Study Summary
The current standard of care for cochlear implants (CI) does not address the significant pitch-place mismatch that is inherent in cochlear implantation (see detailed description below). The present study uses postoperative Flat Panel (higher resolution than standard) CT imaging to measure where CI electrodes sit within an individual's cochlea; doing so allows for more accurate frequency mapping (and thus pitch perception). The hypothesis of this study is that long-term (1 year) use of CT image-based frequency maps, beginning on the first day of CI activation, will improve user performance in the areas of speech and music perception, as compared to the use of default programming settings.
Primary Outcome
* The CNC word test consists of lists of monosyllabic (single syllable) words with equal phonemic distribution across lists. There are 50 words per list. Performance is calculated based on percentage of words correct (from 0 to 100) and/or percentage of phonemes correct (from 0 to 100). * From CI activation until \~12 months post-activation the participant will use the CT-based program. At that time the participant will "switchover" to the clinical default program, which will be used for \~1 mon
