Adult Single-sided deafness
Adult subjects with unilateral single-sided deafness at least 6 months (to ensure stability of hearing loss), but no greater than 10 years will be implanted with a MED-EL Synchrony Cochlear Implant.
Device: Cochlear Implant
adults with unilateral hearing loss who wish to regain bilateral hearing will be implanted with a cochlear implant on their deafened ear.
Other Name: MED-EL Synchrony
- Change in AzBio Sentences in Noise [ Time Frame: Pre-operative baseline, 3, 6, 12 months post-activation ]The percent correct of words from a list of 20 Target AzBio sentences will be played from 0° azimuth. A list of AzBio sentences will be played in multitalker babble which will be presented in three different conditions: 0° azimuth, S0N90, or S0N270°.
- Change in Localization [ Time Frame: Pre-operative baseline, 3, 6, 12 months post-activation ]Testing with 16 sounds played randomly from 1 of 8 loudspeakers in a 108 degree arc will be completed with non-implanted ear alone and everyday listening condition at 60 dBA. Subjects will be asked to identify which loudspeaker presented the sound. The RMS error in degrees will be calculated. A lower number indicates better localization ability.
