See information for Patients. Viewing information for Researchers.

Dr. David A. Eddins' research in auditory perception includes foci on the perceptual consequences and underlying mechanisms associated with age related hearing loss, characterization of spectro-temporal processing in listeners with normal and impaired hearing, signal processing to improve speech perception and sound quality in hearing aids and cochlear implants, auditory perception of the pathological voice, behavioral and electrophysiological correlates of auditory perception, and development of new signal processing algorithms and systems for hearing enhancement.

Dr. Eddins earned a PhD in experimental psychology from the University of Florida, and is a certified Clinical Audiologist with extensive experience as a clinical and research Audiologist. Dr. Eddins has held the position of Research Audiologist at the Long Beach Veterans Administration Hospital and the University of North Carolina Hospitals. From 1994 to 1999 he was Assistant Professor in the Department of Speech and Hearing Sciences at Indiana University. In 1999, he joined the faculty at SUNY at Buffalo where he was Director of the psychoacoustics laboratory and the Clinical Hearing Research Center. Dr. Eddins is an Associate Professor in the Department of Otolaryngology, University of Rochester, and the senior scientist at the International Center for Hearing and Speech Research at the Rochester Institute of Technology. Dr. Eddins' research interests include auditory perception, presbycusis, hearing aids, cochlear implants, diagnostic audiology, perceptual correlates of auditory evoked potentials, and auditory perception of the pathological voice.
