This study examines how working memory and inhibitory control affect speech-in-noise perception across the adult lifespan and finds that both cognitive functions predict performance on different types of speech-in-noise tasks.

This study examines how sedation affects distortion-product and stimulus-frequency otoacoustic emissions in chinchillas, finding elevated low-frequency DPOAE amplitudes and variable SFOAE changes under sedation.

This study finds reduced cortical activation and increased alpha-band functional connectivity in ASD during passive auditory spatial attention tasks compared to typically developing children.

The paper investigates how digital noise-reduction processing affects subcortical speech encoding and links these effects to behavioral outcomes.

This study examines the correlation between distortion product otoacoustic emissions and audiometric thresholds in extended high frequencies using calibrated measurements.

The paper uses individual differences across 200 participants to show that robust temporal fine-structure (TFS) sensitivity is linked to better resilience against reverberation and reduced listening effort in speech perception tasks.

This study investigates whether musical training enhances early auditory neural responses and finds no evidence of such enhancement in a large-scale, multi-site study.

The paper introduces a system-identification method to measure auditory temporal processing with high resolution, revealing how attention affects neural responses across different auditory pathway stages.

This study applies deep learning models to improve speech intelligibility for cochlear implant users in multi-talker noise, showing significant improvements over conventional methods.

This study shows that induced alpha and beta brain rhythms correlate with single-trial speech intelligibility in noisy environments.

This paper develops and validates a web-based platform for psychoacoustic experiments, showing agreement with lab-based results on multiple tasks.

The paper reports widespread cochlear neural damage in normal-hearing individuals and animals using physiological assays, despite no clinical hearing loss.

The paper evaluates behavioral and EEG-based measures as individualized assays for temporal fine structure (TFS) coding in the auditory system and finds that adjusted binaural measures show robust correlations with TFS processing.

The paper estimates cortical synchronization limits to dynamic binaural cues and links them to perceptual limitations in auditory spatial perception.

The paper investigates how neural envelope coding of speech is influenced by background sounds and acoustic features, showing that modulation masking and fine structure shape speech intelligibility across listening conditions.

This paper introduces a unifying framework for analyzing both spike-train and evoked neural responses to complex sounds using advanced spectral analyses, improving the understanding of perceptual deficits in hearing loss.

The paper examines extraneous factors affecting non-invasive assays for cochlear synaptopathy and shows correlations among physiological measures indicative of synaptopathy.

The paper examines how beta and gamma frequency bands mediate different aspects of cortical resting-state network maturation from age 7 to 29.
