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.</p>","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261441709"},"PeriodicalIF":3.4,"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}

Twenty listeners with mild to moderately severe sensorineural hearing loss rated the sound quality on different subscales for two types of signal mixtures: speech in music (Overall Sound Quality, Speech Clarity, and Music Pleasantness) and speech in noise (Overall Sound Quality, Speech Clarity, and Noisiness) at three speech-to-background ratios (SBR: -10, 0, +10 dB). Speech in music was a 10-second-long spontaneous speech excerpt with a duration-matched classical music excerpt. Speech in noise had the same speech signal mixed with speech-shaped noise. Conventional DRC applied a 50-ms release time to the mixed signals, whereas independent DRC applied a 50-ms release time for speech and a 2000-ms release time for music or noise <i>before</i> mixing. The control conditions included linear amplification applied to the signals before and after mixing. Independent DRC resulted in higher overall sound quality, music pleasantness, and lower noisiness ratings than conventional DRC, regardless of SBR. Independent DRC resulted in higher speech clarity ratings than conventional DRC at lower SBRs. The results are generally supported by acoustic metrics, indicating more effective compression and higher output SBRs, especially at lower input SBRs, and reduced across-source modulation correlations with independent DRC. These findings extend the literature on the advantages of independent compression of sound sources by demonstrating sound quality benefits across multiple sub-scales for listeners with hearing loss across music and noise backgrounds.</p>","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261471119"},"PeriodicalIF":3.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13379648/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148473648","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}

Ninety-eight adult workers aged 18 - 75 years completed standard (0.25 - 8 kHz) and extended high-frequency (10 - 14 kHz) audiometry, Arabic diotic and antiphasic digits-in-noise (DIN) testing, and an Arabic Noise Exposure Structured Interview.

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.</p>","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165251413850"},"PeriodicalIF":3.4,"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}

Yet the degree of difficulty differs widely among individuals, often unrelated to the clinical gold standard for evaluating hearing, the pure-tone audiogram. Research has isolated both auditory and nonauditory factors responsible for these differences, but these factors do not operate in isolation. In the present work, a generic computational model involving simultaneous cue sensitivity, cue reliance, and decision noise provided an integrative framework for identifying sources of between-listener variance not accounted for by the audiogram. The framework was applied to performance differences within and between normal-hearing (NH) and hearing-impaired (HI) groups in the processing of linguistic, acoustic, and statistical cues supporting speech recognition in noise. The primary source of performance differences <i>between</i> groups was differences in sensitivity for the subtle, but largely stationary acoustic cues required for <i>speech recognition</i>. The overwhelming source of performance differences <i>within</i> groups was differences in decision noise associated with more salient, but highly variable statistical cues for <i>speech separation</i>. For speech separation, HI listeners placed far greater reliance than NH listeners on the one cue for which they were most sensitive. HI listeners, but not NH listeners, benefitted by shifting all acoustic information to this most relied on cue.

CI listeners with etiologies related to auto-immune dysfunction, such as Meniere's disease, tended to have the opposite profile, with lowest thresholds near the middle of the array.
