Abstract
Comprehending the teacher's message when other students are chatting is challenging. Even though the sound environment is the same for a whole class, differences in individual performance can be observed, which might depend on a variety of personal factors and their specific interaction with the listening condition. This study was designed to explore the role of individual characteristics (reading comprehension, inhibitory control, noise sensitivity) when primary school children perform a listening comprehension task in the presence of a two-talker masker. The results indicated that this type of noise impairs children's accuracy, effort, and motivation during the task. Its specific impact depended on the level and was modulated by the child's characteristics. In particular, reading comprehension was found to support task accuracy, whereas inhibitory control moderated the effect of listening condition on the two measures of listening effort included in the study (response time and self-ratings), even though with a different pattern of association. A moderation effect of noise sensitivity on perceived listening effort was also observed. Understanding the relationship between individual characteristics and classroom sound environment has practical implications for the acoustic design of spaces promoting students' well-being, and supporting their learning performance.

Abstract
Mild cognitive impairment (MCI) commonly results in more rapid cognitive and behavioral declines than typical aging. Individuals with MCI can exhibit impaired receptive speech abilities that may reflect neurophysiological changes in auditory-sensory processing prior to usual cognitive deficits. Benefits from current interventions targeting communication difficulties in MCI are limited. Yet, neuroplasticity associated with musical experience has been implicated in improving neural representations of speech and offsetting age-related declines in perception. Here, we asked whether these experience-dependent effects of musical experience might extend to aberrant aging and offer some degree of cognitive protection against MCI. During a vowel categorization task, we recorded single-channel electroencephalograms (EEGs) in older adults with putative MCI to evaluate speech encoding across subcortical and cortical levels of the auditory system. Critically, listeners varied in their duration of formal musical experience (0-21 years). Musical experience sharpened temporal precision in auditory cortical responses, suggesting that musical experience produces more efficient processing of acoustic features by counteracting age-related neural delays. Additionally, robustness of brainstem responses predicted the severity of cognitive decline, suggesting that early speech representations are sensitive to preclinical stages of cognitive impairment. Our results extend prior studies by demonstrating positive benefits of musical experience in older adults with emergent cognitive impairments.

Abstract
Research into the potential associations between tinnitus and cognition has investigated specific cognitive domains in laboratory settings despite adults with tinnitus reporting broad cognitive difficulties in every-day life. To address this limitation, the present study compared performance and perceived exertion on a visual office-like task in 38 adults with tinnitus (19 with normal hearing and 19 with hearing loss) and 38 adults without tinnitus (19 with normal hearing and 19 with hearing loss) matched for age, sex and educational background. All participants were also assessed for hearing, anxiety and depression, and participants with tinnitus were also assessed for tinnitus handicap. No associations were found between presence of tinnitus and cognitive performance (mean total rate correct score on the visual office-like task being 2.9 for the tinnitus group, 2.8 for the control group, p = 0.612) and perceived exertion (mean ratings of perceived exertion on the Borg CR10-scale being 5.8 for the tinnitus group, 6.5 for the control group, p = 0.063) on the visual office-like task when corrected for standard (0.125 to 8 kHz) and extended high frequency (10 to 16 kHz) hearing thresholds, anxiety, and depression. The correction for extended high frequency average (10, 12.5, 14, and 16 kHz) hearing threshold was significant for performance (p = 0.009) but not perceived exertion on the visual office-like task. Overall, the results showed extended high frequency hearing, but not tinnitus, was associated with every-day cognitive performance. This indicates clinical testing of hearing thresholds above 8 kHz could support clinicians’ identification and management of cognitive difficulties. One management method suggested by the current findings would include provision of auditory stimulation at frequencies exceeding the frequency response of many current hearing aids.

Abstract
BACKGROUND Listening effort is primarily reflective of real-world performance. Therefore, it is crucial to evaluate the listening effort to predict the performance of hearing aid (HA) users in their daily lives. PURPOSE This study aimed to investigate the relationship between listening effort, daily HA use time, and HA satisfaction. RESEARCH DESIGN This is a cross-sectional study. STUDY SAMPLE Thirty-three bilateral behind-the-ear HA users (17 females and 16 males) between 19 and 37 years were participated. All participants had bilateral, symmetric, moderate sensorineural hearing loss and at least 6 months of experience using HAs. The pure-tone average thresholds (PTA) of the participants' left and right ears were 55.34 ± 4.38 and 54.85 ± 5.05, respectively. DATA COLLECTION AND ANALYSIS First, daily HA use times of the last 30 days were derived from data logging. Second, participants were asked to fill in the Satisfaction with Amplification in Daily Life Scale questionnaire (SADL). Lastly, participants performed the dual-task paradigm to evaluate listening effort. The dual-task paradigm consisted of a primary speech recognition task that included three different individualized signal-to-noise ratio (SNR) conditions, that is, SNR100, SNR80, and SNR50, which the participant could understand 100, 80, and 50% of the speech, respectively. The secondary task was a visual reaction time task that required participants to press the key in response to a visual probe (an image of a white or red rectangle). Multiple linear regression analyses were used to model the effect of factors (daily HA use time and HA satisfaction) on reaction times (RT) of each three individualized SNR sessions. RESULTS Mean daily HA use time of the participants was 5.72 ± 4.14 hours. Mean RTs of SNR50, SNR80, and SNR100 conditions were 1,050.61 ± 286.49, 893.33 ± 274.79, and 815.45 ± 233.22 ms, respectively. Multiple linear regression analyses showed that daily HA use time and HA satisfaction are significantly related to listening effort in all SNR conditions. For SNR80 condition; F (2,30) = 47.699, p < 0.001, with an adjusted R 2 of 0.745. CONCLUSION As far as we know, this study is the first to demonstrate a strong link between listening effort, daily HA use time, and HA satisfaction. Evaluating listening effort following the HA fitting session may provide preliminary information about the treatment success of HA.

Abstract
The outcome of cochlear implantation is typically assessed by speech recognition tests in quiet and in noise. Many cochlear implant recipients reveal satisfactory speech recognition especially in quiet situations. However, since cochlear implants provide only limited spectro-temporal cues the effort associated with understanding speech might be increased. In this respect, measures of listening effort could give important extra information regarding the outcome of cochlear implantation. In order to shed light on this topic and to gain knowledge for clinical applications we compared speech recognition and listening effort in cochlear implants (CI) recipients and age-matched normal-hearing listeners while considering potential influential factors, such as cognitive abilities. Importantly, we estimated speech recognition functions for both listener groups and compared listening effort at similar performance level. Therefore, a subjective listening effort test (adaptive scaling, “ACALES”) as well as an objective test (dual-task paradigm) were applied and compared. Regarding speech recognition CI users needed about 4 dB better signal-to-noise ratio to reach the same performance level of 50% as NH listeners and even 5 dB better SNR to reach 80% speech recognition revealing shallower psychometric functions in the CI listeners. However, when targeting a fixed speech intelligibility of 50 and 80%, respectively, CI users and normal hearing listeners did not differ significantly in terms of listening effort. This applied for both the subjective and the objective estimation. Outcome for subjective and objective listening effort was not correlated with each other nor with age or cognitive abilities of the listeners. This study did not give evidence that CI users and NH listeners differ in terms of listening effort – at least when the same performance level is considered. In contrast, both listener groups showed large inter-individual differences in effort determined with the subjective scaling and the objective dual-task. Potential clinical implications of how to assess listening effort as an outcome measure for hearing rehabilitation are discussed.

Abstract
Listeners vary in their ability to understand speech in adverse conditions. Differences in both cognitive and linguistic capacities play a role, but increasing evidence suggests that such factors may contribute differentially depending on the listening challenge. Here, we used multilevel modeling to evaluate contributions of individual differences in age, hearing thresholds, vocabulary, selective attention, working memory capacity, personality traits, and noise sensitivity to variability in measures of comprehension and listening effort in two listening conditions. A total of 35 participants completed a battery of cognitive and linguistic tests as well as a spoken story comprehension task using (1) native-accented English speech masked by speech-shaped noise and (2) nonnative accented English speech without masking. Masker levels were adjusted individually to ensure each participant would show (close to) equivalent word recognition performance across the two conditions. Dependent measures included comprehension tests results, self-rated effort, and electrodermal, cardiovascular, and facial electromyographic measures associated with listening effort. Results showed varied patterns of responsivity across different dependent measures as well as across listening conditions. In particular, results suggested that working memory capacity may play a greater role in the comprehension of nonnative accented speech than noise-masked speech, while hearing acuity and personality may have a stronger influence on physiological responses affected by demands of understanding speech in noise. Furthermore, electrodermal measures may be more strongly affected by affective response to noise-related interference while cardiovascular responses may be more strongly affected by demands on working memory and lexical access.

Abstract
Purpose To measure the effect of testing conditions (in the soundproof booth vs. quiet room), test order, and number of test sessions on spectral and temporal processing in normal-hearing (NH) listeners. Method Thirty-two adult NH listeners participated in the three experiments. For all three experiments, the stimuli were presented to the left ear at the subjects' most comfortable level through headphones. All tests were administered in an adaptive three-alternative forced-choice paradigm. Experiment 1 was designed to compare the effect of soundproof booth and quiet room test conditions on amplitude modulation detection threshold and modulation frequency discrimination threshold with each of the five modulation frequencies. Experiment 2 was designed to compare the effect of two test orders on the frequency discrimination thresholds under the quiet room test conditions. The thresholds were first measured in the ascending and descending order of four pure tones, and then with counterbalanced order. For Experiment 3, the amplitude discrimination threshold under the quiet room testing condition was assessed 3 times to determine the effect of the number of test sessions. Then the thresholds were compared over the sessions. Results Results showed no significant effect of test environment. The test order is an important variable for frequency discrimination, particularly between piano tunes and pure tones. Results also show no significant difference across test sessions. Conclusions These results suggest that a controlled test environment may not be required in spectral and temporal assessment for NH listeners. Under the quiet test environment, a single outcome measure is sufficient, but test orders should be counterbalanced.

Abstract
AIM The present study investigates the effect of signal degradation on perceived listening effort in children with hearing loss listening in a simulated class-room context. It also examines the associations between perceived listening effort, passage comprehension performance and executive functioning. METHODS Twenty-four children (aged 06:03-13:00 years) with hearing impairment using cochlear implant (CI) and/or hearing aids (HA) participated. The children made ratings of perceived listening effort after completing an auditory passage comprehension task. All children performed the task in four different listening conditions: listening to a typical (i.e. normal) voice in quiet, to a dysphonic voice in quiet, to a typical voice in background noise and to a dysphonic voice in background noise. In addition, the children completed a task assessing executive function. RESULTS Both voice quality and background noise increased perceived listening effort in children with CI/HA, but no interaction with executive function was seen. CONCLUSION Since increased listening effort seems to be a consequence of increased cognitive resource spending, it is likely that less resources will be available for these children not only to comprehend but also to learn in challenging listening environments such as classrooms.

Abstract
Objective: Pure tone audiometry may seem to be a relatively easy task for the participant but it may involve cognitive as well as sensory abilities. The aim of this study is to examine the relationship between hearing thresholds in the frequency range 0.125-8 kHz and the core executive function cognitive flexibility in healthy individuals with normal hearing.Design: Experimental study measuring correlations between different pure-tone hearing threshold measures and cognitive flexibility. Pure tone air conduction audiometry (frequencies 0.125-8.0 kHz) and two tests of cognitive flexibility (information updating and shifting ability) were conducted.Study sample: Seventy-two subjects (aged between 21 and 36) with normal hearing (<20 dB HL) for the tested frequencies.Results: Four measures of average pure tone hearing thresholds were negatively correlated with cognitive flexibility.Conclusions: Pure-tone air conduction hearing thresholds seem to be related to cognitive flexibility in healthy individuals with normal hearing.

Abstract
Listening effort is increasingly recognized as a factor in communication, particularly for and with nonnative speakers, for the elderly, for individuals with hearing impairment and/or for those working in noise. However, as highlighted by McGarrigle et al., International Journal of Audiology, 2014, 53, 433-445, the term "listening effort" encompasses a wide variety of concepts, including the engagement and control of multiple possibly distinct neural systems for information processing, and the affective response to the expenditure of those resources in a given context. Thus, experimental or clinical methods intended to objectively quantify listening effort may ultimately reflect a complex interaction between the operations of one or more of those information processing systems, and/or the affective and motivational response to the demand on those systems. Here we examine theoretical, behavioral, and psychophysiological factors related to resolving the question of what we are measuring, and why, when we measure "listening effort." This article is categorized under: Linguistics > Language in Mind and Brain Psychology > Theory and Methods Psychology > Attention Psychology > Emotion and Motivation.

Abstract
RESUMO Objetivo Mensurar o esforço auditivo com o uso de um paradigma de tarefa dupla de memória operacional e analisar a significância clínica do desempenho de indivíduos normo-ouvintes. Método Participaram 10 adultos jovens, entre 18 e 30 anos, de ambos os gêneros, normo-ouvintes classificados segundo a média quadritonal (500, 1000, 2000 e 4000Hz) e com nível sociocultural similar. Os participantes foram submetidos à anamnese audiológica, meatoscopia e audiometria tonal limiar. Para a mensuração do esforço auditivo, utilizou-se um paradigma de tarefa dupla, composto por tarefas de percepção de fala e memória operacional de logatomas, palavras reais e sentenças sem sentido. Anteriormente à mensuração, o paradigma de tarefa dupla foi realizado no silêncio com o intuito de treinar os participantes a desempenharem as tarefas adequadamente. Após a fase de treinamento, este paradigma foi realizado em duas situações de escuta distintas, nas relações sinal/ruído de +5 e -5dB, com o ruído do tipo White Noise. Resultados A comparação do desempenho por orelha, direita ou esquerda, nas duas relações sinal-ruído demonstrou efeito significante para as tarefas de percepção de fala de logatomas e sentenças sem sentido em ambas as orelhas, porém para a tarefa de esforço auditivo e memória operacional houve diferença significante apenas para a orelha direita. Conclusão Foi possível mensurar o esforço auditivo com o uso do paradigma proposto e este instrumento demonstrou ser sensível para a quantificação deste parâmetro auditivo.

Abstract
OBJECTIVE To examine the relationship between extended high-frequency pure tone hearing thresholds (frequencies 10 to 14 kHz) and working memory capacity (WMC), inhibitory control, and cognitive flexibility. DESIGN Experimental study measuring correlations between different high-frequency hearing threshold measures and cognitive measures. STUDY Pure tone audiometry was assessed in the extended high-frequency (frequencies 10, 12.5 and 14 kHz). Subjects were also tested regarding WMC, inhibitory control (response inhibition), and cognitive flexibility (information updating and shifting ability). SAMPLE Forty-three subjects between 20 and 29 years old with normal hearing (≤ 20 dB HL) in the frequency range between 0.125 to 8 kHz. RESULTS No significant correlations were seen between high-frequency hearing thresholds defined as average best and worst ear high-frequency hearing thresholds and the cognitive measures. Differences between the best and the worst ear showed significant negative correlations with inhibitory control and global executive function (combination score for WMC, inhibitory control and cognitive flexibility). CONCLUSIONS The present study suggests that global executive functions, more specifically response inhibition, and hearing threshold asymmetry in the extended high-frequency range are interrelated.
