Summing localization occurs when two or more coherent
sound wave
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid.
In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the ...
s arrive within a limited time interval and only one sound sensation is perceived. If the time variations are smaller than 1 ms, the time and level variations of all sound sources contribute to the direction of the perceived sound. The resulting
auditory event is called a phantom source.
Summing localization is the basis of
stereophony
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration ...

Precedence effect
The precedence effect or law of the first wavefront is a binaural psychoacoustical effect. When a sound is followed by another sound separated by a sufficiently short time delay (below the listener's echo threshold), listeners perceive a single ...
