Mutual Information Analysis of Neural Representations of Speech in Noise in the Aging Midbrain

This paper uses mutual information analysis to study age-related neural deficits in speech perception, finding greater informational loss in older adults, especially with meaningful speech maskers.

Weak neural signatures of spatial selective auditory attention in hearing-impaired listeners

This study investigates whether hearing-impaired listeners show weaker alpha lateralization in EEG during spatial attention tasks compared to normal-hearing listeners.

Afferent-efferent connectivity between auditory brainstem and cortex accounts for poorer speech-in-noise comprehension in older adults

The paper shows that reduced afferent connectivity between auditory brainstem and cortex in older adults predicts poorer speech-in-noise comprehension.

Using background noise to improve sound localization following simulated hearing loss

This study finds that background noise improves sound localization after simulated unilateral hearing loss, contrasting with its disruptive effects under normal hearing.

Evidence for enhanced neural tracking of the speech envelope underlying age-related speech-in-noise difficulties

The paper investigates neural envelope tracking in hearing impaired and normal-hearing adults to understand speech-in-noise difficulties and finds enhanced tracking in hearing impaired individuals.

Cingulate Cortex Atrophy is Associated with Hearing Loss in Presbycusis with Cochlear Amplifier Dysfunction

This study links cochlear amplifier dysfunction in presbycusis to brain atrophy in the cingulate cortex and cognitive decline in multiple domains.

Contributions of Low- and High-Frequency Sensorineural Hearing Deficits to Speech Intelligibility in Noise

This study investigates how low- and high-frequency hearing deficits affect speech recognition in noise, finding that low-pass speech information strongly correlates with broadband performance and that high-pass speech encoding is noise-type invariant.

Neural envelope tracking as a measure of speech understanding in cochlear implant users

This study shows that neural envelope tracking correlates with speech understanding in cochlear implant users, suggesting it as an objective measure for CI fitting and closed-loop systems.

Effect of chronic stimulation and stimulus level on temporal processing by cochlear implant listeners

This study examines how temporal processing in cochlear implant users changes over time and with stimulus level, finding improvements in discrimination and upper temporal pitch limits.

The effect of presentation level on spectrotemporal modulation detection

This study shows that higher presentation levels worsen spectrotemporal modulation discrimination thresholds in normal-hearing adults, suggesting cochlear filter broadening and neural saturation.

Neural tracking of the speech envelope in cochlear implant users

This study develops a method to measure neural speech envelope tracking in cochlear implant users by eliminating stimulus artifacts from EEG recordings.

Effect of stimulus polarity on detection thresholds in cochlear implant users: relationships with average threshold, gap detection, and rate discrimination.

The paper investigates the effect of stimulus polarity on detection thresholds in cochlear implant users, finding a correlation between polarity effects and neural survival indicators.

Speech intelligibility predicted from neural entrainment of the speech envelope

The paper demonstrates an electrophysiological measure of speech intelligibility by correlating decoded speech envelope from EEG with behavioral speech intelligibility scores.

Representation of speech in noise in the aging midbrain and cortex: aging may dominate over hearing-loss

The paper examines how aging affects speech-in-noise processing in the midbrain and cortex, finding that age-related deficits may outweigh those from hearing loss.
