Comparison in New Cochlear Implanted Subjects of a Tonotopy-based Bimodal Fitting With or Without Synchronization

Recruiting now · Not applicable

Conditions studied: Sensorineural Hearing Loss, Bilateral

In brief

Main objective: For a bimodal fitting (hearing aid (HA) + cochlear implant (CI)): Comparison of a tonotopy based fitting strategy with synchronization between HA and CI (ABFS) to a tonotopy based fitting strategy without synchronization (ABFnoS) for the accuracy of sound localization. Secondary objectives: Comparison of ABFS to ABFnoS for the bias of sound localization. Comparison of ABFS to ABFnoS for speech perception in noise. Comparison of ABFS to ABFnoS for the auditory skills experienced by the subject.
