RESEARCH SUMMARY
Our recent work is aimed at developing a better understanding of the perception of complex sounds. The auditory periphery may be modeled as a graded frequency analyzer, splitting the incoming sound into 'frequency channels'. We employ psychophysical experiments in an effort to examine the means by which information is combined across frequency channels (and across ears) in order to form a single percept. The experiments employ digitally generated stimuli, allowing systematic control of the physical properties of the stimulus, and also allowing the effects of a target parameter to be measured. Human performance is then evaluated relative to mathematical/statistical processing models.
