Pamela Souza

Pamela Souza directs an active laboratory whose members study aspects of aging, cognition, and speech perception, supported by funding from the National Institutes of Health. Her research interests include how individual hearing and cognitive abilities affect response to hearing aid signal processing, changes in hearing and cognitive abilities with age, communication in adverse (reverberant and noisy) environments, and the benefits of auditory training. Dr. Souza is a Fellow of the American Speech-Language-Hearing Association and serves on the Psychoacoustic and Perception Technical Committee of the ASA. She is a practicing clinical audiologist with focus on working with individuals with severe hearing loss, or who have had limited success with previous hearing aids.  Her professional interests also include hearing assistive technology and tinnitus.
