Document Summary
Thus, there are two potential types of information for determining the source of a sound: first, even though sound travels fast, the pressure wave will not arrive at both ears at the same time. Sound arrives sooner, albeit very slightly, at the ear closer to the source: second, the intensity of a sound is greater at the ear closer to the source, these are our rst two auditory localization cues. Interaural time difference: interaural time difference (itd): the difference in time between a sound arriving at one ear versus the other, if the source is to the left, the sound will reach the left ear rst. If it"s to the right, it will reach the right ear. Azimuth is measured in degrees, with 0 degrees being straight ahead. The physiology of ilds: neurons that are sensitive to intensity differences between the two ears can be found in the lateral superior olives (lsos), which receive both excitatory and inhibitory inputs.
