Clinical Evaluation of Frequency Allocation for Bimodal CI Users

NCT06663917 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 24

Last updated 2025-09-02

No results posted yet for this study

Summary

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.

Conditions

Interventions

OTHER

Experimental frequency allocation table (FAT) - 438 Hz

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.

OTHER

Standard FAT - 188 Hz

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