However, early intervention also presents significant challenges to postoperative assessment. Parent-reported questionnaires have demonstrated notable advantages in outcome evaluation for infants and young children. In the present study, we investigate the auditory development of Mandarin-speaking children with cochlear implants (CIs) using the Chinese version of the Parents' Evaluation of Aural/Oral Performance of Children (PEACH). A total of 187 children with CIs participated. According to their age at implantation, the children were classified into five groups: <12 months, 13-18 months, 19-24 months, 25-42 months, and >42 months. Evaluations were administered at CIs switch-on (baseline), and at 1, 2, 3, 6, 12, 24, 36, 48, 60 months post switch-on, resulting in 933 records. We employed a linear mixed-effects model to identify key factors influencing PEACH performance. Results show that the PEACH scores enter a stable plateau phase after approximately 20 months of CI use. Notably, children who received CIs at a younger age exhibited faster improvements in auditory functional performances. This advantage is particularly prominent in children implanted before 18 months of age. Analysis indicated that significant influencing factors include age at implantation, duration of CI use, development quotient, and preoperative residual hearing level. This study explores the longitudinal trends of early aural/oral performance in children with CIs. The findings emphasize the critical importance of early cochlear implantation for improving outcomes while revealing the challenges associated with the late-implanted children.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261434074"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13121480/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147786380","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}

Prior research has predominantly used isolated words or sentences without context, a method that lacks ecological validity and may place greater demands on working memory (WM) due to the absence of contextual linguistic information. This study examined the semantic processing of experienced CI users (N = 21) and age-matched normal-hearing controls (NH, N = 21) using an audiobook. We measured neuroelectric brain activity while participants listened to a story in which we inserted an incongruent word every 45 s, herein, the E45 condition. WM and behavioral semantic judgment were quantified with a listening span test. Temporal response functions, linear models that characterize how continuous stimulus features are temporally mapped onto neural responses, were used to quantify speech neural tracking of audio features (envelope, word onset, word surprisal) during ongoing speech. Results showed reliable neural tracking of acoustic features and word surprisal. Compared to the Control condition, E45 elicited larger TRF-N400 responses in both groups. Although TRF-N400 amplitudes were comparable between CI and NH listeners, CI users exhibited delayed responses. In NH listeners, larger N400 effects were associated with greater semantic judgment accuracy, linking neural responses to behavioral performance. These results show the validity of an ecologically valid paradigm that does not require an explicit behavioral response to quantify semantic processing in CI users.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261439202"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13133447/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147786378","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}

Remote applications also have large potential to increase statistical power, accessibility, and diversity in research studies, but their utility and validity are still unclear. We developed and evaluated a web-based listening test system called AUDITO for cochlear implant (CI) research. By exploiting the advances in wireless streaming technology and personal mobile devices, AUDITO can be used to flexibly implement and administer a wide range of listening tests remotely or in-the-lab. The system was designed to be easy to use without programming. Technical features were implemented to ensure signal quality over wireless streaming. A pilot study with 20 experienced CI recipients was performed to evaluate the validity of remote testing across test paradigms. Comparisons of interest included the presentation of stimuli via cable versus Bluetooth streaming and testing remotely versus in-the-lab. Three listening tests were implemented to measure speech perception for sentences, digits in noise and spectro-temporal resolution. A questionnaire was administered to collect user feedback. The system worked reliably with various Bluetooth-compatible setups including desktop and laptop computers, tablets, and smartphones. Test results were consistent between listening modalities and across tested conditions, confirming the validity of web-based testing for these measures. User feedback was positive for system usability and function, while signal quality was not reported to be compromised via streaming. Web-based systems such as AUDITO can facilitate data collection, enable research collaboration and improve accessibility and inclusion in CI research.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261416179"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12929878/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147277293","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}

Termed rollover, this phenomenon is neglected during hearing aid (HA) fitting. A previous study introduced \"sweet-spot compression\" (SSC)-an amplification strategy for preventing rollover and improving listening outcomes at moderate to high levels. SSC aims to place speech in that area of an individual's performance-intensity function where both SI and listening comfort are high-the \"sweet spot.\" To achieve this, it combines high compression ratios with long time constants to provide quasi-linear amplification in the sweet-spot area. Using a HA simulator, headphone presentation, and 16 participants with rollover, SSC previously outperformed a clinical reference condition in terms of listening outcome. Here, we extended this work by (a) mapping out individual differences in the most comfortable speech level (MCL) and SI in noise at moderate to high levels, and (b) evaluating the listening outcome with SSC further. Using a wearable research HA, we tested 18 randomly chosen participants with mild to moderate hearing loss. Our analyses showed clear individual differences in MCL and SI with linear amplification. SSC gave better SI and was clearly preferred in quiet and in noise relative to a clinical reference condition. At the group level, rollover did not occur for either SSC or the reference condition. At the individual level, we found fewer cases of rollover with SSC than with the reference condition. Overall, we conclude that SSC shows promise with respect to improving listening outcomes at moderate to high levels.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261431931"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13009919/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147469820","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 young adults with normal hearing completed a sustained listening task under speech-on-speech masking while simultaneously performing a secondary memory task, tested across four acoustic processing conditions.

Subjective fatigue ratings also increased across sessions, though without systematic differences between conditions. Behavioral results showed sequence effects: performance declined in intermediate conditions, whereas it remained stable in the easiest and hardest conditions, suggesting that both fatigue and motivational regulation shaped outcomes. Together, these findings demonstrate that sLE is associated with increased subjective fatigue and fatigue-related sleepiness. They further support the PUI as a promising objective physiological marker of fatigue-related sleepiness associated with sLE, complementing subjective and behavioral assessments.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261441694"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13133488/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147786451","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 study evaluates the effect of virtual animated characters' head movements on participants' communication behavior and experience. Triadic conversations were conducted between a study participant and two confederates. To facilitate the manipulation of head movements, the conversation was conducted in telepresence using a system that transmitted audio, head movement data and video with low delay. The confederates were represented by virtual animated characters (avatars) with different levels of animation: Static heads, automated head movement animations based on speech level onsets, and animated head movements based on the transmitted head movements of the confederates. A condition was also included in which the live videos of the confederates' heads were embedded in the visual scene. Sixteen young adults (19-32 years) with self-reported normal hearing participated in the study, i.e., 16 triads were measured. The results show significant effects of animation level on the participants' speech and head movement behavior as recorded by physical sensors, as well as on the subjective experience. The largest effects were found for the range of head orientation while speaking, the head orientation while listening, and the perceived realism of avatars. We therefore conclude that the representation of conversation partners affects communication behavior, which may be considered when natural speech and movement behavior is desired.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261432065"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13065277/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147634999","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 study examined whether deviations from National Acoustic Laboratories Non-Linear (NAL-NL2) real-ear targets (real-ear-to-target difference, RTD) predicted changes in Speech, Spatial, and Qualities of Hearing Scale (SSQ) scores, and whether they related to aided speech recognition in quiet. The effects of hearing loss and patient characteristics were also considered. Data from 298 adults (mean age 65 years) fitted with new or replacement HAs (66%) were analyzed. Baseline measures included unaided speech recognition in quiet and a 17-item SSQ; follow-up measures included aided speech recognition in quiet, RTDs, and the SSQ. Principal Components Analysis summarized RTDs into overall gain (RTD1) and high-frequency gain (RTD2). The effects of treatment, RTD, pure-tone average (PTA), audiogram slope, asymmetry, age, gender, and HA experience on SSQ scores were investigated with mixed-effects models. Hearing-aid use improved both SSQ score (by 1.4 points) and speech in quiet. The RTD1 predicted neither SSQ nor speech scores. Underamplification above 2 kHz (RTD2) did not influence speech scores significantly, but reduced SSQ improvement. Higher PTA and steeper slopes were associated with lower aided speech scores, while higher PTA and age reduced SSQ improvement. Hearing-aid experience showed modest SSQ-domain effects. About half of SSQ variance reflected between-subject differences. HAs provide substantial benefit, despite moderate NAL-NL2 mismatches.

One of the factors limiting pitch sensitivity in multi-electrode as compared to single-electrode stimulation can be intracochlear interactions of electrode signals (i.e., channels). We measured temporal-pitch discrimination sensitivity for loudness-balanced dual-electrode stimuli with various spatio-temporal configurations in listeners with MED-EL implants. We hypothesized a link between pitch sensitivity and tonotopic separation as well as (monaural) temporal electrode asynchrony, the latter resulting in various combinations of inter-pulse intervals in the compound stimuli received by the auditory nerve. Per-electrode stimulus types were high-rate (i.e., 1,000-pps) pulse trains with a 100-Hz amplitude modulation and both with and without additional pulses inserted with short inter-pulse intervals at modulation peaks. The temporal asynchrony had a detrimental effect for tonotopic separations below 2.2 mm but not for separations of 7.1 mm and more. This pattern was largely consistent across stimulus types and can be attributed to spectro-temporal channel interactions. When compared with sensitivity to unmodulated 100-pps pulse trains [Lindenbeck et al., Trends in Hearing, 28, Article 23312165241271340 (2024)], stimuli without short inter-pulse interval pulses yielded lower sensitivity while stimuli with short inter-pulse interval pulses approached low-rate sensitivity for some tonotopic separations. Despite lower sensitivity overall, high-rate pitch cues seemed to be integrated (i.e., improved) more across the two electrodes than low-rate pitch cues when compared to single-electrode stimulation. These results suggest that short inter-pulse interval pulses are beneficial for temporal-pitch sensitivity in dual-electrode configurations.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165251408983"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12796140/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145960496","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}

Monaural speech intelligibility models cannot predict this spatial release from masking. A binaural front end is proposed that can be combined with monaural models to do so. From the noisy speech signals at the two ears, it produces binaurally-enhanced monaural signals that can be evaluated by monaural models. A stationary and a time-dependent version of the front end were tested here with the monaural Hearing Aid Speech Perception Index (HASPI) that compares the envelope modulations of the noisy speech to those of the clean speech. The model predictions were compared to the intelligibility scores of three datasets collected with normal-hearing listeners via headphones measurements in anechoic conditions. A stationary speech-shaped noise (SSN) was tested at 10 azimuths in dataset 1. In dataset 2, an SSN or a non-stationary noise were tested at three azimuths, with or without ideal binary mask processing. In dataset 3, the competing sounds were obtained by mixing the signals from an SSN co-located with the target speech, a diffuse noise coming from all directions, and a spatially-separated SSN. The stationary-front-end predictions are very accurate in the conditions with a spatially-separated SSN, while monaural HASPI predictions at the ear with the better signal-to-noise ratio under-estimate intelligibility. The front-end predictions are slightly less accurate for non-stationary noise but under-estimate intelligibility with diffuse noise. The time-dependent version of the front end systematically over-estimates intelligibility at low signal-to-noise ratios.","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261422005"},"PeriodicalIF":3.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13009958/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147487818","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}
