Lateralization of Transient Signals and Types of Delay

Abstract

Lateralization of narrow-band, low-frequency transient signals can be based on phase delay; however, narrow-band low-frequency signals cannot be lateralized on the basis of group delay. Good lateralization performance with broadband signals apparently based on group delay is determined by phase-delay cues extracted from frequency bands remote from the centre frequency of the signal. Performance is significantly influenced by the magnitude and sign of the interaural phase delay near 650 Hz.
