Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to understand the speech perception in noise and in quiet and localization benefits in a laboratory setting in listeners that receive a cochlear implant in an ear with severe to profound hearing loss and have normal, or near-normal hearing in the opposite ear. We will also evaluate the functional benefit of restoring hearing to the impaired ear via questionnaires that subjects will be answering while listening in their natural environment.
