Binocular vision gives a perception of distance through the coördination in the brain of sensations coming from the two retinas and the two sets of ocular muscles. In a somewhat comparable way, one determines whether a sound comes from the right or left side by the coordination of sensations coming from the ears.

The segments of concentric circles represent sound waves.The listener, D, knows that the sound is on his right side, for two reasons. In the
