Document Summary

Inter-aural time differences: if a sound comes from the right, it will hit the right ear before the left ear. Works better with low frequencies because there is a bigger time difference between the top and bottom of the wave. Inter-aural level differences: works better for high frequencies, acoustic shadow. high frequency sound waves wrap right around shadow, whereas low frequency waves will get blocked by the head the head, low acoustic. If something is equally loud in both ears (sound arriving at same time), the sound is likely coming from in front or behind you. you can know for sure by turning your ear in both directions (front, back) Spectral cues: the farther away the sound, the less sound will reach the ears. Complex tone: will have fundamental, and harmonics (most sounds). the high frequencies tend to dissipate before the low frequencies, do not travel as well.
