The Hearing Science Laboratory houses studies focusing on improving understanding of hearing and hearing loss, particularly in the aging population and as it may be affected by environmental noise. This includes studies of the effects of aging on speech perception, growth of masking and other aspects of auditory ability and the relation between speech perception and more basic auditory abilities.  The laboratory has developed a number of improved techniques for assessing speech understanding abilities in both hearing impaired clients and normal-hearing subjects. Tests developed in this laboratory include our Adaptive Speech Reception Threshold (ASRT) test and our Distinctive Features Differences (DFD) test, both of which are used in evaluation studies in our ASL, SCL, and elsewhere.
