Sound localization refers to a listener's ability to identify the location or origin of a detected sound in direction and distance. It may also refer to the methods in acoustical engineering to simulate the placement of an auditory cue in a virtual 3D space (see binaural recording, wave field synthesis).
Because of this slowness in the movement of sound waves, your brain is able to help you locate the source of a sound. There is a measurable difference in the time it takes the sound to reach both of your ears. From this you can tell where the source is located. You can use sound to measure distances.
