Part of paid clinical trials in College Park, Maryland.

Sponsor
University of Maryland, College Park
Study ID
NCT05554692
Status
Enrolling By Invitation

Conditions

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

Eligibility Criteria

Sex
ALL
Age
18 Years - 85 Years
Healthy Volunteers
Not accepted

Interventions

  • Diagnostic tests of cochlear implant function — DIAGNOSTIC_TEST
    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 tests of auditory function — DIAGNOSTIC_TEST
    The intervention here will be to carry out diagnostic tests of hearing. This will include perceptual tests of temporal discrimination and speech understanding.

Study Details

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.

Arms

  • Experimental: Enrolled Participants - Older adults with cochlear implants
    Individuals who already use at least one cochlear implant.
  • Other: Enrolled Participants - Adults with typical hearing
    Control group to provide baseline or comparison data

Primary Outcome Measure

Perceptual forward-masking recovery [ Time Frame: 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. ]
