Summary

The objective of this study is to investigate benefits of binaural hearing for non-traditional cochlear implant candidates (with Asymmetric Hearing Loss). Asymmetric candidates are patients with severe to profound hearing loss in one ear and better hearing in the other ear. (One ear is deaf and the other ear has better hearing and in most cases uses a hearing aid.) The investigators hypothesize that cochlear implantation of the poorer ear provides a functional increase in word and sentence understanding in quiet or noise, perceived benefit, localization ability, and other measures of auditory performance relative to use of the better hearing ear alone.
