Pinna and concha resonance determine front-behind sound localization

Evidence

Sound localization is helped mainly by the acoustic effect of the pinna and the concha. The concha acts as an acoustic resonant cavity. The com­ bined acoustic effects of the pinna and concha are particularly useful for determining whether a sound source is in front or behind, and to a lesser extent whether it is above or below. — David Howard, Jamie Angus, coustics and Psychoacoustics, 517
