Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experienced Users

All subjects will be fit with a modified cochlear implant program ("experimental FAT") that changes which frequencies are presented to the cochlear implant. Subjects will complete a 1 month adaptation to the experimental FAT (438 Hz) and then a one month re-adaptation to the standard FAT (188 Hz). Speech perception tests and questionnaires will be collected before and after each FAT adaptation.

Group Type EXPERIMENTAL

Experimental frequency allocation table (FAT) - 438 Hz

Intervention Type OTHER

The modified cochlear implant program ("experimental FAT") changes which frequencies are presented to the cochlear implant. The experimental FAT frequency of 438 Hz will be loaded onto the subjects processor via the CI Select Mobile App. Subjects will use the experimental FAT for one month.

Standard FAT - 188 Hz

Intervention Type OTHER

All subjects will retain one program with the standard 188 Hz FAT. Subjects will use the standard FAT for one month.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age 18 or older
2. Regular usage of a cochlear implant device with at least 18 active electrodes, and compliance with programming/appointments
3. Received a cochlear implant at least 6 months ago and use a hearing aid in the contralateral ear
4. Pure tone average (.5, 1, and 2kHz) between 30 and 70 dB (decibel) hearing level in the contralateral (hearing aid) ear
5. Standard FAT use for all programs prior to study participation
6. No known anatomical abnormalities in either ear
7. English speaking
8. No known cognitive impairments
9. At least 25% of subjects should use the Cochlear EA32 electrode

Exclusion Criteria

1. Under age 18
2. 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.
3. Cognitively impaired
4. Non-consistent device usage
5. Greater than 70 dB hearing level pure tone average in the contralateral ear
6. Normal hearing or mild hearing loss in the contralateral ear
7. Non-standard FAT programs
8. Use of any frequency transposition programming in hearing aid.
