peripheral damage. However, it has been increasingly acknowledged that hearing loss is …

Objective evidence of temporal processing deficits in older adults

S Anderson, H Karawani - Hearing research, 2020 - Elsevier
The older listener's ability to understand speech in challenging environments may be

Synaptopathy in the aging cochlea: Characterizing early-neural deficits in auditory temporal envelope processing

A Parthasarathy, SG Kujawa - Journal of Neuroscience, 2018 - Soc Neuroscience
Aging listeners, even in the absence of overt hearing loss measured as changes in hearing

Age-related changes in neural coding of envelope cues: peripheral declines and central compensation

A Parthasarathy, EL Bartlett, SG Kujawa - Neuroscience, 2019 - Elsevier
Aging listeners often experience difficulties in perceiving temporally complex acoustic cues

Aging alters envelope representations of speech-like sounds in the inferior colliculus

A Parthasarathy, B Herrmann, EL Bartlett - Neurobiology of aging, 2019 - Elsevier
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 …
