Listeners showed 13.2% higher accuracy for voice clones. Overall, listeners adapted to the noise-vocoded speech and improved by around 16% over the course of 40 sentences in the first block only, regardless of whether voices were human or cloned. The intelligibility benefit for cloned voices thus persisted for noise-vocoded speech, and listeners adapted to noise-vocoded cloned voices as much as for noise-vocoded human voices.

While auditory behaviour has been well characterised for one or a few sources, it remains unclear how listeners perceive scenes containing many simultaneous sounds. As multiple sound sources combine into a single acoustic mixture, separating individual sources becomes increasingly difficult, potentially requiring listeners to rely on summary representations rather than discrete object-based parsing. <i>Auditory numerosity judgement</i>, the ability to estimate how many distinct sound sources are present, can provide a way to probe how listeners perceive such complex acoustic scenes. Here, we measured numerosity judgements along the three dimensions of auditory space: azimuth, elevation, and distance, allowing each spatial axis to be examined in isolation. As these dimensions rely on markedly different spatial cues and differ strongly in spatial acuity, this design enabled the dissociation of spatial and non-spatial contributions to numerosity perception. Across dimensions, numerosity judgements showed no systematic relationship with individual spatial hearing performance. Speech intelligibility likewise exerted only a weak influence. In contrast, perceived numerosity was significantly modulated by the spectrotemporal coverage of the acoustic mixture, a summary statistic independent of spatial dimension or higher-lever linguistic factors. Together, these findings suggest that auditory numerosity judgement is largely insensitive to spatial hearing precision and instead reflects more general principles of how complex sound mixtures are represented at the scene level.</p>","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261474325"},"PeriodicalIF":3.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13424768/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148632313","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.</p>","PeriodicalId":48678,"journal":{"name":"Trends in Hearing","volume":"30 ","pages":"23312165261421708"},"PeriodicalIF":3.4,"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}

However, bilateral CI listeners continue to perform poorer than acoustic-hearing listeners on spatial-hearing tasks such as sound localization. One explanation is that stimulation strategies and the lack of coordination across sound processors degrade the fidelity of binaural cues. To provide further insight on this issue, this study compared the binaural cues transmitted by two CI stimulation strategies: a spectral peak-picking stimulation strategy and a constantly stimulating strategy. Two clinical CI sound processors were placed on a binaural manikin centered in a horizontal ring of loudspeakers in an anechoic chamber. Speech and non-speech stimuli were presented from the loudspeakers and the resulting electrical pulse trains were recorded. Envelope interaural time differences and interaural level differences were extracted from the recordings. Binaural cues were compared between the two stimulation strategies and against acoustic cues measured using behind-the-ear microphones. Results showed that, compared to the constantly stimulating strategy, the spectral peak-picking strategy led to more variable and less monotonic binaural cues, which could constrain sound-localization abilities. These findings highlight the need for bilateral coordination of CIs in multiple domains, including electrode selection in peak-picking stimulation strategies and pulse timing.
