Research Interests:

A major focus our research is to relate basic aspects of human auditory perception to auditory physiology. An example is our continuing work on the “dynamic range problem”- how useful auditory perception over a huge dynamic range (120 dB) is mediated by auditory nerve fibers whose dynamic range typically is restricted to 30 dB. Our behavioral research on this fundamental problem has led to the development of provocative computational models of multiple aspects of auditory processing. We also have continuing research projects on other basic aspects of audition. These include projects on temporal processing, binaural hearing, pitch coding , and speech perception.

Most of our experimental research involves behavioral studies on persons with normal hearing. We also have collaborative research projects on the perceptual consequences of hearing loss and on the basic auditory capabilities of persons with cochlear implants. One goal of these projects is the development and refinement of auditory prosthetic devices. Another goal is to use these “abnormal” auditory systems to provide insights into normal auditory processing. Overall, the general goal of our research is to understand the biology and psychology of hearing.
