The Audiology Research Laboratory (ARL) has been in existence since 1978, first residing at Vanderbilt University (1978-1986), then moving to Indiana University in June 1986. The laboratory has consistently focused on behavioral research with adults, both those with normal hearing and those with impaired hearing. Research in the ARL is centered on behavioral measurement of various aspects of auditory perception for simple and complex sounds, including speech.
