and the two modified MUSHRA ratings and (b) a similar relationship between the average and standard deviation of the subjective rating data obtained by the total impression rating and MUSHRA with custom anchors on Data Set A, and the total impression rating and the MUSHRA without anchor on Data Set B. CONCLUSION Both sound quality procedures, namely, the MUSHRA-based procedures and the total impression rating scale, obtained similar quality ratings of varied hearing aid speech recordings with high reliability.

Abstract
PURPOSE The purpose of this study was to evaluate how the EasyGain settings on a wireless receiver used with a remote microphone (RM) affected output as a function of hearing loss and receiver type. METHOD To assess the effects of the EasyGain setting on a Roger receiver, a Phonak Naida V90 superpower hearing aid (HA), two universal Roger X (02) receivers, two Roger 18 integrated receivers, and a Roger Inspiro transmitter were used. An electroacoustic evaluation was performed for five degrees of hearing loss ranging from a flat 40 to 80 dB HL, and for nine EasyGain settings from +8 to -8 dB with each Roger receiver. RESULTS A three-way analysis of variance indicated significant main effects of hearing loss, receiver type and EasyGain settings, as well as their two-way interactions (p < .05). Overall, the output of the integrated receiver was 2.77 dB higher than that of the universal receiver. The change in output with 2-dB changes in EasyGain setting varied with the degree of hearing loss. For mild hearing loss (40 and 50 dB), every 2-dB change in EasyGain produced an average of 1.93 dB (SD = 0.17) change in the root-mean-square (RMS) output. For the higher degrees of hearing loss (60, 70, and 80 dB HL), the change in RMS varied depending on the range of EasyGain setting as follows: when EasyGain was > 0 dB, every 2-dB change in EasyGain setting produced an average change in RMS output of 1.32 dB (SD = 0.41); however, when EasyGain was ≤ 0 dB, every 2-dB change resulted in a mean 1.95 dB (SD = 0.16) change. CONCLUSIONS The benefits of EasyGain technology on the RMS output are dependent on the interaction of the receiver type, degree of hearing loss, and EasyGain settings. The results highlight the importance of electroacoustic verification to determine appropriate settings for optimal audibility when using an RM system.

In-situ hearing threshold estimation using Gaussian process classification. Sci Rep 2023; 13:14667. [PMID: 37673944 PMCID: PMC10482858 DOI: 10.1038/s41598-023-40495-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Accepted: 08/11/2023] [Indexed: 09/08/2023] Open
Abstract
One in six Americans suffers from hearing loss. While treatment with amplification is possible for many, the acceptance rate of hearing aids is low. Poor device fitting is one of the reasons. The hearing aid fitting starts with a detailed hearing assessment by a trained audiologist in a sound-controlled environment, using standard equipment. The hearing aid is adjusted step-by-step, following well-described procedures based on the audiogram. However, for many patients in rural settings, considerable travel time to a hearing center discourages them from receiving a hearing test and treatment. We hypothesize that hearing assessment with the patient's hearing aid can reliably substitute the hearing test in the clinic. Over-the-counter hearing aids could be programmed from a distance and fine-tuned by the hearing aid wearer. This study shows that a patient-controlled hearing assessment via a hearing aid in a non-clinical setting is not statistically different from an audiologist-controlled hearing assessment in a clinical setting. The differences in hearing obtained with our device and the Gaussian Process are within 3 dB of the standard audiogram. At 250 Hz, the sound delivery with the hearing aid used in this study added an additional reduction of sound level, which was not compensated.

Abstract
PURPOSE This study was aimed at understanding the effect of time taken to adapt to the new hearing aids (HAs) and the timeline of HA adjustments performed over more than a year of rehabilitation on self-reported HA outcomes. METHOD A self-report of the time it took to get accustomed to the new HAs and adjustment of the HAs during a year of rehabilitation collected from 690 HA users using a nonstandardized questionnaire were analyzed. The abbreviated version of the Speech, Spatial, and Quality of Hearing questionnaire and the International Outcome Inventory for Hearing Aids were used as the self-reported HA outcome. RESULT Out of 690 participants, 442 (64%) got accustomed to HAs within 2 months. Ninety-one participants (13%) did not get accustomed to the HAs at all, out of which 74 (81%) were first-time HA users. Eighty-four participants (12%) did not receive any HA adjustments after their initial fitting, and 49 (7%) had their HAs adjusted four or more times during the 1 year of rehabilitation. Three hundred ninety (57%) participants got their HA adjusted only at the 2-month follow-up visit, showing the intent to adjust given an opportunity. The stepwise multiple linear regression results showed the significant impact of getting accustomed to the HA and having HA adjusted at multiple instances on the self-reported HA outcomes. CONCLUSION This study showed the importance of getting accustomed to the HA and having a minimal number of adjustments to have a better long-term self-reported HA outcome.

Abstract
PURPOSE Hearing loss is most prevalent among older adults, yet underestimated by patients, clinicians, and research communities. This study aimed to assess the accuracy of self-reported hearing difficulties among a group of adults aged 61-63 years, against audiometric measures. METHOD The analysis used a sample (N = 346) of the Newcastle Thousand Families Study birth cohort. Data from audiological examinations and self-reported hearing difficulties were used to compare subjective and objective hearing. Hearing aid use was also assessed. RESULTS Over 40% of the participants had some level of hearing loss (n = 155, 44.8%), and 31% (n = 133) of these reported having hearing problems during subjective assessment. Only 18 (10%) of those with objectively measured hearing loss reported using hearing aids. CONCLUSIONS There was an inconsistency between measured and self-perceived hearing loss among adults aged 61-63 years in this cohort. The small number of hearing aid users in the cohort is a concern, in that people in this age group appear not to be getting the help they need. The data also add to the research evidence that people at this age underestimate their hearing loss.

Parental insights on Hearing Aid Usage in the ear Contralateral to unilateral Cochlear Implant among Children. Int J Pediatr Otorhinolaryngol 2023; 172:111656. [PMID: 37494774 DOI: 10.1016/j.ijporl.2023.111656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 06/21/2023] [Accepted: 07/09/2023] [Indexed: 07/28/2023]
Abstract
AIM & OBJECTIVES The aim of the present study was in three-fold: (a) to analyze the factors that affect the hearing aid (HA) continuation/discontinuation in children with unilateral cochlear implant (CI); (b) to understand the parent's knowledge on binaural benefit; and (c) to find out any association between the hearing aid continuation/discontinuation with implant age and/or with duration of hearing aid use prior to surgery. METHOD The study involved 97 participants who were parents of children with unilateral cochlear implants. A questionnaire with 30 questions was used to explore HA use and certain related perceptions, and a Likert scale was used for ranking responses. RESULTS & Discussion: Only 31.9% children were using HA consistently, post CI activation The principal factor for discontinuation of HA was its helpfulness prior CI whereas children wore HA only because they were instructed during counseling. Participants did not perceive functional benefit bimodal fitting due to superiority of CI performance and poor residual hearing. Also, it was found that there is no association between neither the implant age nor duration of HA use before CI with the HA continuation/discontinuation on Chi-square test. CONCLUSIONS The results suggest a need for structured comprehensive counseling and demonstration sessions to educate parents on binaural hearing to gain maximum benefits from non-invasive bimodal fitting.
