Abstract
Radial motion of the auditory image (approach or withdrawal) was modeled with the help of two loudspeakers placed at different distances from the listener in the anechoic chamber. The thresholds of sound duration for image motion and differential thresholds for its velocity at various azimuthal angles were studied. At azimuthal angles of 0°, 30°, 45°, and 60°, the threshold values of the stimulus durations were 150–200ms. At an azimuthal angle of 90° from the head midline, it increased by about 25–30% as compared to other angles. In the case of monaural listening to the signals by unilaterally deaf subjects, the threshold durations of the sound signals were two to three times higher as compared to healthy subjects. Differential thresholds for calculated velocity of the radial motion have been measured within the range 0.4–1.0 m/s, increasing with increase of the standard velocity from 3.4 to 6.9 m/s.
