PSYB51H3 Chapter Notes - Chapter 10: Interaural Time Difference, Sound Localization, Binaural Recording
Document Summary
Having 2 ears are necessary for determining auditory localization. Potential types of information: even though sound travels fast, the pressure waves do not arrive at both ears at the same time, sound arrives sooner (very slightly) at the ear closer to source. Intensity of a sound is greater at the ear closer to the source. Interaural time difference difference in time between a sound arriving at one ear versus the other ear. We can determine if the sound is coming from the right or the left. Azimuth 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 (0 being straight ahead, 180 degrees being directly behind (clockwise to right) Image shows the angles at which sound approaches and where the localization occurs: left ear (red), Medial superior olives (msos) a relay station where inputs from both ears contribute to detection of itds.
