Peripheral and Central Influences on Auditory Temporal Processing & Speech Perception in Older Cochlear Implantees

NCT05554692 · Status: ENROLLING_BY_INVITATION · Phase: NA · Type: INTERVENTIONAL · Enrollment: 300

No results posted yet for this study

Summary

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.

Conditions

  • Hearing Loss
  • Cochlear Hearing Loss
  • Hearing Loss, Sensorineural
  • Aging

Interventions

DIAGNOSTIC_TEST

Diagnostic tests of cochlear implant function

Because the subjects in the study will use CI devices that they have already received as part of their standard-of-care treatment, the medical device itself is not an intervention for the purposes of this study. The intervention here will be to carry out diagnostic tests of CI function. This will include perceptual tests of temporal discrimination and speech understanding.

DIAGNOSTIC_TEST

Diagnostic tests of auditory function

The intervention here will be to carry out diagnostic tests of hearing. This will include perceptual tests of temporal discrimination and speech understanding.
