Bio

My research examines the human ability to use sound to understand what events are happening in the environment. My perceptual experiments address whether there are acoustic cues that reveal attributes of sound events, and how our knowledge of these cue-attribute relationships influences our discrimination of sounds, labeling of sounds, and even gestures. I have also examined how this knowledge influences which brain regions are recruited during the perception of sound events and whether audition plays a significant role in the perception of multi-modal events. Current questions include how listeners can learn to extract the information that echoes contain about the surrounding environment. This basic research relates psychological performance to acoustic properties and high-level auditory information. At an application level, the results of this research have the potential to enhance hearing aids, auditory displays, and navigation aids for the visually impaired.
