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.
