Overview
This research is aimed to help people with bilateral cochlear implants or people with single-sided deafness implanted with a cochlear implant. Our study investigates alternative ways of mapping a cochlear implant to improve binaural abilities. The participants take part in several listening, electrophysiological, and imaging tests that allow us to better match frequency allocation of cochlear implant electrodes across the ears. |
Eligibility
*Adult patients with bilateral cochlear implants
*At least 3 months experience with both implants
or
*Adults with single sided deafness and a cochlear implant in the deaf ear
*At least 3 months experience with the cochlear implant
*Normal hearing in the acoustic ear, mild hearing loss not requiring hearing aids, or hearing loss successfully treated with hearing aids. Thresholds less than or equal to 60 dB HL (250-2000 Hz) or less than or equal to 65 dB HL (4000-8000 Hz).
Study volunteers that meet the inclusion criteria will be invited to visit us in the Washington,
D.C. area for testing.
