Auditory Lab at CMU


Welcome to the Auditory Lab at CMU!

Director: Laurie M. Heller, Ph.D.

Our research examines the human ability to use sound to understand events happening in the environment. Our perceptual experiments discover acoustic cues that reveal attributes of sound events, and how our knowledge of these cue-attribute relationships influences our recognition of sounds. We have also examined how this knowledge influences which brain regions are recruited during the perception of sound events. Our multimodal experiments have combined hearing and vision as well as asking whether sound affects the gestures we make. Our research on sound localization included teaching naive listeners to learn to extract information from echoes about the surrounding environment. Ongoing work involves the perception of sound categories and the effects of unwanted sounds. Collaborative applications are being developed to test sound recognition in hearing-impaired listeners and to improve the performance of a machine learning system for sound event classification. Applications of this research have the potential to enhance auditory displays, hearing aids, and navigation aids for the visually impaired.
