Sound source localization is paramount for comfort of life, determining the position of a sound source in 3 dimensions: azimuth, height and distance. It is based on 3 types of cue: 2 binaural (interaural time difference and interaural level difference) and 1 monaural spectral cue (head-related transfer function).
Subsequently, one may also ask, what are the three cues that help you determine the position of a sound?
The auditory system uses several cues for sound source localization, including time- and level-differences (or intensity-difference) between both ears, spectral information, timing analysis, correlation analysis, and pattern matching.
Also Know, what are binaural cues? binaural cue. any difference in the sound arriving at the two ears from a given sound source (interaural difference) that acts as a cue to permit auditory localization.
Considering this, how do we locate sound?
Working together, your two ears can detect a sound’s origin. Having two ears–binaural hearing–allows us to locate the horizontal origin of a sound. Sound coming from the right or the left reaches one ear before the other. Our brain uses this timing difference to find the direction of the sound source.
Can you tell where sound comes from when blindfolded?
If a sound is closer to one of your ears, it is louder. Your brain then thinks “Oh, now I hear the car more on my left side, but the sounds are getting more soft, so the car must be moving away from me to my left.” Yes, your brain will do this even if you are blindfolded, and you don’t really see the car at all.
