Auditory Prosthesis Laboratory

Li Xu, M.D., Ph.D.

Associate Professor and Lab Director

The goal of research in this laboratory is to understand the mechanisms of hearing and speech perception under electrical stimulation and thus to find ways to improve speech and music perception in patients with cochlear implants. We study speech and music perception in patients with cochlear implants and in normal-hearing subjects using acoustic simulations. Current research projects include spectral and temporal features of stimulation for phoneme perception and for lexcial-tone perception, tone development in children, and melody perception.

This laboratory is equipped with the clinical cochlear-implant programming systems from Cochlear Corporation and Advanced Bionics Corporation. It also has a TDT System 3 for psychoacoustics and neurophysiology experiments. A sound-attenuating booth and computers that are used for control of sound delivery and for data collection and analysis are in place. The research in this laboratory is supported by both internal and external grants. Collaboration with Kresge Hearing Research Institute at University of Michigan, Seoul National Unviersity, Beijing Tongren Hospital/Beijing Institute of Otorhinolaryngology (Capital Medical University) , Each China Normal University, and Shanghai Jiaotong University and has been established.

Inquiries about opportunities for Au.D. studies should be addressed to Sally Marinellie, Ph.D., Coordinator of Professional Programs, School of Rehabilitation and Communication Sciences, Grover Center - W218, Ohio University, Athens, OH 45701.
