This study aimed to: (a) examine the relationship between auditory demand and listening effort, affect, and fatigue, focusing on the moderating role of hearing loss; and (b) assess whether listening effort and affect mediate the effect of auditory demand on fatigue. A total of 130 participants, with and without hearing loss, participated in EMA over 5.5 days, answering questions on listening effort, fatigue, and listening environment attributes. Auditory demand was defined by contextual and subjective components derived from EMA responses. LME models analyzed the effect of auditory demand on listening effort, affect, fatigue and the moderating role of hearing loss. Additional models tested mediation by listening effort and affect. Results: highlighted that both contextual and subjective auditory demand significantly increased listening effort with stronger effects in those with more hearing loss. No effects of contextual auditory demand on affective state were observed, nor was there a moderation effect of hearing loss. An effect of subjective auditory demand on affect was observed, but no moderation of hearing loss was present. Contextual and subjective auditory demand predicted fatigue (β = 0.07-0.14, p < .01-p < .001) with amplified effects present in those with more hearing loss (pinteraction < .01) for contextual demand. Mediation analyses highlighted that listening effort contributed to the demand-fatigue relationship, though patterns differed by demand type. The results indicate that increased listening effort, rather than negative affect, may underlie the association between auditory demand and fatigue.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165251413329"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12966542/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147345382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neurons of the mammalian lateral superior olive (LSO) are sensitive to ILDs and envelope-ITDs of acoustic stimuli. Bushy cells in the anteroventral cochlear nucleus convey relevant information from auditory nerve (AN) fibers to the LSO. More specifically, spherical bushy cells (SBCs) send ipsilateral excitatory inputs, while globular bushy cells (GBCs) project to the contralateral medial nucleus of the trapezoid body that provides inhibitory inputs to the LSO. Previous studies in vivo reported an enhancement of phase-locking in bushy cells compared to AN. This enhancement has been hypothesized to benefit temporal coding in binaural neurons, but its actual contribution in LSO remains unclear. Here we investigate this question by computational modeling of binaural circuity incorporating the AN, SBC/GBC, and LSO stages. Both bushy cell models were calibrated to replicate known physiological responses, including the representative peristimulus time histograms for high-frequency tones and enhanced phase-locking to low-frequency envelopes. We then simulated the binaural tuning of LSO with and without the bushy cell stage. The synaptic inputs to the LSO model were adjusted so that the simulated ILD-tuning remains unaltered between the input configurations. By adding the bushy cell stage, the simulated binaural response of LSO became more sharply tuned for envelope-ITDs. Furthermore, the envelope-ITD sensitivity was extended up to around 600 Hz, matching previously observed physiological limits. These results provide computational evidence for the functional benefit of having bushy cells in the binaural sound localization circuit.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261421708"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12901860/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146167661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This bias in emotional response may negatively impact well-being, leading to decreased social participation and increased loneliness. The present study examined whether the Positive Focus intervention-encouraging hearing aid users to focus on positive listening experiences-could influence emotional response to environmental sounds. Thirty participants were randomly assigned to either a Positive Focus or a Control group. At the initial laboratory visit, all participants were fitted with study hearing aids and performed affective ratings of 120 environmental sounds. Over 3 weeks, both groups wore the hearing aids; the Positive Focus group additionally reported daily positive listening experiences via a text message. At the end of the three-week period, participants completed questionnaires on hearing aid outcomes and repeated the affective ratings. The Positive Focus intervention did not alter emotional responses to environmental sounds in a laboratory setting. However, regression analyses revealed that valence ratings of typically pleasant sounds moderated the effectiveness of Positive Focus on hearing aid benefit; the intervention was more effective for individuals less naturally inclined to respond positively to such sounds. These findings suggest that valence screening may help identify individuals most likely to benefit from Positive Focus, supporting more personalized hearing care strategies.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261437852"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13080153/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147677896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One thousand five hundred and seven hearing aid users (mean age = 60 years) completed an online survey about their music listening behavior and use of hearing aids. Results showed that whilst hearing aids support engagement in music listening, they also present many issues and overall helpfulness is mixed. The most commonly reported issue was distortion and poor sound quality, particularly in loud or live contexts. The most frequently reported strategy for reducing distortion was to remove hearing aids altogether. Only a third of the sample reported using a music program and effectiveness was mixed, suggesting that manufacturer music programs do not currently provide significant benefits for music listening, and further research into the use, uptake and efficacy of music programs is needed. We call for further research into signal processing strategies for music especially for high sound levels such as live music or concert settings. The positive impact of mindsets supporting proactive behaviors, perseverance, adaptation, and experimentation with different technologies, genres, and listening environments was highlighted, strengthening the evidence base for audiologists to provide music listening guidance in the clinic.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165251396517"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12833179/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146020269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study measured STM detection thresholds in young normal-hearing and older hearing-impaired listeners and evaluated whether the revised Computational Auditory Signal Processing and Perception model (CASP) can account for individual performance. Thresholds were obtained for six modulation detection conditions, defined by combinations of spectral (0, 1, and 2 c/o) and temporal (4 and 12 Hz) rates. To individualize CASP, outer and inner hair cell loss estimates were obtained from audiometric and Adaptive Categorical Loudness Scaling (ACALOS) data. The results showed systematically elevated thresholds in older hearing-impaired listeners as compared to the young normal-hearing group, particularly at higher spectral rates. The model simulations reproduced overall threshold patterns, but substantially underestimated group differences and interindividual variability in the data. Moreover, the simulations showed limited sensitivity to estimates of outer and inner hair cell loss, supporting the idea that additional supra-threshold mechanisms contribute to STM deficits. While these findings demonstrate the potential of auditory models to predict STM performance, they also highlight the need for refined representations of peripheral and central processing to account for individual STM detection thresholds.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261425853"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12925006/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146229222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Speech-in-noise perception was assessed with a matrix test. Reaction times showed strong within-participant consistency across implementations, demonstrating robustness over time and across different delivery and response setups. Individual differences in sensitivity to spectral and temporal modulations were evident and showed strong correspondence between the two implementations. Reaction-time-based modulation transfer functions matched those reported in previous psychophysical studies. Notably, reaction times correlated most strongly (r = 0.6-0.7) with speech-in-noise scores for spectrotemporal modulations relevant to speech, particularly spectral densities of 0.25-0.5 cycles/octave combined with temporal rates up to 16 Hz.

The magnitude of these effects depends on the level difference between the direct and processed sound and on the processing delay. A critical issue for HA uptake and use is own-voice perception, which the current study focused on. Its aims were to investigate (1) whether short processing delay is preferred over longer delays, (2) how processing delay influences different perceptual dimensions related to own-voice perception, and (3) whether spectral discrimination abilities can predict delay preference. Twenty-four individuals with mild-to-moderate hearing impairment participated. Using prototype receiver-in-the-canal HAs, processing delays of 0.5, 5, and 10 ms were compared. Delay preference was assessed using a paired-comparison task. Perceptual dimensions relating to own-voice perception were investigated using a customized version of the \"Own Voice Qualities\" questionnaire. Spectral discrimination abilities were assessed using a spectral ripple discrimination (SRD) task. The analyses showed that the 0.5-ms delay was preferred over the longer delays. Furthermore, the 0.5-ms delay received better ratings related to tonality perception (e.g., attributes such as metallic and sharp) and own-voice quality compared to the 10-ms delay. SRD abilities did not predict delay preference. Overall, these results provide insights into how open-fit HAs can be optimized with respect to own-voice perception.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261435260"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13009764/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147500133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Asymmetric pulses have been proposed to mitigate this issue; however, their practical application in CI strategies remains challenging owing to the potential temporal overlap between pulses from adjacent channels. In the present study, we employed a computational model to evaluate the effects of charge-balanced asymmetric pulses with varying second-phase durations on the spread of neural excitation (SOE) and neural activation. The SOE was assessed under different electrode-auditory nerve fiber (ANF) distances to explore the interaction between the pulse configuration and the neural interface. At greater electrode-ANF distances, increasing the second phase lowers the stimulation thresholds effect. However, at shorter distances, a prolonged second-phase duration induces neural inhibition and degraded neural activity patterns. Therefore, the efficacy of asymmetric pulses in reducing the SOE depends on the electrode position. Furthermore, a moderate increase in the second-phase duration may offer a promising direction for optimizing CI stimulation and enhancing speech perception.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261438853"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13070182/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147647011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, interaural time difference (ITD) discrimination tends to be substantially worse in CI users. However, only very few studies have investigated how CI stimulation affects the \"precedence effect\" (PE), and how this might be affected by abnormal hearing experience during development. We performed behavioral experiments to measure temporal weighting functions (TWFs) to quantify the PE in three different cohorts of rats: normally hearing (NH) acoustically stimulated, neonatally deafened (ND) CI-stimulated, and adult deafened (AD) CI-stimulated animals. Lateralization responses were recorded to bursts of eight stimulus pulses in which the ITD of each pulse varied independently, and probit analysis revealed the perceptual weight of each pulse. The NH and ND-CI cohorts were tested at 50, 300, and 900 pps; the AD-CI animals were tested only at 300 pps. The NH animals show a pronounced \"onset dominance\" at higher pulse rates, that is, the weighting of the first pulse was much larger than for subsequent pulses, exactly as one would expect given previous studies on human listeners. In contrast, the TWFs for the ND-CI and AD-CI animals were much flatter, with a reduction of onset dominance by ∼75%, especially for higher pulse rates. Since neither of our CI cohorts had any experience of reverberation in their electric hearing, we interpret these results to indicate that the PE may require domain-specific experience to develop.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261441709"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13121490/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147786412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Total auditory deprivation triggers cross-modal neural reorganization, but in patients with partial hearing deprivation, how residual auditory function is balanced with the compensatory plasticity of other sensory modalities remains unclear. Previous studies have reported conflicting findings, potentially due to differences in study populations or task designs. Here, we investigated hierarchical neural processing in a homogeneous cohort of 37 congenital SSD patients (31.6 ± 6.5 years, 18 males) and 32 normal-hearing (NH) controls (30.6 ± 7.3 years, 14 males) using both auditory and visual oddball tasks with electroencephalography (EEG). In the auditory task, SSD patients presented reduced amplitudes of early exogenous components (N1, P2) and mismatch negativity (MMN), but preserved late endogenous components (N2, P3), compared with NH controls. Conversely, in the visual task, SSD patients presented increased early visual N1 amplitudes with intact visual mismatch negativity (vMMN) and endogenous components (N2, P3). No latency differences in the above components were observed. These results reveal a difference in plasticity between lower- and higher-level processing. Our findings indicate that functional plasticity in SSD patients occurs predominantly at sensory stages and is characterized by diminished auditory and compensatory elevated visual neural activity, whereas higher-level discrimination processing in either modality is largely unaffected. These findings clarify prior discrepancies, establish a hierarchical framework for understanding neuroplasticity in partial sensory deprivation, and have implications for rehabilitation strategies for SSD patients.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165251413850"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12816557/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145999400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
