Research and Teaching Interests

Dr. Doherty specializes in speech perception in the hearing-impaired, psychoacoustics, and amplification, with a specific interest in improving hearing aid fitting protocols for older people. Dr. Doherty is a Gerontology Faculty Affiliate since 2007.

Research Spotlight

doherty-sidebar.jpg

Our research is focused on improving hearing communication for older people. We study the effects of cognitive aging and age related hearing loss on people’s ability to perceive speech. In our studies we focus on both the effects of bottom up (peripheral hearing) and top-down (central processes) processing on older people's ability to perceive speech and successfully use hearing aids. The long-term goal of our work is to increase the benefit and satisfaction that older people receive from wearing hearing aids and using other assistive listening devices.
