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 shows that IHC dysfunction impairs temporal-envelope coding in auditory-nerve fibers without altering peripheral tuning, contributing to hidden hearing loss.

This study differentiates the physiological signatures of cochlear synaptopathy and inner hair cell damage using non-invasive assays in chinchilla models.

The paper investigates how reduced spectral resolution affects temporal-coherence-based source segregation and speech intelligibility in hearing-impaired listeners using cochlear implants.

This paper estimates cochlear frequency selectivity using a convolution model of forward-masked compound action potentials in chinchillas, showing close agreement with auditory nerve tuning curves.

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

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

The paper shows that acoustic trauma enhances noise envelopes more than speech envelopes, impairing speech understanding in noise.

This study shows that distorted tonotopy, not reduced temporal precision or broader tuning, severely impairs neural representation of natural speech in noise after acoustic trauma.

The paper shows that adding across-channel temporal-coherence processing improves predictions of consonant confusions in speech categorization, suggesting its role in speech understanding in noise.

The paper investigates how temporal fine structure (TFS) affects consonant identification in multi-talker babble, finding that TFS conveys voicing information beyond what envelopes convey.

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.
