Sound source location is encoded by distinct dynamic binaural cues

Evidence

Predators like the barn owl (Tyto alba ) will routinely hunt moving prey, and they perform in-flight corrections (Hausmann et al. 2008 ). Thus, with respect to sound source localization, real world situations confront the auditory system with varying binaural cues. Possible motion-related dynamic binaural cues are the change in interaural time differences (ITDs), in interaural level differences (ILDs) or in spectral peaks and notches. Generally, ITD cues identify sound source azimuth, ILD cues azimuth and/or elevation and peaks and notches mostly elevation (e.g., Grothe et al. 2010 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 3181
