For many years, Dennis McFadden's research involved psychophysical measurements on various aspects of hearing--sound localization, masking, pitch perception, the aftereffects of exposure to intense sound, auditory adaptation, and comodulation masking, among other topics. In recent years, his interests have turned to more physiological measures of the auditory system, especially otoacoustic emissions (OAEs), which are sounds generated in the inner ear and monitored using a sensitive microphone system placed in the ear canal. Initially, Dr. McFadden was interested in the heritability of the individual differences observed in OAEs and that led to an interest in the sex differences seen in OAEs (females have more and stronger OAEs than males). While searching for possible explanations for the sex differences in OAEs, Dr. McFadden discovered that OAEs are atypically expressed in certain special populations of subjects.

In 1984, he received a five-year Jacobs Javits Neuroscience Investigator Award from the NIH, in 1987 he was awarded a Piper Professorship, and in 1998 UT made him an Ashbel Smith Professor in Experimental Psychology. Dr. McFadden has been a member of the Executive Committee of the UT Institute for Neuroscience since 1985, and he recently became a member of the Executive Committee for the UT Center for Perceptual Systems. He has served as Associate Editor for Psychological Acoustics for the Journal of the Acoustical Society of America, and his research has been continuously funded by NIH since 1969.
