Abstract

Introduction: Partially implantable hearing devices have been developed to address some of the user-perceived shortcomings of standard amplification systems. Partially implantable devices are purported to provide improved sound quality as a result of decreased occlusion, decreased feedback, and enhanced clarity resulting from increased high-frequency gain. Such improvements may result in greater user satisfaction. To justify selection of a partially implantable device and undergoing a minor surgical procedure, verification techniques must be used to document user improvement or increased satisfaction over conventional amplification. Objective: To evaluate patient satisfaction with the SOUNDTEC direct hearing system. Study Design: Within-subjects repeated measures design. Methods: Objective and subjective evaluation pre- and post-implantation with the SOUNDTEC device. Verification techniques included tonal functional gain measures with traditional amplification and the SOUNDTEC device, word recognition in quiet (NU-6) and in noise (SPIN), the Abbreviated Profile of Hearing Aid Benefit (APHAB), and the Hough Ear Institute Profile (HEIP). Results: Although there was no significant difference between optimal traditional amplification and the SOUNDTEC device for speech perception measures, the SOUNDTEC device yielded statistically significant increased high-frequency functional gain. Subjective reports indicated that the SOUNDTEC device provides a cleaner, more natural sound without feedback than traditional amplification. Conclusions: Partially implantable hearing aids may address some of the limitations of traditional amplification systems.
