However, auditory deprivation has been proposed to influence implicit learning, including in the visual modality, although evidence in adults with post-lingual deafness is limited. Therefore, we investigated implicit visual learning and its associations with speech recognition in adults with post-lingual deafness who use cochlear implants (CIs). Thus, this study focuses on the effects of late auditory deprivation rather than on the effects of early deprivation associated with congenital deafness. Adult CI users (n = 30) and a group of individuals with normal hearing (NH, n = 36) completed two implicit visual learning tasks (statistical and perceptual), a battery of challenging speech recognition tests and cognitive measures (vocabulary, working memory, attention, and verbal processing speed). NH listeners demonstrated significant visual statistical learning, whereas CI users showed a similar but nonsignificant pattern. In the visual perceptual learning task, both groups exhibited comparable learning effects. In CI users, visual statistical learning contributed to the recognition of speech in noise (words and sentences). Visual perceptual learning only contributed to the recognition of words in noise. The current findings are inconsistent with the idea that auditory deprivation beyond the sensitive period interferes with visual learning. Rather, in CI users, visual implicit learning contributes to the recognition of challenging speech. Therefore, future work might investigate whether visual learning in CI candidates is predictive of postimplantation milestones.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261434604"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13010005/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147500104","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}

Nonetheless, when spatial hearing in aging is discussed, most of the focus concerns elderly individuals with hearing impairments or presbycusis, rather than those with clinically normal hearing. In fact, auditory aging (even without presbycusis) may still result in a decline in spatial sensitivity, potentially contributing to the deterioration of key binaural functions crucial for speech understanding, such as binaural summation, squelch effect, and head shadow effect. The current study aims to determine whether Event-Related Potentials (ERPs) can reflect auditory spatial aging in populations without abnormal audiometric thresholds. Using a spatial oddball paradigm, we aim to explore the neural components associated with spatial sensitivity and examine whether these components correlate with changes in binaural integration with age. Our findings suggested a decrease in spatial auditory performance, speech in noise comprehension, and cognitive status across age even when audiometric thresholds were normal. Electroencephalograhy investigation revealed a strong correlation between N100 amplitudes and age, in addition to correlation between unmasking function and N100 amplitudes. These findings underscore the validity of ERP components as markers of spatial hearing performance and aging. This could orient the decision-making concerning the necessity for hearing rehabilitation in some cases to compensate for deficits and prevent auditory aging consequences on peripheral and central auditory processing.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165251410295"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12932879/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147285766","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 latter condition was tested binaurally and monaurally (using the only better ear (BE)). Listeners showed larger variance in SRTs than in spatial, binaural, and BE benefits, regardless of their hearing loss. A model consisting of a blind equalization-cancellation (EC) front-end and the non-blind speech intelligibility index (SII, ANSI S3.5-1997) was used to predict the measured SRTs. This model used a pure-tone audiogram to simulate hearing loss. We evaluated whether an individual suprathreshold component improves the model's prediction accuracy. This component was implemented in two ways: as an individual reference SII value (from the SRT of the S0N0 situation) and as an individually increased external noise. Both methods improved prediction accuracy for the S0N90 conditions but had no effect on spatial or binaural release from masking, nor on BE listening. No evidence was found that other available parameters would improve the prediction accuracy.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261418655"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12901929/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146183031","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}

However, the benefits of providing amplification in this population remain unclear. This study investigated the effects of amplification on hearing thresholds, speech intelligibility in quiet, and experienced listening effort in normal-hearing listeners. Forty-four young adults with clinically normal hearing participated in two experiments comparing three conditions: open ear, aided with 0 dB insertion gain to approximate acoustic transparency, and aided with 15 dB flat insertion gain. Amplification was provided using a research hearing aid fitted with closed foam earplugs. Speech intelligibility was assessed with the Oldenburg Sentence Test, and experienced listening effort was measured using Adaptive CAtegorical Listening Effort Scaling (ACALES). Listening through the nominally transparent device introduced consistent disadvantages, including elevated hearing thresholds, reduced speech intelligibility, and increased listening effort. Providing 15 dB of amplification partially compensated hearing threshold elevation, fully restored speech intelligibility and reduced experienced listening effort beyond the unaided condition. Benefits of amplification at low input levels were primarily limited by the equivalent input noise of the hearing-aid microphones. These findings suggest that amplification can provide meaningful benefits for normal-hearing listeners at low speech levels, particularly when listening effort is considered alongside speech intelligibility. Future studies should examine these effects under more ecologically valid listening conditions, and potential benefits of increased amplification in hearing-impaired listeners.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261442996"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13111850/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147730309","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}

Traditionally, age-related HL was primarily related to damage of hair cells (i.e., the sensory component of HL) however, growing evidence suggests that the endocochlear potential (i.e., the metabolic component of HL) may also play a role. In this study, we investigated the relationship between the sensory and metabolic components of HL and cognitive dysfunction in 100 older adults. Forty participants were patients with mild cognitive impairment recruited during visits to the Memory Clinic at the Danish Dementia Research Centre, while 60 participants were recruited from the general public. All participants were assessed with pure-tone audiometry and a comprehensive cognitive test battery including but not limited to tests examining, episodic memory, processing speed, and executive functions. The sensory and metabolic components of the HL were estimated based on the age-related HL components model. Metabolic HL was strongly correlated with performance on tests of processing speed, moderately correlated with performances on tests of executive function, but not significantly correlated with episodic memory performance. On the other hand, sensory HL was not significantly correlated with any of the cognitive tests. When correcting for age, the correlation between metabolic HL and processing speed remained significant. Thus, participants with lower processing speed were significantly more likely to have a larger metabolic HL. These data could lend support to the idea that shared vascular pathophysiological mechanisms are a key link between age-related HL and cognitive decline.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261447076"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13153505/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147786361","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 hearing test computes test results from age, self-reported hearing abilities, and self-assessed pure-tone thresholds.

The test was devised based on development data, collected prospectively in an online experiment from a purposive convenience sample of 251 adult American, Australian, Canadian, and Swiss participants, 58% of whom had hearing loss. Later, we externally validated the hearing test. Validation data were collected prospectively from a representative sample of 156 adult Belgian participants, 15% of whom had hearing loss. Participants completed the hearing test and audiometric assessments at home. The results for the primary screening outcome showed that the hearing test screened for mild hearing losses with a sensitivity of 0.83 [95%-confidence interval (CI): 0.65, 0.96], specificity of 0.94 [CI: 0.89, 0.98], positive predictive value of 0.70 [CI: 0.57, 0.87], and negative predictive value of 0.97 [CI: 0.94, 0.99]. Results for the secondary audiogram estimation outcome showed mean differences between estimated and gold standard hearing thresholds ranging from 2.1 to 12.4 dB, with an average standard deviation of the differences of 14.8 dB. In conclusion, the hearing test performed comparably to state-of-the-art hearing screeners.

To investigate such adverse side effects, hearing aids may be set to a 'transparent mode', aiming to replicate natural hearing through the open ear as best as possible. Such transparent hearing aids have previously been demonstrated to exhibit a small but significant disadvantage in speech intelligibility, with less conclusive effects on self-rated listening effort. Here we aimed to reproduce these findings and expand them with neurophysiological measures of invested listening effort, including parietal alpha power and pupil size. Invested listening effort was measured across five task difficulties, ranging from nearly impossible to easy, with normal-hearing participants in both aided and unaided conditions. Results well reproduced a hearing aid disadvantage for speech intelligibility and subjective listening effort ratings. As to be expected, pupil size and parietal alpha power followed an inverted u-shape, peaking at moderate task difficulties (around SRT50). However, the transparent hearing aid increased pupil size and parietal alpha power at medium task demand (between SRT20 and SRT80). These neurophysiological effects were larger than those observed in speech intelligibility and subjective listening effort, respectively. The results gain plausibility by yielding a substantial association of individual pupil size and individual parietal alpha power. In sum, our findings suggest that key neurophysiological measures of invested listening effort are sensitive to the individual additional burden on speech intelligibility that hearing aid processing can introduce.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"29 ","pages":"23312165251333225"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11970058/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143781706","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}

Forty-nine different realistic and synthetic noises were analyzed and classified according to how much they fluctuated in level over time and how much their spectra differed from the speech spectrum. Six representative noises were chosen that covered the observed range of level fluctuations and spectral differences but could still mask speech. For the six noises, speech reception thresholds (SRTs) were measured for natural and tone-vocoded words delayed 50 (early condition) and 800 ms (late condition) from the noise onset. Adaptation was calculated as the SRT improvement in the late relative to the early condition. Twenty-two adults with normal hearing participated in the experiments. For natural words, adaptation was small overall (mean = 0.5 dB) and similar across the six noises. For vocoded words, significant adaptation occurred for all six noises (mean = 1.3 dB) and was not statistically different across noises. For the tested noises, the amount of adaptation was independent of the spectrum and level fluctuations of the noise. The results suggest that adaptation in speech recognition can occur in realistic noisy environments.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"29 ","pages":"23312165251343457"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12081978/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144081428","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}

Stimulation parameters (n = 14,072 MAPs), electrophysiological auditory nerve thresholds (n = 23,215), and slopes of amplitude growth functions (n = 17,849) were obtained from 664 bilaterally implanted children (n = 1,291 devices) followed between September 2003 and July 2022.
