title: [Characteristics of sound source movement perception as a basis for acoustic vertical construction].
abstract: The subject of inquiry was perception of moving sound along the vertical at various angular velocities. The sound was switched around by 13 sequential dynamics installed on a 180 degrees arc. Threshold values for discriminating angular velocities at 150, 167, 188, 214, 250, 300, 375, and 500 degrees/s were measured with the minimal borderlines method. Six test-subjects with normal hearing participated in the experiment. Acceleration of sound movement in the range from 167 up to 500 degrees/s leads to essentially linear increases in absolute threshold values and monotonous increases in relative threshold values.
