Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or intensity difference) between the ears, and spectral informatio… WebThe brain uses interaural, time, amplitude, frequency and phase differences to locate sounds. In the case of the sounds coming from behind you versus those in front of you, time, phase, and amplitude will be equal at both ears for the most part. However, there is a frequency difference due to the pinna effect.
