Having the ears being able to hear millisecond differences in sound
arrival times is key to our ability to hunt and evade predator's.
We tell the direction of sound at frequencies above about 700Hz, I think
it was, by the change in timbre as the sound has to negotiate the shape of
our ears and heads. This works better for complex sounds than for pure
tones.
This also works less well for lower frequencies, since the wavelength
becomes long enough to diffract around our heads much more easily. We may
be able to tell direction at these frequencies based on phase differences,
or we may not. Certainly home-cinema designers don’t seem to consider this
important, which is why we only have one subwoofer in a typical surround
setup, instead of a stereo pair.
