Sound localization is the process of determining the location of a sound source. The brain utilizes subtle differences in intensity, spectral, and timing cues to allow us to localize sound sources. In this section, to more deeply understand the human auditory mechanism, we will briefly discuss about human ear localization theory. WebSep 29, 2024 · Two ears offer a bit of cushion because the sounds are divided between two ears, and this makes it possible to tolerate louder noises. Having binaural hearing helps sudden, loud sounds lose the jarring effects when divided.

"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. " - How do humans localize sound
