The goal of this study is to study the adaptation process in newly implanted Single-Sided Deaf Cochlear Implant (SSD-CI) users. Subjects will use four frequency maps for the first month after CI activation. One of these maps will be standard of care and the other three will have higher low frequency edges than the standard of care default maps. These maps will alternate daily during the first month (with exceptions made for situations when the subject is allowed to use a preferred map rather than the map predetermined for use that day), and after that point each subject will make a selection at the beginning of the week to compare all four maps and decide which one to use at the beginning of the following week. The goal of this study is to investigate how reducing place-pitch mismatch in SSD CI users affects 1) sound quality, 2) device use, and 3) speech perception.

RECRUITINGBilateral speech perception as measured by Bamford-Kowal-Bench (BKB-SIN) speech-in-noise score while using standard 188 Hz Frequency-Allocation Table (FAT)
The BKB-SIN speech-in-noise test measures speech perception in noise by assessing a listener's signal-to-noise ratio (SNR) loss. The test results are presented as the SNR loss, which is the amount the signal-to-noise ratio needs to be increased for the listener to correctly repeat 50% of the sentences. A higher SNR loss indicates more difficulty hearing.

Sound Quality Survey score while using standard 188 Hz FAT
The Sound Quality Survey records subjective thoughts regarding sound quality, listening effort and intelligibility with all four maps at various time points. The survey was created for this study and consists of 4 questions address speech understanding, listening effort, sound quality, and music when the CI is ON versus when the CI is off. Items are rated from 1 (worst) to 9 (best). Scores range from 4-36, higher scores indicate better overall sound quality when the CI is on. Participants will provide a separate answers for each of the 4 maps.
