This paper develops a machine-learning classifier using dynamic amplitude-modulated EFRs to detect cochlear neural degeneration in animals and humans, showing it can distinguish age groups without retraining.

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 shows that central auditory decline occurs before cochlear deficits in a D-galactose-induced aging model in rats.

The paper shows that reduced neural encoding of temporal fine structure in middle age predicts increased listening effort in noisy environments despite normal hearing.

This paper measures neural synchronization to different sound timescales in human listeners to determine how distraction affects auditory processing.

This study shows that middle-aged adults have less distinct neural representations of speech sounds compared to younger adults, even with normal hearing, suggesting age-related cortical dedifferentiation contributes to speech perception decline.

The paper combines sensory coding and listening effort measures to predict speech intelligibility in noise.

This paper introduces a faster and more efficient method to measure envelope following responses (EFRs) using dynamic amplitude-modulated stimuli, achieving higher spectrotemporal resolution and reduced recording time across multiple species.

This study shows that acoustic trauma leads to non-homeostatic gain changes in auditory cortex neurons, contributing to hypersensitivity to sound.

The paper identifies neural signatures of poor multi-talker speech perception in adults with normal hearing, linking it to phase locking to frequency modulation cues and cognitive listening effort.

This study investigates how aging affects the sensitivity to temporal envelopes of speech-like sounds in rats, finding increased sensitivity to onset and periodicity in the inferior colliculus.
