Problem:
Pretty self descriptive, without being able to view the source of the noise how can we tell the difference between a sound in front of us and a sound behind us if pitch, volume and distance are all the same.
Also assume that it is not biased to one side more than the other, e.g its not to your left or right but directly in front or behind.
I'm interested in knowing if it is a part of the ear that makes this distinction, or a function of the brain.
Could someone help to explain the answer of these question.
