Our research is motivated by clinical questions. Why do two people with the same hearing loss, fit with the same hearing aid technology, have such different outcomes? What happens when the signal-processing effects of digital hearing aids are combined with an impaired auditory system? What factors contribute to difficulty understanding speech as we age?
In this translational research laboratory, we study how auditory and cognitive abilities vary among individuals, and how hearing aid processing and other auditory recommendations can be better tailored to each patient. Our view of hearing aid fitting is that is it both “bottom-up” (affected by deficits in cochlear processing) and “top-down” (affected by central processing resources and ability to make use of an acoustically deficient signal). Within this framework, our work addresses communication problems associated with hearing loss, with particular focus on hearing devices and clinical decision-making.

We are grateful to have ongoing support for our work from the National Institute on Deafness and other Communication Disorders.
Opportunities for individuals with hearing loss
We are interested in working with individuals with and without hearing loss who would like to participate in research. All of our research participants are compensated for their time and offered counseling about their auditory abilities as part of their involvement in our studies.
Our current projects include:
A clinical hearing aid trial which aims to better customize hearing aids to individual abilities. We are interested in working with adults aged 55 years or older willing to undertake a 3-month hearing aid trial in which they wear hearing aids in their own environments and provide us with feedback about their experiences. Testing before, during and after the trial will be conducted to better understand how individual auditory and cognitive abilities should direct how hearing aids are set. Find out how to enroll!
Adults who are interested in training to help them learn to better understand speech in noise while wearing hearing aids. The goal is to find out whether intensive training can improve your ability to communicate successfully in noise. It involves listening to speech though a loudspeaker, and either identifying what you heard or answering questions about the information. This study requires you visit the Hearing Aid Laboratory 2-3 times a week for several months. Find out how to enroll!
