1) In general, human brains etc. are pretty good at localizing sound. Not
as good as owl brains, but not totally incompetent.
2) If the horn has a fundamental frequency of 350 Hz, it most likely will
have significant energy in the 3rd and 5th harmonics, making the
phase-detection job easier.
3) In addition to the phase variations, there will also be volume
variations, because of the directional properties of the pinnae et cetera.
