Comparison of Anatomy-Based and Standard Fittings for Adults Using Bimodal Cochlear Implants and Hearing Aids

What this Trial Is About

Researchers are investigating how an anatomy-based fitting compares to a standard fitting for adults who use bimodal hearing devices, which include a cochlear implant and a hearing aid in the opposite ear. The study focuses on evaluating speech perception in quiet and noise, discrimination of consonants and vowels, and perception of pitch and timbre to better understand the benefits of these fitting approaches. Participants will experience two fitting methods for their cochlear implant speech processor the anatomy-based fitting and the default standard fitting used in clinical care. The study uses a randomized crossover design where participants receive both fitting types in different sequences during a single study visit to directly compare their effects. During the study visit, participants will undergo several hearing tests including speech recognition in quiet and noise, vowel and consonant identification, and pitch and timbre ranking. These tests will be performed after each fitting type is applied. The primary outcome measured is speech recognition in quiet immediately after intervention. All assessments occur in one day with no extended follow-up period.
