The goal of the Auditory Perception Laboratory is to measure auditory perception in people with normal hearing, hearing loss, and with tinnitus. We use psychoacoustic techniques coupled with those of quantitative psychology to address the mechanisms responsible for the perception of sound.
At present our research focus includes experiments on masking, spectral-shape discrimination, and detection in listeners with good and impaired hearing. We also apply psychoacoustic techniques to the assessment of tinnitus and use reaction time measures to assess the processes involved in the representation of multiple sound cues. Our recent papers have focused on applying cochlear models to further our understanding of masking data in both normal-hearing and hearing-impaired listeners. We are also developing new techniques to assess and detect tinnitus.
Finally, our spectral-shape discrimination and reaction time experiments are used to elucidate decision processes used by normal-hearing and hearing-impaired listeners for the perception of complex sounds.
