Head movements and pinna shape resolve ambiguous sound localization

Evidence

However, the cone of confusion only exists as long as the head is held stationary. Head movements can resolve ambiguities and allow for improved localization (Wallach, 1940). The asymmetrical and curved shape of the pinnae also assists with resolving the cone of confusion. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1474
