Dr. Hellman's research is concerned with mathematical and computational modeling of signal detection and neural-processing mechanisms in the auditory system. The input for the analyses are data from psychophysical and physiological studies. The present focus is to understand loudness coding and its relationship to intensity discrimination in normal and abnormal hearing.
