How to localize direction / source of sound?
By role of importance: -
1st - Inter-Aural Time Difference (ITD) = which sound that reach first is the source of direction.
2nd - Inter-Aural Intensity Difference (IID) - which sound is louder, fools the ear & brain to perceive as source of direction.
3rd - Head-Diffraction, l, shadow effect.
This is high frequency, little perception to the opposite ear, precedence priority given to the exposed ear as high probability of source of direction.
But at low frequency, where the wavelength = l, is "relatively" large, sufficient to envelope both ears, also normally with equal strength???, therefore making localization difficult. In this case, un-conscious mode engage and relies on higher harmonics to Q the source of direction, including the use of ITD and IID above.
