Document Summary
When we first hear a sound there is an interaural time difference which is defined as the amount of time it takes for sound to reach one ear in before it reaches the other. So for instance when a sound comes from a certain angle on the horizontal plane relative to the center of the head aka azimuth, sound will reach one ear more quicker than it reaches the other ear. As sounds travel through the auditory system there is an area in the brain that receives these signals together at once, and this area is called the medial superior olive aka itd detectors. Another factor is known as the interaural level difference, which is defined as the difference in level intensity between a sound arriving at one ear vs. the other. Because sounds become less intense with greater distance.
