Document Summary
Even though sound travels very fast, the pressure wave will not arrive at both ears at the same time. The intensity of sound is greater at the ear closer to the source. Interaural time difference the difference in time between a sound arriving at one ear vs the other. we tell where a sound is coming from by determining which ear receives the sound first. Azimuth: the angle of a sound source on the horizontal plane relative to a pnt in the center of the head between the ears. It is measured in degrees, with 0 degrees being straight ahead. The angle increases clockwise toward the right, with 180 degrees being directly behind. red circles indicate positions from which a sound will reach the right ear before the left ear; blue circles show positions from which a sound will reach the left ear first. The size and brightness of each circle represent the magnitude of the.
