Document Summary
Having two ears is crucial for determining auditory locations. For most position in space, the sound source will be closer to one ear than the other. Thus, there are two potential types of information for determining the source of a sound. First, even though sound travels fast, the pressure waves do not arrive at both ears at the same time. Second, the intensity of a sound is greater at the ear closer to the source. These are our first two auditory localization cues. Interaural time difference: interaural time difference (itd) is the difference in time between a sound arriving in one ear versus the other. Thus we can tell whether the sound is coming from our left or right, by determining which ear receives it first. The term that is used to describe locations on an imaginary circle extending around us in a horizontal plane front, back, left, right is azimuth.
