Goldsworthy, Ray

Ray’s research combines psychoacoustics, signal processing, and auditory rehabilitation towards improving hearing for the hearing impaired with emphasis on cochlear implant technology. Ray’s research examines relationships between fundamental limits of auditory resolution with speech recognition. This line of research provides a foundation for quantifying auditory capacity, and sets the stage for systematically exploring signal processing solutions to enhance hearing for the impaired. Ray’s signal processing research focuses on strategies that are inspired by the dynamic processes observed in healthy hearing. These strategies range from spatial beamformers modeled after binaural hearing to cochlear implant stimulation strategies inspired by auditory nerve physiology. Combining psychoacoustics and signal processing ultimately requires careful attention to auditory rehabilitation since cochlear implant and hearing aid users generally require dedicated time and training to learn how to use new information provided by enhanced signal processing solutions.
