Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Eighteen years of age or older at the time of the study.
* Postlinguistic onset of bilateral severe-to-profound sensorineural hearing loss
* Bilateral severe-to-profound hearing loss that meets current cochlear implant criteria (\<50% open-set sentence recognition in quiet scores in the ear to be implanted and \<60% in the best-aided condition)
* English spoken as the primary language.
* Willingness to participate in and to comply with all requirements of the study
* Subject may receive bilateral simultaneous cochlear implants.

Exclusion Criteria

* Previous cochlear implant experience
* Congenital hearing loss (for the purpose of this study, onset prior to 2 years-of-age).
* Ossification, absence of cochlear development or any other cochlear anomaly that might prevent complete insertion of the electrode array.
* Normal hearing in one or both ears.
* Hearing loss of neural or central origin (e.g., deafness due to lesions on the acoustic nerve or central auditory pathway).
* Active middle-ear infection.
* Unwillingness and/or inability of the candidate to comply with all investigational requirements including, but not limited to, study protocol and surgical procedure.
