Inclusion criteria

Newly implanted and existing recipient Groups (Groups 1 and 2): * Age 12 and older * Monosyllabic word score administered at 60dBA (2 lists) with an appropriately fit hearing aid in the ear to be implanted who are receiving a cochlear implant as standard of care * Group 2: 3 months or greater combined experience with commercially available sound processors * Fluent spoken English skills

Exclusion criteria

* Unrealistic expectations on the part of the subject regarding the possible benefits, risks, and limitations * Additional cognitive, medical or social handicaps that would prevent completion of all study requirements as determined by the Investigational team * Unwillingness or inability of the subject to comply with all investigational requirements * Use of an acoustic component in the implanted ear * Less than 18 active electrodes * Hybrid L Cochlear Implant

MeasureTime frameDescription
Change in Monosyllabic Word Recognition Scores (CNC) in QuietPre-operative/Visit A; Group 1: 6 months; Group 2: 1 monthMonosyllabic word recognition was scored in quiet using Consonant-Nucleus-Consonant (CNC) words. Scores are listed as percentage correct thus a higher score (percentage) means a better outcome.Group 1: Preoperative to postoperative percentage performance after 6 months of cochlear implant use. Group 2: Visit A to Visit B after 1 month of cochlear implant use.
