Time-Frequency Factors in Auditory Perception

Abstract

The final report of this year research program summarizes our experimental and theoretical results concerning what we have termed cross- spectral temporal resolution. The experiments measured the measured the sensitivity to variations in several of the stimulus parameters. From these experimental results, three theoretical results have been obtained. The first of these concerns the form of the ideal receiver for cross-spectral temporal resolution of amplitude modulated carries. This model incorporates an auditory- nerve model and is based entirely on point-process statistics. The second of these concerns the form of the ideal receiver for cross-spectral temporal resolution of frequency modulated carriers. This model fails to account for the experimental results, which are, in general, much worse than would be predicted from the model and from simple extension of the amplitude-modulation results. On the basis of this failure, a third general theoretical results has addressed the problem of uncertainty in auditory processing.
