Definition of Phantom center
Phantom center refers to the psycho-acoustic phenomenon of a sound source appearing to emanate from a point between two speakers in a stereo configuration. When the same sound arrives at both ears at the same time with the same intensity, it appears to originate from a point in the center of the two speakers.
A difference in intensity (volume) will cause the sound to appear to come from the louder side. Similarly, if a sound arrives at one ear before the other (no later than approximately 30 ms, see Precedence effect), it will appear to originate from that side.
The ear–brain system evolved to use these cues to determine the location of sounds, an important evolutionary advantage.
