Fitting of the Hearing System Affects Partial Deafness Cochlear Implant Performance

Introduction Previous experiments have demonstrated that optimal Electro-Acoustic Stimulation (EAS) fitting parameters differ when both electric and acoustic stimulation are used together compared to the ideal parameters when these stimulation modalities are used individually. The goal of the study was to find the optimal EAS benefit and to determine the benefit of hearing preservation in the implanted ear using the DUET audio processor. To the authors’ knowledge, this study has not been performed.
