ch 129 Perceptual organization Grouping in music? Demonstration –Structure in music

ch 1210 Demonstration Listen to music (Beethoven, symphony #5) Listen to music (Norah Jones “Don’t know why”) Listen to music (Lauryn Hill)

ch 1211 Sound localization Demonstration: –Where does this sound come from? –YouTube Ventriloquist (America's Got Talent) &q=ventriloquist&total=239 8&start=0&num=10&so=0&type=search&plindex= 4

ch 1212

ch different coordinates –The horizontal coordinate –The elevation coordinate –The distance coordinate

ch 1214 Figure 12.2 Measurements of sound localization ability. Red squares indicate the actual sound locations, and the circles are the listeners ’ estimates of their location. Longer lines connecting the squares and circles indicates less accurate localization.

ch 1215 Identifying the sound source in the horizontal coordinate Interaural differences –Interaural time differences Capture the difference in the time that a sound reaches the left and right ears –Interaural level differences Capture the difference in the level of the sound intensity (sound pressure level) that a sound reaches the left and right ears

ch 1216

ch 1217 Identifying the sound source in the elevation coordinate Spectral cues –Capture the way the head and pinnae affect sound frequencies

ch 1218 Depending on the level of elevation, the same sound enters the ears in a different manner.

ch 1219 Information about distance Different sound levels Frequency –atmospheric perspective (vision) –The quality of sound (frequency) is modified by the atmosphere. Movement parallax –The nearby sound moves quickly than the far away sound. Direct sound vs. reflected sound –Nearby sound tend to be direct, distant sound tends to be indirect

ch 1220 The physiological basis for localization Interaural time difference detectors –E.g., a neuron that responds best when a sound reaches the left ear first and the right ear (vice versa) 1 millisecond later.
