Effect of rotating acoustic stimulus on heart rate variability in healthy adults.

Acoustic stimulus can modulate the Autonomic Nervous System. However, previous reports on this topic are conflicting and inconclusive. In this study we have shown, how rotating acoustic stimulus, a novel auditory binaural stimulus, can change the autonomic balance of the cardiac system.

Moving sound reduces arousal in psychosomatic patients.

The present study was designed to investigate the possible effect of moving sound stimulation on Galvanic Skin Response (GSR) in psychosomatic patients. Sixteen volunteers (psychosomatic = 8, healthy controls = 8) were exposed to a moving or stationary sound of same acoustic structure while GSR was monitored. Results indicated that moving sound produces a significant reduction of arousal in psychosomatic patients.
