Older adults who use cochlear implants to address hearing loss show wide variation in benefit. This research investigates the role of normal aging, the health of peripheral and central auditory pathways, and positioning of the cochlear implant electrode array in contributing to this variability. A range of input types from simple auditory signals to spoken sentences is used to examine these questions.

Perceptual forward-masking recovery
Timeframe: Post-treatment - after at least 1 year use of a cochlear implant if CI user. No required time frame for NH comparison listeners. This measure will be collected once within a 6-month time period for each participant.
Perceptual gap detection thresholds
Timeframe: Post-treatment - after at least 1 year use of a cochlear implant if CI user. No required time frame for NH comparison listeners. This measure will be collected once within a 6-month time period for each participant.
Perceptual duration discrimination thresholds
Timeframe: Post-treatment - after at least 1 year use of a cochlear implant if CI user. No required time frame for NH comparison listeners. This measure will be collected once within a 6-month time period for each participant.
Perceptual amplitude discrimination thresholds
Timeframe: Post-treatment - after at least 1 year use of a cochlear implant if CI user. No required time frame for NH comparison listeners. This measure will be collected once within a 6-month time period for each participant.
Speech perception
Timeframe: Post-treatment - after at least 1 year use of a cochlear implant if CI user. No required time frame for NH comparison listeners. This measure will be collected once within a 6-month time period for each participant.
Amplitude modulation detection performance
Timeframe: Post-treatment - after at least 1 year use of a cochlear implant if CI user. No required time frame for NH comparison listeners. This measure will be collected once within a 6-month time period for each participant.
