Abstract

This paper presents a simple model for the extraction of a sound localization cue utilizing pitch cues in the auditory system. In particular, the extraction of the interaural time difference (ITD) as the azimuth localization cue, rather than the interaural intensity difference (IID), is constructed using a conventional signal processing scheme. The new configuration in this model is motivated by psychoacoustical and physiological findings, suggesting that the ITD can be controlled by the pitch cue in the simultaneous grouping of auditory cues. The localization cues are extracted at the superior olivary complex (SOC) while the pitch cue may be extracted at a higher stage of the auditory pathway. To explore this idea in the extraction of ITD, a system is introduced to feed back information on the pitch cue to control and/or modify the ITD for each frequency channel.
