Natural hearing in the wild involves constantly changing binaural cues rather than static ones

Evidence

Our auditory world is by no means stationary. Natural sound sources often change position and also listeners move in their environment. 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…, 3183
