Hearing Aid Technologies and Outcomes for Adults Lab

About the Lab

The Hearing Aid Technologies and Outcomes for Adults (HATOA) lab examines how hearing aid technologies are related to outcomes for adults who use hearing aids, including preference, speech understanding, loudness, sound quality, and spatial hearing. The HATOA group of investigators is a dynamic, interdisciplinary collaboration that includes audiologists, hearing scientists, and engineers.
