Abstract
The effect of a sound stimulus on postural responses was studied in five subjects (four females and one male). Sound stimuli were noise signals successively applied to loudspeakers placed along an arc, simulating movement of a sound source. A subject stood on a platform centered relative to the arc so that the sagittal plane of the subject coincided with the plane of the arc. Stabilograms of the body's general center of gravity (GCOG) were recorded for 15 s, including 6 s of silence, auditory stimulation (1.6, 3.2, or 4.8 s), and silence after the signal was cut off. A slight decrease in the amplitude of displacement of the GCOG was observed during auditory stimulation. For a signal duration of 4.8 s, a slight forward shift of the GCOG was observed in the sagittal plane, in which the auditory image moved.
