The Auditory Evoked Potentials Laboratory includes two research spaces. One is located in the Wendell Johnson Speech and Hearing Center and the other in the Department of Otolaryngology at the University of Iowa Hospitals and Clinics (UIHC). Both are equipped with instrumentation necessary to record and analyze a wide range of auditory evoked potentials from normal-hearing and hearing-impaired listeners as well as cochlear implant users.

Our goal is to evaluate the extent to which evoked potentials can be used to predict performance on a range of different listening tasks and to expand our understanding of how acoustic and electrical signals are processed in the peripheral auditory system.  Funding comes from a variety of sources including more than 30 years of funding by the National Institutes of Health (NIH).

Our lab also works closely with audiologists from the Wendell Johnson Speech and Hearing Clinic as well as from the Otolaryngology / Audiology and Cochlear Implant Clinics at UIHC. Examples include collaborations with Richard Smith MD ( as well as animal studies conducted by Marlan Hansen, MD (
