About the Facility 

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 the following areas: (1) spectral and temporal features that contribute to speech perception and lexical-tone perception, (2) lexical tone development in children in real-world situations, and (3) nonlinear frequency compression for Mandarin fricative recognition. This laboratory is equipped with the clinical cochlear-implant programming systems from Cochlear Corporation and Advanced Bionics Corporation. It also has a sound-attenuating booth and a TDT System 3 for psychoacoustics and neurophysiology experiments. The research in this laboratory is supported by both internal and external grants.
