The auditory frequency-following response (FFR) is a non-invasive index of the fidelity of
sound encoding in the brain, and is used to study the integrity, plasticity, and behavioral …

Aging listeners often experience difficulties in perceiving temporally complex acoustic cues
in noisy environments. These difficulties likely have neurophysiological contributors from …

Aging listeners, even in the absence of overt hearing loss measured as changes in hearing
thresholds, often experience impairments processing temporally complex sounds such as …

Listeners with normal audiometric thresholds can still have suprathreshold deficits, for
example, in the ability to discriminate sounds in complex acoustic scenes. One likely source …

Brainstem frequency-following responses (FFRs) probe the neural transcription of
speech/music, auditory disorders, and plasticity in subcortical auditory function. Despite …

Healthy aging is accompanied by listening difficulties, including decreased speech
comprehension, that stem from an ill-understood combination of sensory and cognitive …

Speech comprehension difficulties are ubiquitous to aging and hearing loss, particularly in
noisy environments. Older adults' poorer speech-in-noise (SIN) comprehension has been …

The older listener's ability to understand speech in challenging environments may be
affected by impaired temporal processing. This review summarizes objective evidence of …

Abstract Speech-in-noise (SIN) comprehension deficits in older adults have been linked to
changes in both subcortical and cortical auditory evoked responses. However, older adults' …

Hearing impairment in older people is thought to arise from impaired temporal processing in
auditory circuits. We used a systems-level (scalp recordings) and a microcircuit-level …
