The error patterns of phonemes in children with prelingual hearing loss: A comparison between hearing aid and cochlear implant users. Auris Nasus Larynx 2024; 51:537-541. [PMID: 38537556 DOI: 10.1016/j.anl.2024.01.001] [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: 07/08/2023] [Revised: 11/19/2023] [Accepted: 01/12/2024] [Indexed: 05/12/2024]
Abstract
OBJECTIVE To reveal differences in error pattern of phonemes and articulation between children using cochlear implants (CIs) and those using hearing aids (HAs) due to prelingual hearing disorder and help the education of children with prelingual hearing loss. METHOD Children with prelingual hearing loss who were receiving auditory-verbal preschool education at an auditory center for hearing-impaired children (Fujimidai Auditory Center, Tokyo, Japan) from 2010 to 2020 were analyzed retrospectively. All participants underwent pure tone audiometry and monosyllabic intelligibility tests. The error answers were categorized into five patterns which was characterized by the substitution, addition, omission, failure, and no response according to consonant errors. In addition, the consonant errors classified into the manner of articulation and the differences of error patterns were analyzed between the HA and the CI group descriptively. RESULTS A total of 43 children with bilateral HAs and 46 children with bimodal CIs or bilateral CIs were enrolled. No significant between-group differences in median phoneme intelligibility were found. The most common error pattern was substitution in both HA and CI groups. The error number of addition pattern in the HA group was smaller than in the CI group. In both groups, the most common errors of articulation were flap errors, and the most common error patterns were flaps to nasals, nasals to nasals, plosives to plosives. In the HA group, plosives and nasals tended not to be recognized and in the CI group plosives were prone to be added to vowels. CONCLUSIONS There were some different error patterns of articulation and consonant substitution between groups. Clarifying differences of phoneme that are difficult to hear and tend to be misheard would help for creating an effective approach to auditory training for children with hearing loss.

Abstract
OBJECTIVE Severely asymmetrical hearing loss (SAHL) is characterized by a moderately severe or severe hearing loss in one side and normal or mildly impaired controlateral hearing in the other. The Active tri-CROS combines the Contralateral Routing-of-Signal System (CROS, or BiCROS if the best ear is stimulated) and the stimulation of the worst ear by an in-the-canal hearing aid. This study aims to evaluate the benefit of the Active tri-CROS for SAHL patients. STUDY DESIGN This retrospective study was conducted from September 2019 to December 2020. SETTING Ambulatory, tertiary care. PATIENTS Patients were retrospectively included if they had received the Active tri-CROS system after having used a CROS or BiCROS system for SAHL for at least 3 years. MAIN OUTCOME MEASURES Audiometric gain, signal-to-noise ratio, spatial localization, and the Abbreviated Profile of Hearing Aid Benefit and Tinnitus Handicap Inventory questionnaires were performed before equipment and after a month with the system. RESULTS Twenty patients (mean, 62 yr old) with a mean of 74.3 ± 8.7 dB HL on the worst ear were included. The mean tonal hearing gain on the worst ear was 20 ± 6 dB. Signal-to-noise ratio significantly rose from 1.43 ± 3.9 to 0.16 ± 3.4 dB ( p = 0.0001). Spatial localization was not significantly improved. The mean Tinnitus Handicap Inventory test score of the eight patients suffering from tinnitus rose from 45.5 ± 18.5 to 31 ± 25.2 ( p = 0.016). CONCLUSIONS The Active tri-CROS system is a promising new therapeutically solution for SAHL.

Abstract
OBJECTIVE To investigate the feasibility of early sound processor loading with two separate bone-anchored hearing aid implants 1 to 2 weeks after implantation. Secondary endpoints included registration of any postoperative complications, skin reactions, and any adverse events. STUDY DESIGN Prospective, nonrandomized, noncontrolled, multicenter clinical trial. SETTING Tertiary referral center. PATIENTS Sixty adult patients, eligible for bone-anchored hearing aid surgery, were enrolled. INTERVENTION Implantation of the bone-anchored hearing aid implants were done using minimally invasive surgery with tissue preservation. MAIN OUTCOME MEASURE Implant stability quotient (ISQ) values were recorded using resonance frequency analysis. Follow-ups were scheduled 5 to 12 days, 4 to 8 weeks, 6 months, and 12 months postoperatively. Differences between the lowest ISQ values (ISQ low) over time were analyzed by paired-samples t test with a significance level of 0.05. Skin and soft tissue reactions were assessed according to Holger's classification. RESULTS Loading time of the Ponto Wide implant was 11.6 ± 1.4 days (SD) in average (median, 12 d; range, 7-19 d). Loading of the Ponto BHX implant was done 9.7 ± 3.5 days (SD) postoperatively (median, 9 d; range, 5-19 d). The implant stability increased significantly during the 12-month study period with both implants. One Ponto BHX implant was lost. Skin and soft tissue reactions were few in both groups. Across all planned follow-up visits, no skin and soft tissue reactions were observed in 86% (Ponto BHX implant) and 85% (Ponto Wide implant). CONCLUSION Very early loading of sound processors after percutaneous bone-anchored hearing system surgery is safe already 1 to 2 weeks postoperatively.

Abstract
OBJECTIVE This study evaluates the clinical outcomes of 807 percutaneous wide-diameter bone-anchored hearing implants (BAHIs) in 701 patients. In addition, it compares patient groups and examines bone conduction device (BCD) usage. STUDY DESIGN Retrospective cohort study. Mean follow-up period of 3.8 years. SETTING Tertiary referral center. PATIENTS All patients implanted with a percutaneous wide-diameter BAHI until December 2020 were included. Patients were divided into age groups, "loading-time" groups, and, if applicable, specific subgroups thought to be at risk for complications postsurgery, e.g., intellectual disability and comorbidities. MAIN OUTCOME MEASURES Soft tissue reaction, implant survival, revision surgery, and BCD usage. RESULTS In 9.1% of the 5,188 observations of 807 implants, an adverse soft tissue reaction was reported according to the Holgers' scale. Significantly more (adverse) soft tissue reactions were observed in children and intellectually disabled (ID) patients (p < 0.05). Comorbidity subgroups showed no significant differences in soft tissue reactions. Implant loss percentage, including explantations, was 6.2%. Implant survival was significantly worse in patients with ID (14.1%; p = 0.021). Pediatric age, early loading, or comorbidities did not significantly influence implant survival. At least 592 implants (73.4%) were used for bone conduction hearing, of which 65.4% were used daily. CONCLUSION Both children and ID patients are more prone to (adverse) soft tissue reactions, ID patients only have a higher risk of implant loss. The rate of implant loss in children seemed to be reduced compared to previous studies and thus more comparable to adults since using wide-diameter implants.

Functional outcomes for speech-in-noise intelligibility of NAL-NL2 and DSL v.5 prescriptive fitting rules in hearing aid users. Eur Arch Otorhinolaryngol 2024; 281:3227-3235. [PMID: 38546852 DOI: 10.1007/s00405-024-08587-z] [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: 12/13/2023] [Accepted: 02/27/2024] [Indexed: 05/03/2024]
Abstract
PURPOSE The primary aim of this research study is to assess whether differences exist in the application of the NAL-NL2 and DSL v.5 prescription formulas in terms of speech-in-noise intelligibility. METHODS Data from 43 patients, were retrospectively evaluated and analyzed. Inclusion criteria were patients with bilateral conductive, sensorineural, or mixed hearing loss, already using hearing aids for at least 1 year, and aged 18 years or older. Patients were categorized into two groups based on the prescriptive method employed by the hearing aid: NAL-NL2 or DSL v.5. Pure tone audiometry, speech audiometry, free field pure tone and speech audiometry with the hearing aid, and Matrix sentence test were performed. The Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire was used to assess the personal audiological benefit provided by the hearing aid. RESULTS No statistically significant differences were found comparing the free-field pure tone average (FF PTA) and the free-field Word Recognition Score (FF WRS). Comparing the Speech Reception Threshold (SRT) parameter of patients with NAL-NL2 vs DSL v.5, no statistically significant difference was found, thus highlighting a condition of comparability between the two prescription methods in terms of speech-in-noise intelligibility. Comparing the results of the APHAB questionnaire, no statistically significant differences were evident for all subscales and overall benefit. When conducting a comparison between male and female patients using the NAL-NL2 method, no differences were observed in SRT values, however, the APHAB questionnaire revealed a difference in the AV subscale score for the same subjects. CONCLUSION Our analysis revealed no statistically significant differences in speech-in-noise intelligibility, as measured by the SRT values from the Matrix Sentence Test, when comparing the two prescriptive methods. This compelling result reinforces the notion that, functionally, both methods are comparably effective in enhancing speech intelligibility in real-world, noisy environments. However, it is crucial to underscore that the absence of differences does not diminish the importance of considering individual patient needs and preferences in the selection of a prescriptive method.

Abstract
PURPOSE The indications of Vibrant Soundbridge (VSB) have been expanded to include patients with conductive and mixed hearing loss due to congenital aural atresia (CAA). However, the current evidence supporting the auditory outcomes of VSB is based mainly on case reports and retrospective chart reviews. Therefore, the present systematic review aims to summarize and critically appraise the current evidence regarding the safety and effectiveness of VSB in children and adult patients with CAA. METHODS A systematic literature search retrieved studies that evaluated the outcomes of unilateral or bilateral implantation of VSB in patients with CAA. The bibliographic search was conducted in PubMed, Scopus, EBSCO, and Cochrane Central Register of Controlled Trials (CENTRAL) databases from January 2000 to December 2022. RESULTS Twenty-seven studies were included in the present systematic review. Overall, the speech perception after VSB was good, with a mean word recognition score (WRS) score ranging from 60 to 96.7%. The mean postoperative speech recognition threshold (SRT) after implantation ranged from 20.8 to 50 dB. The effective gain was reported in 15 studies, ranging from 31.3 to 45.5 dB. In terms of user satisfaction with VSB, the included studies showed significant improvements in the patient-reported outcomes, such as the Speech Spatial and Qualities of Hearing scale and Glasgow Hearing Aid Benefit Profile. The VSB implantation was generally safe with low incidence of postoperative complications. CONCLUSION VSB provides significant benefits to individuals with hearing loss owing to CAA, with very good subjective outcomes and a low risk of complications.

Deep learning-based auditory attention decoding in listeners with hearing impairment . J Neural Eng 2024; 21:036022. [PMID: 38729132 DOI: 10.1088/1741-2552/ad49d7] [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: 06/02/2023] [Accepted: 05/10/2024] [Indexed: 05/12/2024]
Abstract
Objective.This study develops a deep learning (DL) method for fast auditory attention decoding (AAD) using electroencephalography (EEG) from listeners with hearing impairment (HI). It addresses three classification tasks: differentiating noise from speech-in-noise, classifying the direction of attended speech (left vs. right) and identifying the activation status of hearing aid noise reduction algorithms (OFF vs. ON). These tasks contribute to our understanding of how hearing technology influences auditory processing in the hearing-impaired population.Approach.Deep convolutional neural network (DCNN) models were designed for each task. Two training strategies were employed to clarify the impact of data splitting on AAD tasks: inter-trial, where the testing set used classification windows from trials that the training set had not seen, and intra-trial, where the testing set used unseen classification windows from trials where other segments were seen during training. The models were evaluated on EEG data from 31 participants with HI, listening to competing talkers amidst background noise.Main results.Using 1 s classification windows, DCNN models achieve accuracy (ACC) of 69.8%, 73.3% and 82.9% and area-under-curve (AUC) of 77.2%, 80.6% and 92.1% for the three tasks respectively on inter-trial strategy. In the intra-trial strategy, they achieved ACC of 87.9%, 80.1% and 97.5%, along with AUC of 94.6%, 89.1%, and 99.8%. Our DCNN models show good performance on short 1 s EEG samples, making them suitable for real-world applications. Conclusion: Our DCNN models successfully addressed three tasks with short 1 s EEG windows from participants with HI, showcasing their potential. While the inter-trial strategy demonstrated promise for assessing AAD, the intra-trial approach yielded inflated results, underscoring the important role of proper data splitting in EEG-based AAD tasks.Significance.Our findings showcase the promising potential of EEG-based tools for assessing auditory attention in clinical contexts and advancing hearing technology, while also promoting further exploration of alternative DL architectures and their potential constraints.

Abstract
OBJECTIVES In this study, we aimed to describe differences in diagnosis and both auditory and speech/language intervention utilization between children with permanent unilateral hearing loss as compared with bilateral hearing loss. DESIGN A retrospective cohort study was performed of children evaluated in a multidisciplinary hearing loss clinic at a tertiary care pediatric hospital. Children aged 0 to 18 years with either permanent unilateral or bilateral hearing loss were included. RESULTS One hundred fourteen children with unilateral hearing loss and 268 children with bilateral hearing loss were studied for a total of 382 children. There were no demographic differences between children with permanent unilateral versus bilateral hearing loss. Rates of newborn hearing screening and referred screening results were similar between those with unilateral and bilateral hearing loss. Despite similar rates of referred newborn hearing screening, those with bilateral hearing loss were diagnosed at a younger age (mean 3.6 years, SD 3.8 years) as compared with those with unilateral hearing loss (mean 5.0 years, SD 4.2 years). Children with unilateral hearing loss had similar severity of hearing loss in their poorer hearing ear as compared with children with bilateral hearing loss, yet they were significantly less likely to be fitted with hearing devices (53% versus 78%) or receive speech/language therapy (36% versus 54%) as compared with children with bilateral hearing loss. Multivariate analysis found that bilateral hearing loss and earlier age of hearing loss diagnosis were associated with hearing device use. CONCLUSIONS Early diagnosis and intervention for childhood hearing loss have a significant impact on a child's educational success and social relationships. However, little is known about differences in diagnosis and resource utilization between children with permanent unilateral hearing loss versus bilateral hearing loss. Children with unilateral hearing loss were diagnosed at a later age and were less likely to utilize hearing devices or speech/language therapy compared with those with bilateral hearing loss, despite having similar severity of hearing loss in the poorer hearing ear. There is a strong body of evidence that children with unilateral hearing loss have improved hearing outcomes with hearing devices, which suggests there is room for improvement in identifying unilateral hearing loss and providing adequate services to optimize educational success. However, speech therapy is generally implemented in response to language delays. Therefore, children with unilateral loss may have lower rates of language delays as compared with those with bilateral hearing loss, thereby explaining differences in speech therapy utilization.

Age standardization and time-of-day performance for the Oldenburg Sentence Test (OLSA): results from the population-based Gutenberg Health Study. Eur Arch Otorhinolaryngol 2024; 281:2341-2351. [PMID: 38110748 PMCID: PMC11023958 DOI: 10.1007/s00405-023-08358-2] [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: 09/08/2022] [Accepted: 11/15/2023] [Indexed: 12/20/2023]
Abstract
PURPOSE The Oldenburg Sentence Test (OLSA) is a German matrix test designed to determine speech recognition thresholds (SRT). It is widely used for hearing-aids and cochlear implant fitting, but an age-adjusted standard is still lacking. In addition, knowing that the ability to concentrate is an important factor in OLSA performance, we hypothesized that OLSA performance would depend on the time of day it was administered. The aim of this study was to propose an age standardization for the OLSA and to determine its diurnal performance. METHODS The Gutenberg Health Study is an ongoing population-based study and designed as a single-centre observational, prospective cohort study. Participants were interviewed about common otologic symptoms and tested with pure-tone audiometry and OLSA. Two groups-subjects with and without hearing loss-were established. The OLSA was performed in two runs. The SRT was evaluated for each participant. Results were characterized by age in 5-year cohorts, gender and speech recognition threshold (SRT). A time stamp with an hourly interval was also implemented. RESULTS The mean OLSA SRT was - 6.9 ± 1.0 dB (group 1 male) and - 7.1 ± 0.8 dB (group 1 female) showing an inverse relationship with age in the whole cohort, whereas a linear increase was observed in those without hearing loss. OLSA-SRT values increased more in males than in females with increasing age. No statistical significance was found for the diurnal performance. CONCLUSIONS A study with 2900 evaluable Oldenburg Sentence Tests is a novelty and representative for the population of Mainz and its surroundings. We postulate an age- and gender-standardized scale for the evaluation of the OLSA. In fact, with an intergroup standard deviation (of about 1.5 dB) compared to the age dependence of 0.7 dB/10 years, this age normalization should be considered as clinically relevant.

Abstract
OBJECTIVE Stress levels among caregivers of children with hearing loss could influence caregiver-child interactions and ultimately, children's developmental outcomes. Given the limited understanding of stress levels among caregivers of Australian children with hearing loss, the present study aimed to examine stress in caregivers of 5-year-old children with hearing loss wearing hearing aids or cochlear implants and to identify factors associated with greater stress levels. METHODS A total of 99 caregivers of 70 hearing aid users and 29 cochlear implant users participated in the study. Caregivers' stress was measured using the 68-item Pediatric Hearing Impairment Caregiver Experience (PHICE) questionnaire that examines caregivers' context-specific stress levels in relation to caring for a child with hearing loss. Factors contributing to stress were identified in relation to eight domains including communication, education, emotional well-being, equipment, financial, healthcare, social, and support. RESULTS Across domains, the three most common predictors of increased stress were the use of cochlear implants over hearing aids, use of sign and oral language (mixed) over oral language as the communication mode at home, and increased behavioural difficulties of the child. CONCLUSION Overall, reported stress levels among Australian caregivers were low. Identified factors influencing stress levels can inform service provision improvement.

Abstract
OBJECTIVE This study investigated the adjustment behaviour of hearing aid (HA) users participating in a semi-supervised self-adjustment fine-tuning procedure for HAs. The aim was to link behaviour with the reproducibility and duration of the adjustments. DESIGN Participants used a two-dimensional user interface to identify their HA gain preferences while listening to realistic sound scenes presented in a laboratory environment. The interface allowed participants to adjust amplitude (vertical axis) and spectral slope (horizontal axis) simultaneously. Participants were clustered according to their interaction with the user interface, and their search directions were analysed. STUDY SAMPLE Twenty older experienced HA users were invited to participate in this study. RESULTS We identified four different archetypes of adjustment behaviour (curious, cautious, semi-browsing, and full-on browsing) by analysing the trace points of all measurements for each participant. Furthermore, participants used predominantly horizontal or vertical paths when searching for their preference. Neither the archetype, nor the search directions, nor the participants' technology commitment was predictive of the reproducibility or the adjustment duration. CONCLUSIONS The findings suggest that enforcement of a specific adjustment behaviour or search direction is not necessary to obtain fast, reliable self-adjustments. Furthermore, no strict requirements with respect to technology commitment are necessary.

Abstract
OBJECTIVES The study aimed to develop and validate the Mandarin digit-in-noise (DIN) test using four digit (i.e., two-, three-, four-, and five-digit) sequences. Test-retest reliability and criterion validity were evaluated. How the number of digits affected the results was examined. The research might lead to more informed choice of DIN tests for populations with specific cognitive needs such as memory impairment. DESIGN The International Collegium of Rehabilitative Audiology guideline for developing the DIN was adapted to create test materials. The test-retest reliability and psychometric function of each digit sequence were determined among young normal-hearing adults. The criterion validity of each digit sequence was determined by comparing the measured performance of older adult hearing aid users with that obtained from two other well-established sentence-in-noise tests: the Mandarin hearing-in-noise test and the Mandarin Chinese matrix test. The relation between the speech reception thresholds (SRTs) of each digit sequence of the DIN test and working memory capacity measured using the digit span test and the reading span test were explored among older adult hearing aid users. Together, the study sample consisted of 54 young normal-hearing adults and 56 older adult hearing aid users. RESULTS The slopes associated with the two-, three-, four-, and five-digit DIN test were 16.58, 18.79, 20.42, and 21.09 %/dB, respectively, and the mean SRTs were -11.11, -10.99, -10.56, and -10.02 dB SNR, respectively. Test-retest SRTs did not differ by more than 0.74 dB across all digit sequences, suggesting good test-retest reliability. Spearman rank-order correlation coefficients between SRTs obtained using the DIN across the four digit (i.e., two-, three-, four-, and five-digit) sequences and the two sentence-in-noise tests were uniformly high ( rs = 0.9) across all participants, when data from all participants were considered. Results from the digit span test and reading span test correlated significantly with the results of the five-digit sequences ( rs = -0.37 and -0.42, respectively) but not with the results of the two-, three-, and four-digit sequences among older hearing aid users. CONCLUSIONS While the three-digit sequence was found to be appropriate for clinical use for assessment of auditory perception, the two-digit sequence could be used for hearing screening. The five-digit sequence could be difficult for older hearing aid users, and with its SRT related to working memory capacity, its use in the evaluation of speech perception should be investigated further. The Mandarin DIN test was found to be reliable, and the findings are in line with SRTs obtained using standardized sentence tests, suggesting good criterion validity.

Abstract
BACKGROUND There has been a significant increase in scientific investigations of the hearing-dementia association among the research on potentially modifiable risk factors for cognitive impairment. We tested two clinical questions. Analysis 1: does persistent hearing aid (HA) use decrease the decline in cognitive function caused by ageing? Analysis 2: does cognitive function at the time of HA fitting predict future persistent HA use? METHODS This case-control study performed at two referral centres reported data obtained over a 4.5-year period. We recruited a group of patients with cognitive decline, aged 65 or older with or without hearing loss. The intervention consisted of the use of HAs. The primary outcome measures were adherence to continuous HA use and cognitive function measured using the Japanese version of the Mini-Mental State Examination Test and the Reading Cognitive Test Kyoto. RESULTS Eighteen HA users and 18 controls were included in the first analysis. HA use was associated with a deceleration of cognitive decline 12 months later. In the second analysis, 11 participants with good adherence to HA use were compared with 12 participants who showed poor adherence to HA use. Among the variables employed in this study, cognitive function measured using the Reading Cognitive Test Kyoto was significantly lower in participants with poor adherence to HA. CONCLUSIONS HA use in cognitively impaired individuals with hearing loss can slow age-related cognitive decline. Cognitively impaired people with hearing loss who fail to commit to HA use tend to have lower cognitive measurement scores before HA fitting. HA use is generally more challenging as people age and their cognitive abilities decline. Therefore, it is desirable that HAs be used when hearing loss and dementia are in their early stages.

Abstract
Today, fitting bespoke hearing aids involves injecting silicone into patients' ears to produce ear canal molds. These are subsequently 3D scanned to create digital ear canal impressions. However, before digital impressions can be used they require a substantial amount of effort in manual 3D editing. In this article, we present computational methods to pre-process ear canal impressions. The aim is to create automation tools to assist the hearing aid design, manufacturing and fitting processes as well as normalizing anatomical data to assist the study of the outer ear canal's morphology. The methods include classifying the handedness of the impression into left and right ear types, orienting the geometries onto the same coordinate system sense, and removing extraneous artifacts introduced by the silicone mold. We investigate the use of convolutional neural networks for performing these semantic tasks and evaluate their accuracy using a dataset of 3000 ear canal impressions. The neural networks proved highly effective at performing these tasks with 95.8% adjusted accuracy in classification, 92.3% within 20° angular error in registration and 93.4% intersection over union in segmentation.

Abstract
OBJECTIVES Speech understanding is considered a bimodal and bidirectional process, whereby visual information (i.e., speechreading) and also cognitive functions (i.e., top-down processes) are involved. Therefore, the purpose of the present study is twofold: (1) to investigate the auditory (A), visual (V), and cognitive (C) abilities in normal-hearing individuals, hearing aid (HA) users, and cochlear implant (CI) users, and (2) to determine an auditory, visual, cognitive (AVC)-profile providing a comprehensive overview of a person's speech processing abilities, containing a broader variety of factors involved in speech understanding. DESIGN Three matched groups of subjects participated in this study: (1) 31 normal-hearing adults (mean age = 58.76), (2) 31 adults with moderate to severe hearing loss using HAs (mean age = 59.31), (3) 31 adults with a severe to profound hearing loss using a CI (mean age = 58.86). The audiological assessments consisted of pure-tone audiometry, speech audiometry in quiet and in noise. For evaluation of the (audio-) visual speech processing abilities, the Test for (Audio) Visual Speech perception was used. The cognitive test battery consisted of the letter-number sequencing task, the letter detection test, and an auditory Stroop test, measuring working memory and processing speed, selective attention, and cognitive flexibility and inhibition, respectively. Differences between the three groups were examined using a one-way analysis of variance or Kruskal-Wallis test, depending on the normality of the variables. Furthermore, a principal component analysis was conducted to determine the AVC-profile. RESULTS Normal-hearing individuals scored better for both auditory, and cognitive abilities compared to HA users and CI users, listening in a best aided condition. No significant differences were found for speech understanding in a visual condition, despite a larger audiovisual gain for the HA users and CI users. Furthermore, an AVC-profile was composed based on the different auditory, visual, and cognitive assessments. On the basis of that profile, it is possible to determine one comprehensive score for auditory, visual, and cognitive functioning. In the future, these scores could be used in auditory rehabilitation to determine specific strengths and weaknesses per individual patient for the different abilities related to the process of speech understanding in daily life. CONCLUSIONS It is suggested to evaluate individuals with hearing loss from a broader perspective, considering more than only the typical auditory abilities. Also, cognitive and visual abilities are important to take into account to have a more complete overview of the speech understanding abilities in daily life.

Surgical Outcomes of Modified Technique for Transcutaneous Bone Conduction Hearing Aid Implantation. Laryngoscope 2024; 134:2401-2404. [PMID: 38149671 DOI: 10.1002/lary.31244] [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: 08/03/2023] [Revised: 10/11/2023] [Accepted: 12/01/2023] [Indexed: 12/28/2023]
Abstract
OBJECTIVE To detail a modified surgical technique for implantation of the Osia 2 Bone Conduction Hearing Aid (BCHA) system and to assess intra- and postoperative outcomes of this technique. METHODS A retrospective review was performed for cases undergoing implantation of an Osia 2 BCHA at a tertiary academic medical center. Modifications were made to the surgical procedure including: horizontal or curvilinear incisions, placement of the osseointegrated screw slightly superior to the plane of the external auditory canal, and double layer wound closure. Data regarding outcomes including demographics, incision type, surgical time, drilling requirements, and complications were collected using the electronic medical record. RESULTS A total of twenty-eight cases were evaluated with 57.1% and 42.9% utilizing horizontal and curved incisions, respectively. The median age for recipients was 43.1 years with six pediatric cases included in the study. Median operative time was 58 min (43-126 min). The majority of cases required minimal (60.7%) or no drilling (28.6%) with a significant increase in operative time for those requiring moderate drilling versus minimal to no drilling (F = 8.02, p = 0.002). There were no intraoperative complications. One (3.6%) postoperative seroma occurred which resolved with conservative management. CONCLUSION The proposed modified surgical technique is a safe and effective method for implantation of the transcutaneous BCHA system with a low complication rate. Keys include incision design, implant placement, and two-layered closure to minimize wound tension. These modifications can improve ease of the procedure and reduce operative time. These techniques also appear to be applicable to the pediatric population. LEVEL OF EVIDENCE 3 Laryngoscope, 134:2401-2404, 2024.

Abstract
OBJECTIVES Hearing aid processing in realistic listening environments is difficult to study effectively. Often the environment is unpredictable or unknown, such as in wearable aid trials with subjective report by the wearer. Some laboratory experiments create listening environments to exert tight experimental control, but those environments are often limited by physical space, a small number of sound sources, or room absorptive properties. Simulation techniques bridge this gap by providing greater experimental control over listening environments, effectively bringing aspects of the real-world into the laboratory. This project used simulation to study the effects of wide-dynamic range compression (WDRC) and digital noise reduction (DNR) on speech intelligibility in a reverberant environment with six spatialized competing talkers. The primary objective of this study was to determine the efficacy of WDRC and DNR in a complex listening environment using virtual auditory space techniques. DESIGN Participants of greatest interest were listeners with hearing impairment. A group of listeners with clinically normal hearing was included to assess the effects of the simulation absent the complex effects of hearing loss. Virtual auditory space techniques were used to simulate a small restaurant listening environment with two different reverberation times (0.8 and 1.8 sec) in a range of signal to noise ratios (SNRs) (-8.5 to 11.5 dB SNR). Six spatialized competing talkers were included to further enhance realism. A hearing aid simulation was used to examine the degree to which speech intelligibility was affected by slow and fast WDRC in conjunction with the presence or absence of DNR. The WDRC and DNR settings were chosen to be reasonable estimates of hearing aids currently available to consumers. RESULTS A WDRC × DNR × Hearing Status interaction was observed, such that DNR was beneficial for speech intelligibility when combined with fast WDRC speeds, but DNR was detrimental to speech intelligibility when WDRC speeds were slow. The pattern of the WDRC × DNR interaction was observed for both listener groups. Significant main effects of reverberation time and SNR were observed, indicating better performance with lower reverberation times and more positive SNR. CONCLUSIONS DNR reduced low-amplitude noise before WDRC-amplified the low-intensity portions of the signal, negating one potential downside of fast WDRC and leading to an improvement in speech intelligibility in this simulation. These data suggest that, in some real-world environments that include both reverberation and noise, older listeners with hearing impairment may find speech to be more intelligible if DNR is activated when the hearing aid has fast compression time constants. Additional research is needed to determine the appropriate DNR strength and to confirm results in wearable hearing aids and a wider range of listening environments.

Remote or in-clinic? The effect of service delivery mode on hearing aid output: study protocol for a double-blinded, randomised trial in adults with mild to moderate sensorineural hearing loss. Trials 2024; 25:256. [PMID: 38610038 PMCID: PMC11010415 DOI: 10.1186/s13063-024-08068-y] [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: 06/05/2023] [Accepted: 03/20/2024] [Indexed: 04/14/2024] Open
Abstract
BACKGROUND Teleaudiology can potentially improve access to hearing healthcare services. Remote hearing aid fittings offer a new mode of service delivery that removes barriers of geography and access to an audiologist. Real-ear measurements (REMs) are the gold standard for hearing aid output verification but require in-clinic appointments. This study will investigate whether remote hearing aid fittings can provide clinically equivalent outcomes when compared to current, in-clinic, best practice guidelines. RESEARCH DESIGN A repeated measure, double-blinded crossover design will be used. Participants will be randomly allocated to one of two groups to determine order of intervention, balanced for degree of hearing loss. STUDY SAMPLE Sixty adults with mild to moderate hearing loss and at least 1 year of experience with hearing aids will be recruited. DATA COLLECTION AND ANALYSIS Participants will complete two hearing aid fitting protocols, one using an in-clinic fitting process and the other using a remote (at-home) fitting process. In-clinic fittings will include REMs with adjustments to standard (NAL-NL2) prescription targets. The two fitting protocols will then be randomly assigned to participants in a crossover design, so participants and researchers will be blinded to the order of the two fitting protocols. Participants will then have a 4-week period with follow-up appointments for participant-directed gain adjustment. For each fitting protocol, participants will complete objective measurements of final hearing aid output with REMs, speech-in-noise testing, subjective measurements of hearing aid performance, and quality of life measurements. They will then begin an identical period of living with, adjusting, and objective assessment with the other fitting protocol. Data will be analysed as repeated measures with statistical control for potential confounding variables. RESULTS Data will compare the four-frequency average real-ear aided response (4FREAR) for hearing aids programmed in-clinic and hearing aids programmed remotely, after participant-directed gain adjustments. Secondary measures will assess clinically significant differences in estimated speech intelligibility, hearing-related quality of life, hearing aid benefit, sound quality and preference, and speech-in-noise ability. CONCLUSIONS This study will inform the development of best practice guidelines for remote hearing aid fittings. If no clinically significant differences are found between in-clinic and remote fit hearing aids, it has the potential to expand teleaudiology initiatives.

Association of hearing loss with patient-reported functional outcomes in adult survivors of childhood cancer. J Natl Cancer Inst 2024; 116:596-605. [PMID: 38048603 PMCID: PMC10995849 DOI: 10.1093/jnci/djad250] [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: 09/01/2023] [Revised: 11/13/2023] [Accepted: 11/27/2023] [Indexed: 12/06/2023] Open
Abstract
BACKGROUND Hearing loss is prevalent following ototoxic therapy for childhood cancer. Associations between hearing loss, self-perceived hearing handicap, and functional outcomes have not been examined in survivors. METHODS Adult survivors treated with platinum or head and neck radiotherapy with hearing loss were recruited. A total of 237 survivors (median age at survey = 37.0 years [range = 30.0-45.0 years]; median = 29.1 years [range = 22.4-35.0 years] since diagnosis; median = 4.0 years [range = 2.9-7.7 years] from last audiogram to survey) completed the Hearing Handicap Inventory for Adults and questionnaires on social and emotional functioning and hearing aid use. Hearing loss severity was defined according to Chang criteria. Multivariable logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs) for associations between hearing loss, hearing handicap, functional outcomes, and hearing aid use with adjustment for sex, race, age at hearing loss diagnosis, and age at survey. RESULTS Two-thirds of survivors had severe hearing loss, which was associated with increased likelihood of hearing handicap (mild-moderate handicap: OR = 2.72, 95% CI = 1.35 to 5.47; severe handicap: OR = 5.99, 95% CI = 2.72 to 13.18). Survivors with severe hearing handicap had an increased likelihood of social isolation (OR = 8.76, 95% CI = 3.62 to 21.20), depression (OR = 9.11, 95% CI = 3.46 to 24.02), anxiety (OR = 17.57, 95% CI = 3.77 to 81.84), reduced personal income (OR = 2.82, 95% CI = 1.46 to 5.43), and less than full-time employment (OR = 2.47, 95% CI = 1.30 to 4.70). Survivors who did not use a recommended hearing aid were twice as likely to have less than full-time employment (OR = 2.26, 95% CI = 1.10 to 4.61) and reduced personal income (OR = 2.24, 95% CI = 1.08 to 4.63) compared with survivors who wore a hearing aid. CONCLUSION Self-perceived hearing handicap beyond measured hearing loss is associated with reduced functional outcomes. Assessment of hearing handicap may facilitate targeted interventions in adult survivors with hearing loss.

Abstract
Hearing is critical to spoken language, cognitive, and social development. Little is known about how early auditory experiences impact the brain structure of children with bilateral sensorineural hearing loss. This study examined the influence of hearing aid use and residual hearing on the auditory cortex of children with severe to profound congenital sensorineural hearing loss. We evaluated cortical preservation in 103 young pediatric cochlear implant candidates (55 females and 48 males) by comparing their multivoxel pattern similarity of auditory cortical structure with that of 78 age-matched children with typical hearing. The results demonstrated that early-stage hearing aid use preserved the auditory cortex of children with bilateral congenital sensorineural hearing loss. Children with less residual hearing experienced a more pronounced advantage from hearing aid use. However, this beneficial effect gradually diminished after 17 months of hearing aid use. These findings support timely fitting of hearing aids in conjunction with early implantation to take advantage of neural preservation to maximize auditory and spoken language development.

Abstract
OBJECTIVE This review aims to quantify the pooled functional gain (FG) in different types of hearing loss with the transcutaneous hearing device, Osia (Cochlear, Sydney, Australia) in comparison with the unaided state. Secondary outcomes are patient-reported outcomes measures (PROMs) and complication rates. DATA SOURCES Medline, Embase, SCOPUS, Cochrane CENTRAL, PROSPERO and Cochrane Library. REVIEW METHODS Systematic review and meta-analysis of indexed search terms relating to "Osia," "Osseointegration," "Cochlear Implant," and "Bone-Anchored Prosthesis" was performed from database inception to September 20, 2022. RESULTS Of the 168 studies identified, 14 studies with 15 patient cohorts (n = 314) met inclusion criteria for meta-analysis. Pooled overall mean FG for all types of hearing loss was 35.0 dB sound pressure level (SPL) (95% confidence interval [CI] 29.12-40.97) compared against unaided hearing. Pooled FG for conductive/mixed hearing loss was 37.7 dB SPL (95% CI 26.1-49.3). Pooled single-sided deafness (SSD) FG could not be calculated due to the small patient cohort for whom SSD data was reported. There is a trend toward improvements in speech receptiveness threshold, signal to noise ratio, and some PROMs compared with baseline hearing. Early complication rates demonstrate risks similar to other transcutaneous implants, with a low predicted explantation (0.11%, 95% CI 0.00%-1.90%) and wound infection rate (1.92% [95% CI 0.00%-6.17%]). No articles directly comparing transcutaneous devices were identified. CONCLUSION The Osia devices demonstrate clear audiologic benefits and a good safety profile for the included patient population. Our study results indicate that frequency-specific gain, PROMs, and the audiological benefit in single-sided deafness may be areas for future prospective research. Laryngoscope, 134:1531-1539, 2024.

Abstract
Objective To determine the benefits of binaural hearing rehabilitation in patients with monaural conductive or mixed hearing loss treated with a unilateral bone conduction implant (BCI). Methods This monocentric study includes 7 patients with monaural conductive or mixed hearing loss who underwent surgical implantation of a unilateral BCI (Bonebridge, Med-El). An ITA Matrix test was performed by each patient included in the study - without and with the BCI and in three different settings - to determine the summation effect, squelch effect and head shadow effect. Subjective hearing benefits were assessed using the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire. Results The difference in signal to noise ratio of patients without and with BCI was 0.79 dB in the summation setting (p < 0.05), 4.62 dB in the head shadow setting (p < 0.05) and 1.53 dB (p = 0.063) in the squelch setting. The APHAB questionnaire revealed a subjective discomfort in the presence of unexpected sounds in patients using a unilateral BCI (aversiveness score) compared to the same environmental situations without BCI, with a mean discomfort score of 69.00% (SD ± 21.24%) with monaural BCI versus 25.67% (SD ± 16.70%) without BCI (difference: -43.33%, p < 0.05). In terms of global score, patients wearing a unilateral Bonebridge implant did not show any significant differences compared to those without hearing aid (difference: -4.00%, p = 0.310). Conclusions Our study shows that the use of a unilateral BCI in patients affected by monaural conductive or mixed hearing loss can improve speech perception under noise conditions due to the summation effect and to the decrease of the head shadow effect. However, since monaural BCIs might lead to discomfort under noise conditions in some subjects, a pre-operative assessment of the possible individual benefit of a monaural BCI should be carried out in patients affected by unilateral conductive or mixed hearing loss in order to investigate the possible additional effect of the fitting of hearing aids.

Abstract
BACKGROUND Deaf and hard of hearing (DHH) children may experience communication delays, irrespective of early intervention and technology. Australian Sign Language (Auslan) is one approach in early intervention to address language delays. Current prevalence of Auslan use among Australian families with DHH children is unknown. AIMS The first aim was to determine the proportion of families enrolled in an Australian statewide hearing loss databank who use Auslan with their DHH child. The second aim was to explore the relationships between indicators of child hearing loss (bilateral or unilateral hearing loss, degree of hearing loss, and device use: hearing aids and cochlear implants), family factors (maternal education, attendance at early intervention, family history of deafness, and socio-economic disadvantage) and the family's reported use of Auslan. METHODS We analysed the enrolment data from 997 families who participated in an Australian statewide hearing loss databank between 2012 and 2021. We described the proportion of families who used Auslan with their DHH child at home. The association between indicators of child hearing loss and family factors, and the parental reports of communication approach were examined using correlation analyses. RESULTS Eighty-seven of 997 parents (8.7%) reported using Auslan with their DHH child. Of these, 26 (2.6%) used Auslan as their primary language. The use of Auslan at home was associated with the following indicators of child hearing loss: bilateral hearing loss, profound compared to mild hearing loss, and cochlear implant and hearing aid use compared to no device use. The family factors associated with the use of Auslan were: referral or attendance at early intervention compared to those who did not attend, and a family history of deafness compared to those with none. No association was found between maternal education and socio-economic disadvantage and the use of Auslan. CONCLUSION This Australian study found a low proportion (8.7%) of families with a DHH child who reported using Auslan. Seven child hearing loss and family factors were considered, and five were significantly associated with using Auslan at home. Children with a greater degree of hearing loss, attendance at early intervention and family history of deafness tended to use Auslan.

Abstract
PURPOSE Remote microphone systems improve intelligibility in difficult conditions when the performance of hearing aids/cochlear implants is insufficient. The purpose of this study was to explore parents' experiences with remote microphone systems for their children with hearing loss and to determine the advantages and disadvantages as perceived by parents. MATERIALS AND METHODS Data were collected by means of semi-structured interviews with parents of children with moderate to profound bilateral hearing loss (2-19 years old). The open coding method and thematic analysis were used. The final sample consisted of 19 mothers and 9 fathers who had experience with remote microphone systems. RESULTS Parents listed the advantages of remote microphone systems for their child, for themselves and for other carers, such as better hearing and understanding, a life more similar to that of their peers without hearing loss, safety in road traffic, lower fatigue, vocabulary acquisition, better school results. Some limitations were identified, namely low benefits, technical issues and a reluctance to use the device by children or teachers. CONCLUSIONS It is crucial to provide parents with information about assistive devices and the consequences of limited access to hearing speech. Professionals should motivate parents, children and teachers to use remote microphone systems even in situations when the benefit may not be obvious if there is a potential benefit for the child. IMPLICATIONS FOR REHABILITATIONThe main advantages of remote microphone systems perceived by parents are better hearing and understanding, a life more similar to peers without hearing loss, safety in traffic, lower fatigue, vocabulary acquisition and better school results.The main disadvantages are for parents: persisting hearing problems, low benefits, technical issues and a reluctance to use the device by children or teachers.Sufficient and accurate information is needed about remote microphone systems, but also about the consequences of hearing loss in general.The possibility to try wireless devices before buying and troubleshooting help is appreciated.

Abstract
OBJECTIVE The Baha SoundArc coupling system has been developed as a non-surgical coupling of a Baha sound processor to the skull allowing the transfer of vibrational energy to the cochlear partition via bone conduction pathways. Today, there are several alternatives to this non-surgical approach as the Baha headband/test band, or the Baha Softband, or adhesive patches. Each of these current options have benefits and liabilities. The aim of the study was to evaluate pediatric experience and performance when using two non-surgical options, the Baha SoundArc compared to the Baha Softband. METHODS Twenty-five children with unilateral mixed or conductive hearing loss aged 5-12 years of age evaluated the use of the Baha SoundArc compared to their existing Baha Softband in a one month take home trial. Participants had a minimum of 3 months experience using the control, Baha Softband. Participants were assessed at baseline and one month following fit of the Baha SoundArc. Measures included an experience and use patient reported outcome, speech perception testing in quiet using Phonetically Balanced Kindergarten (PBK) words, and sound field audiometry. RESULTS Mean aided soundfield thresholds across the frequency range were 27.6 dB HL for Softband and 26.0 dB HL for SoundArc, which were not significantly different (P = >.05). Mean word recognition score was 80.8% when aided with the Softband device and 85.1% with the SoundArc, which was also not significantly different (P = >.05). Most children favored the aesthetics and usability of the SoundArc over Softband, but comfort ratings were largely similar for both devices. CONCLUSIONS Bone conduction sound processors mounted on a SoundArc or a Softband resulted in comparable improvements in aided thresholds and speech understanding in children suffering from conductive or mixed hearing loss. Both wearing modalities can be considered equivalent in terms of audiological outcomes, although both patients and clinicians preferred the usability and aesthetics of the SoundArc. The SoundArc provides an alternative wearing option for patients that may otherwise be discouraged by the aesthetics and usability of the Softband device. CLINICALTRIALS GOV IDENTIFIER NCT03333577.

Abstract
Objectives. To produce a database of private insurance hearing aid mandates in the United States and quantify the share of privately insured individuals covered by a mandate. Methods. We used health-related policy surveillance methods to create a database of private insurance hearing aid mandates through January 2023. We coded salient features of mandates and combined policy data with American Community Survey and Medicare Expenditure Panel Survey-Insurance Component data to estimate the share of privately insured US residents covered by a mandate from 2008 to 2022. Results. A total of 26 states and 1 territory had private insurance hearing aid mandates. We found variability for mandate exceptions, maximum age eligibility, allowable frequency of benefit use, and coverage amounts. Between 2008 and 2022 the proportion of privately insured youths (aged ≤ 18 years) living where there was a private insurance hearing aid mandate increased from 3.4% to 18.7% and the proportion of privately insured adults (19-64 years) increased from 0.3% to 4.6%. Conclusions. Hearing aid mandates cover a small share of US residents. Mandate exceptions in several states limit coverage, particularly for adults. Public Health Implications. A federal mandate would improve hearing aid access. States can also improve access by adopting exception-free mandates with limited utilization management and no age restrictions.

Evaluating Listening Effort in Unilateral, Bimodal, and Bilateral Cochlear Implant Users. Otolaryngol Head Neck Surg 2024; 170:1147-1157. [PMID: 38104319 DOI: 10.1002/ohn.609] [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: 08/03/2023] [Revised: 10/24/2023] [Accepted: 11/24/2023] [Indexed: 12/19/2023]
Abstract
OBJECTIVE Evaluate listening effort (LE) in unilateral, bilateral, and bimodal cochlear implant (CI) users. Establish an easy-to-implement task of LE that could be useful for clinical decision making. STUDY DESIGN Prospective cohort study. SETTING Tertiary neurotology center. METHODS The Sentence Final Word Identification and Recall Task, an established measure of LE, was modified to include challenging listening conditions (multitalker babble, gender, and emotional variation; test), in addition to single-talker sentences (control). Participants listened to lists of sentences in each condition and recalled the last word of each sentence. LE was quantified by percentage of words correctly recalled and was compared across conditions, across CI groups, and within subjects (best aided vs monaural). RESULTS A total of 24 adults between the ages of 37 and 82 years enrolled, including 4 unilateral CI users (CI), 10 bilateral CI users (CICI), and 10 bimodal CI users (CIHA). Task condition impacted LE (P < .001), but hearing configuration and listener group did not (P = .90). Working memory capacity and contralateral hearing contributed to individual performance. CONCLUSION This study adds to the growing body of literature on LE in challenging listening conditions for CI users and demonstrates feasibility of a simple behavioral task that could be implemented clinically to assess LE. This study also highlights the potential benefits of bimodal hearing and individual hearing and cognitive factors in understanding individual differences in performance, which will be evaluated through further research.

The impact of head-worn devices in an auditory-aided visual search task. THE JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA 2024; 155:2460-2469.

Abstract
Head-worn devices (HWDs) interfere with the natural transmission of sound from the source to the ears of the listener, worsening their localization abilities. The localization errors introduced by HWDs have been mostly studied in static scenarios, but these errors are reduced if head movements are allowed. We studied the effect of 12 HWDs on an auditory-cued visual search task, where head movements were not restricted. In this task, a visual target had to be identified in a three-dimensional space with the help of an acoustic stimulus emitted from the same location as the visual target. The results showed an increase in the search time caused by the HWDs. Acoustic measurements of a dummy head wearing the studied HWDs showed evidence of impaired localization cues, which were used to estimate the perceived localization errors using computational auditory models of static localization. These models were able to explain the search-time differences in the perceptual task, showing the influence of quadrant errors in the auditory-aided visual search task. These results indicate that HWDs have an impact on sound-source localization even when head movements are possible, which may compromise the safety and the quality of experience of the wearer.

Abstract
OBJECTIVE To conduct the first phases in the development of a self-report measure of empowerment on the hearing health journey, specifically, item generation and content evaluation of the initial pool of items generated. DESIGN A content expert panel survey and cognitive interviews were conducted. Descriptive statistics were obtained for the quantitative data, and the cognitive interviews were analysed using thematic analysis. STUDY SAMPLE Eleven researchers and clinicians participated in the content expert surveys. Sixteen experienced hearing aid users participated in the cognitive interviews, recruited from the USA and Australia. RESULTS The items underwent five iterations based on feedback from the survey and interview data. This resulted in a set of 33 quality-tested potential survey items that were rated highly for relevance (mean = 3.96), clarity (mean = 3.70) and fit to dimensions of empowerment (mean = 3.92) (scale 0-4, where 4 was the maximum rating). CONCLUSIONS Involving stakeholders in item generation and content evaluation increased relevance, clarity, fit to dimension, comprehensiveness, and acceptability of the items. This preliminary version of the 33-item measure underwent further psychometric refinement (Rasch analysis and traditional classical test theory testing) to validate it for clinical and research use (reported separately).

Abstract
PURPOSE In patients with unilateral sensorineural hearing loss (USNHL), we explored both objective functional audiological gains and subjective satisfaction, indicating when a unilateral hearing aid is valuable. METHODS Thirty-seven patients with mild-to-moderate USNHL (mean pure-tone thresholds between 25 and 70 dB) were prescribed unilateral hearing aids. Functional gain, the aided speech discrimination score (SDS), the Hearing in Noise Test (HINT) score, and the sound localization test score were collected, and a questionnaire (the Hearing Handicap Inventory for the Elderly, HHIE) completed after 1, 2, and 3 months of hearing aid use. We classified the participants as having 'no handicap' (HHIE < 17), 'mild-to-moderate handicap' (17-42), and 'significant handicap' (> 42). RESULTS The decrease in handicap afforded by unilateral hearing aids was largest in the 'significant handicap' group (the HHIE total score fell from 59.1 to 37.2; P = 0.007). There were no between-group differences in either functional gain or the aided SDS. Only the 'significant handicap' group evidenced an improved HINT score; the composite signal-to-noise ratio (SNR) fell from - 1.5 to - 2.2 dB [S/N] (P = 0.023). The HHIE usefully indicated when a hearing aid alleviated the discomfort of USNHL; patients with unaided HHIE scores ≥ 20 evidenced significant decreases in the composite SNR (- 1.7 to - 2.0 dB [S/N]; P = 0.045). CONCLUSIONS When considering whether to prescribe a unilateral hearing aid for patients with mild-to-moderate USNHL, it is helpful to use the HHIE to evaluate discomfort. If the total score is ≥ 20, a hearing aid is appropriate.

Abstract
Hearing loss affects some nutrient intake. Disabling hearing loss may exacerbate these issues. We aimed to evaluate nutrient intake and assess deficiencies based on functional hearing status. The study included 6907 participants with information on demographic factors, nutrient intake, weight, height, disease status, and hearing level in the eighth Korea National Health and Nutrition Examination Survey, conducted from 2019 to 2021. We categorized the participants into 3 groups based on their functional hearing status: bilateral hearing, unilateral hearing, and disabling hearing loss. The disabling hearing loss group showed lower intake of most major nutrients (P < 0.05), dietary fiber (P < 0.001), and most minerals and vitamins (P < 0.05), with some insufficiencies. The unilateral hearing group showed lower intake only for potassium (P = 0.036) compared to the bilateral hearing group and significantly higher intake of hydration (P = 0.039), dietary fiber (P = 0.039), and calcium (P = 0.009) than the disabling hearing loss group. Nutrient insufficiency in the disabling hearing loss group was more prominent in women, and was partially resolved by using hearing aids. Clinicians and nutritionists should consider undernourishment in these patients, and appropriate interventions for nutrition and hearing aids should be recommended.

Abstract
COVID - 19 (Corona Virus Infectious Disease) situations reported in 2019, declared by World Health Organization (WHO) as a pandemic is still a prevailing global crisis. Common regulations were implemented such as lockdown, wearing face masks as mandatory, face shields, gloves and maintaining physical and social distance in public places to reduce the spread of the virus. These pandemic induced challenges affected social communication, technical and behavioral aspects in lifestyle of people with hearing impairment. Along with medical, paramedical services, the crisis had challenged hearing, speech language pathology and therapy services too. The study aimed to explore the challenges that adults with hearing impairment had experienced during the pandemic and to suggest some practical solutions that can be implemented by audiologists. It is a questionnaire-based study with purposive sampling method employed in data collection. The questionnaire was administered on adult hearing aid users (mean age: 18 years) recruited for participation from different parts/ clinical setups across India. The outcome of the questionnaire did support the assumption that availing audiological services was difficult or impossible for most of the hearing aid users. Accessing batteries was reported to be the most frequent issue. Adequate level of hearing though hearing aid was important to them and clinical services could not be availed for long period of time due to travel related issues and closure of audiological services. Also, social isolation impacted on their quality of life and effective communication. As a possible solution most of the users chose tele services as a better solution.

Abstract
This methodological study aimed to assess the validity and reliability of the Turkish version of the Evaluation of the Impact of Hearing Loss in Adults (ERSA) questionnaire for individuals with treated hearing loss. The study involved 200 participants, and both exploratory factor analysis and confirmatory factor analysis were used to examine structural validity. External validity was assessed by correlating ERSA scores with the Abbreviated Profile of Hearing Aid Benefit (APHAB). Internal consistency and test-retest reliability were evaluated using Cronbach's alpha and the intraclass correlation coefficient, respectively. The Turkish ERSA demonstrated strong psychometric properties, with significant correlations between APHAB and ERSA scores and excellent internal consistency and test-retest reliability. The findings suggest that the Turkish ERSA is a valid and reliable tool for evaluating the impact of hearing loss in individuals.

Abstract
The prevalence of hearing loss is high among older adults; globally, 65% of adults over 60 years have hearing loss. Over the past decade, evidence from epidemiologic studies has linked hearing loss to nearly two times greater risk of dementia. The hypothesized mechanistic pathways through which hearing loss could contribute to increased dementia risk include the effects of hearing on greater cognitive load, changes in brain structure and function, and decreased social engagement. These mechanistic pathways may be modified by management of hearing loss using existing intervention (eg, hearing aids). Hearing treatment may be an effective intervention for slowing cognitive decline in some older adults. In this review, we update existing reviews of the current epidemiologic research on the association between hearing loss and dementia risk and discuss hypothesized mechanisms of this association. We also discuss management of hearing loss as a potential intervention for slowing cognitive decline and reducing dementia risk.

Role of early hearing aid experience in speech recognition in patients with bilateral congenital microtia following Bonebridge implantation: a retrospective cohort study. Eur Arch Otorhinolaryngol 2024; 281:1205-1214.

Abstract
PURPOSE To identify audiological and demographic variables that predict speech recognition abilities in patients with bilateral microtia who underwent Bonebridge (BB) implantation. METHODS Fifty patients with bilateral microtia and bilateral conductive hearing loss (CHL) who underwent BB implantation were included. Demographic data, preoperative hearing aid use experience, and audiological outcomes (including pure-tone hearing threshold, sound field hearing threshold [SFHT], and speech recognition ability) for each participant were obtained. The Chinese-Mandarin Speech Test Materials were used to test speech recognition ability. The word recognition score (WRS) of disyllabic words at 65 dB SPL signals was measured before and after BB implantation in quiet and noisy conditions. RESULTS The mean preoperative WRS under quiet and noisy conditions was 10.44 ± 12.73% and 5.90 ± 8.76%, which was significantly improved to 86.38 ± 9.03% and 80.70 ± 11.34%, respectively, following BB fitting. Multiple linear regression analysis revealed that lower preoperative SFHT suggested higher preoperative WRS under both quiet and noisy conditions. Higher age at implantation predicted higher preoperative WRS under quiet conditions. Furthermore, patients with more preoperative hearing aid experience and lower postoperative SFHT were more likely to have higher postoperative WRS under both quiet and noisy testing conditions. CONCLUSIONS This study represents the first attempt to identify predictors of preoperative and postoperative speech recognition abilities in patients with bilateral microtia with BB implantation. These findings emphasize that early hearing intervention before implantation surgery, combined with appropriate postoperative fitting, contributes to optimal benefits in terms of postoperative speech recognition ability.

Abstract
BACKGROUND The aim of this study is to examine the relationship between behavioral speech-in-noise listening tasks and self-reported speech-in-noise outcomes of hearing aid user adult listeners. METHOD To measure the self-reported outcomes of hearing, the Hearing Handicap Inventory for Adults [HHI-A], Speech, Spatial and Qualities of Hearing Scale (SSQ) and Amsterdam Inventory for Auditory Disability and Handicap were employed. To screen the cognitive abilities, Montreal Cognitive Assessment (MoCA) tool was used. Turkish matrix sentence test (TMST) was used for speech-in-noise test. Eighteen adult hearing aid users (mean age of 36.6 years) were participated. CONCLUSIONS Results showed that some self-reported listening-in-noise outcomes are correlated with lab-based measurements of speech-in-noise test scores but not with the aided speech intelligibility thresholds. Given the present limitations of relying solely on self-report measures, it is important to complement them with objective measures to ensure a comprehensive evaluation.

Abstract
BACKGROUND AND OBJECTIVES The ability to localize sounds is partly recovered in patients using a cochlear implant (CI) in one ear and a hearing aid (HA) on the contralateral side. Binaural processing seems effective at least to some extent, despite the difference between electric and acoustic stimulation in each ear. To obtain further insights into the mechanisms of binaural hearing in these listeners, localization of low- and high-frequency sounds was tested. STUDY DESIGN The study used a within-subject design, where participants were tasked with localizing sound sources in the horizontal plane. The experiment was conducted in an anechoic chamber, where an array of seven loudspeakers was mounted along the 24 azimuthal angle span from -90° to +90°. Stimuli were applied with different frequencies: broadband noise and high- and low-frequency noise. SUBJECTS Ten CI recipients participated in the study. All had an asymmetric hearing loss with a CI in the poorer ear and an HA on the contralateral side. MAIN OUTCOME MEASURES Accuracy of sound localization in terms of angular error and percentage of correct localization scores. RESULTS The median angular error was 40° in bimodal conditions for both broadband noise and high-frequency noise stimuli. The angular error increased to 47° for low-frequency noise stimuli. In the unilaterally aided condition with an HA, only a median angular error of 78° was observed. CONCLUSIONS Irrespective of the frequency composition of the stimuli, this group of bimodal listeners showed some ability to localize sounds. Angular errors were larger than those reported in the literature for bilateral CI users or single-sided deaf listeners with a CI. In the unilateral listening condition with HA, only localization of sounds was not possible for most subjects.

Abstract
OBJECTIVE To compare quality of life (QOL) outcomes of percutaneous and transcutaneous bone conduction devices (pBCD and tBCD, respectively). DATABASES REVIEWED Pubmed, Scopus, CINAHL. METHODS A systematic review was performed searching for English language articles from inception to March 15, 2023. Studies reporting QOL outcomes measured using a validated tool following implantation of either pBCDs or tBCDs were considered for inclusion. QOL outcomes included scores for Glasgow Benefit Inventory, Glasgow Children's Benefit Inventory, Abbreviated Profile of Hearing Aid Benefit, and the Speech, Spatial, and Qualities of Hearing Scale. A meta-analysis of continuous measures was performed. RESULTS A total of 52 articles with 1,469 patients were included. Six hundred eighty-nine patients were implanted with pBCDs, and the remaining 780 were implanted with tBCDs. Average Glasgow Benefit Inventory scores for the tBCD group (33.0, 95% confidence interval [22.7-43.3]) were significantly higher than the pBCD group (30.9 [25.2-36.6]) (Δ2.1 [1.4-2.8], p < 0.0001). Mean Glasgow Children's Benefit Inventory scores (Δ3.9 [2.0-5.8], p = 0.0001) and mean gain in Abbreviated Profile of Hearing Aid Benefit scores (Δ5.6 [4.8-6.4], p < 0.0001) were significantly higher among patients implanted with tBCDs than those implanted with pBCDs. Patients implanted with tBCDs also had significantly higher gains on the Speech (Δ1.1 [0.9-1.3], p < 0.0001), Spatial (Δ0.8 [0.7-0.9], p < 0.0001), and Qualities of Hearing (Δ1.2 [1.1-1.3], p < 0.0001) portions of the Speech, Spatial, and Qualities of Hearing Scale than those implanted with pBCDs. CONCLUSIONS Patients implanted with transcutaneous devices had better QOL outcomes than those implanted with percutaneous devices.

Abstract
Spectro-temporal modulation (STM) detection sensitivity has been shown to be associated with speech-in-noise reception in hearing-impaired (HI) individuals. Based on previous research, a recent study [Zaar, Simonsen, Dau, and Laugesen (2023). Hear Res 427:108650] introduced an STM test paradigm with audibility compensation, employing STM stimulus variants using noise and complex tones as carrier signals. The study demonstrated that the test was suitable for the target population of elderly individuals with moderate-to-severe hearing loss and showed promising predictions of speech-reception thresholds (SRTs) measured in a realistic set up with spatially distributed speech and noise maskers and linear audibility compensation. The present study further investigated the suggested STM test with respect to (i) test-retest variability for the most promising STM stimulus variants, (ii) its predictive power with respect to realistic speech-in-noise reception with non-linear hearing-aid amplification, (iii) its connection to effects of directionality and noise reduction (DIR+NR) hearing-aid processing, and (iv) its relation to DIR+NR preference. Thirty elderly HI participants were tested in a combined laboratory and field study, collecting STM thresholds with a complex-tone based and a noise-based STM stimulus design, SRTs with spatially distributed speech and noise maskers using hearing aids with non-linear amplification and two different levels of DIR+NR, as well as subjective reports and preference ratings obtained in two field periods with the two DIR+NR hearing-aid settings. The results indicate that the noise-carrier based STM test variant (i) showed optimal test-retest properties, (ii) yielded a highly significant correlation with SRTs (R2=0.61) exceeding and complementing the predictive power of the audiogram, (iii) yielded significant correlation (R2=0.51) with the DIR+NR-induced SRT benefit, and (iv) did not provide significant correlation with subjective preference for DIR+NR settings in the field. Overall, the suggested STM test represents a valuable tool for diagnosing speech-reception problems that remain when hearing-aid amplification has been provided and the resulting need for and benefit from DIR+NR hearing-aid processing.

CROS or hearing aid? Selecting the ideal solution for unilateral CI patients with limited aidable hearing in the contralateral ear. PLoS One 2024; 19:e0293811. [PMID: 38394286 PMCID: PMC10890777 DOI: 10.1371/journal.pone.0293811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Accepted: 10/19/2023] [Indexed: 02/25/2024] Open
Abstract
A hearing aid or a contralateral routing of signal device are options for unilateral cochlear implant listeners with limited hearing in the unimplanted ear; however, it is uncertain which device provides greater benefit beyond unilateral listening alone. Eighteen unilateral cochlear implant listeners participated in this prospective, within-participants, repeated measures study. Participants were tested with the cochlear implant alone, cochlear implant + hearing aid, and cochlear implant + contralateral routing of signal device configurations with a one-month take-home period between each in-person visit. Audiograms, speech perception in noise, and lateralization were evaluated. Subjective feedback was obtained via questionnaires. Marked improvement in speech in noise and non-implanted ear lateralization accuracy were observed with the addition of a contralateral hearing aid. There were no significant differences in speech recognition between listening configurations. However, the chronic device use questionnaires and the final device selection showed a clear preference for the hearing aid in spatial awareness and communication domains. Individuals with limited hearing in their unimplanted ears demonstrate significant improvement with the addition of a contralateral device. Subjective questionnaires somewhat contrast with clinic-based outcome measures, highlighting the delicate decision-making process involved in clinically advising one device or another to maximize communication benefits.

Outcomes and device use in children with bone-conduction hearing devices in South Africa. SOUTH AFRICAN JOURNAL OF COMMUNICATION DISORDERS 2024; 71:e1-e8. [PMID: 38426736 PMCID: PMC10913003 DOI: 10.4102/sajcd.v71i1.1005] [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: 08/01/2023] [Revised: 10/16/2023] [Accepted: 10/16/2023] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND Bone-conduction hearing devices (BCHD) can provide hearing solutions in settings where middle ear pathology is rife. OBJECTIVES Describe functional hearing outcomes and device use of children fitted with BCHD. METHOD Retrospective review of 79 children fitted with BCHD between January 2017 and May 2022. Outcomes included device use and subjective reports measured with the Parents' Evaluation of Aural/Oral Performance of Children (PEACH) and the Teachers' Evaluation of Aural/Oral Performance of Children (TEACH). Analysis of variance established association between mean data logging and type and degree of hearing loss. Thematic analyses were done for qualitative outcomes. RESULTS Average usage was 7.0 h/day (5.4 SD; range 0.1-24). PEACH ratings indicated 93.3% of children wore their BCHD 'always' or 'often', with 80% displaying Typical auditory performance at 1-month follow-up. TEACH ratings indicated 84.2% of children wore their BCHD 'always' or 'often', with 78.9% showing typical auditory behaviour. Increased usage was noted for conductive, mixed, moderate and severe hearing losses. There was a mean delay of 17.2 months (23.4 SD; range 0-90) between age of diagnosis and fitting. Thematic analyses identified two main themes: advantages and barriers to BCDH use. CONCLUSION Average device use fell short of the internationally recommended 10 h/day. Higher BCHD use was associated with higher functional listening performance scores. Long waiting times for medical or surgical intervention for conductive hearing losses can delay BCHD fitting.Contribution: Limited information is available to examine outcomes in children fitted with BCHD.

Prevalence and predictors of self-reported hearing aid use and benefit in Norway: the HUNT study. BMC Public Health 2024; 24:474. [PMID: 38355451 PMCID: PMC10867996 DOI: 10.1186/s12889-024-17852-z] [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: 10/11/2023] [Accepted: 01/23/2024] [Indexed: 02/16/2024] Open
Abstract
BACKGROUND Knowledge on hearing aid use and benefit is important to ensure appropriate and effective treatment. We aimed to assess prevalence and predictors of hearing aid use and benefit in Norway, as well as possible birth cohort changes. METHODS We analyzed two large cross-sectional, population-based hearing surveys of 63,182 adults in 1996-1998 and 2017-2019 (the HUNT study). We used multivariable regression models to examine independent predictors of hearing aid use and benefit, including demography, hearing-related variables, known risk factors for hearing loss and birth cohort. RESULTS The nationally weighted hearing aid use in the adult population increased from 4.2% in 1997 to 5.8% in 2018. The use among individuals with disabling hearing loss (≥ 35 dB HL) increased from 46.3% to 64.4%. Most users reported some (47%) or great (48%) help from their hearing aids. In addition to the level of hearing loss and birth cohort, factors associated with hearing aid use included lower age, tinnitus, childhood-onset hearing loss, higher education, marriage, having children, being exposed to occupational noise or impulse noise, recurrent ear infections, and head injury. In addition to the level of hearing loss, factors related to hearing aid benefit included younger age, female gender, and higher income. Being bothered by tinnitus reduced the benefit. CONCLUSION Our study shows an increase in self-reported hearing aid usage over time in Norway, with lower adoption rates and perceived benefits observed among the elderly. The results suggest that having a spouse and children positively influences the adoption of hearing aids. These findings emphasize the necessity of customized strategies to address demographic disparities and the need for innovative enhancements in hearing rehabilitation programs.
