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
Pure tone average (.5, 1, and 2kHz) between 30 and 70 dB (decibel) hearing level in the contralateral (hearing aid) ear
Disqualifiers
Under age 18
Non-English speaking. Participants that are Non-English speaking are excluded from this study due to the use of speech testing materials that are validated in the English language. Additionally, study team members are not equipped to appropriately score speech testing materials validated in other languages.
