About this trial
This study will examine experienced, bimodal cochlear implant (CI) patients who receive an alternative frequency allocation table (FAT) to determine how it improves sound quality, device satisfaction, and speech perception abilities with respect to the standard default FAT. The goal of this study is to investigate how improving place-pitch mismatch in bimodal CI users affects 1) sound quality, 2) satisfaction, and 3) speech perception.
Eligibility criteria
Qualifiers
Age 18 or older
Regular usage of a cochlear implant device with at least 18 active electrodes, and compliance with programming/appointments
Received a cochlear implant at least 6 months ago and use a hearing aid in the contralateral ear

Additionally, study team members are not equipped to appropriately score speech testing materials validated in other languages.
