Narrowband and Broadband Envelope Cues for Aural Classification

Abstract

Auditory classification of a set of brief sounds was compared to that in a number of conditions that manipulated the spectral and temporal information in the signal. Multidimensional scaling techniques identified the use of six perceptual dimensions that could be accounted for by amplitude-envelopes of critical-band filtered signals. Modulation rates above 200 Hz did not contribute much to classification although there was some suggestion that rates greater than 200 Hz were significant for one of the dimensions. These results indicate the potential importance of envelope information for auditory classification of brief sounds. Auditory perception, Aural classification, Envelope features, Sonar signals.
