Overview
Brief Summary
Do adults and children over 7 years of age with unilateral or assymetric hearing loss benefit from cochlear implantation on the worst hearing side.
Detailed Description
Unilateral hearing loss is known to impair binaural hearing abilities. Specifically, localization, speech understanding in noise, and binaural squelch suffer due to lack of binaural timing and level cues. This study is designed to examine how binaural hearing is improved following cochlear implantation on the impaired side. The study endpoints are collected at 6 months and 12 months post activation of the implant. This is not a funded study. All costs are billed through insurance for reimbursement. There is an insurance approval process that we move through after a participant has been evaluated at the Mayo Clinic and found to be a candidate for cochlear implantation.

Outcomes
Primary Outcomes
Listening Effort
Time Frame: one year post operative test time
A dual task performance paradigm will be used in which both the primary task and the secondary task will be performed simultaneously. The primary task will consist of speech recognition testing in varying levels of background noise and quiet, whereas the secondary task will consist of a motor reaction to a randomly presented light
