Interaural time difference (itd): the difference in time between a sound arriving at one ear vs. the other. Azimuth: the angle of a sound source on the horizontal plane relative to a point in the center of the head between the ears: measured in degrees: 0o = straight ahead, 180o = directly behind. Itd is largest when sound source is at 90o and 270o (directly left or right: can vary depending on size of head. Medial superior olive (mso): a relay station in the brain stem where. Physiology of itds inputs from both ears contribute to detection of the itd: found neurons in the msos whose firing rates increased in response to very brief time differences between inputs from the two ears of cats. Physiology of ilds from both ears contribute to the detection of ild. Lateral superior olives: relay station in the brain stem where inputs.
