Abstract
Claims that infrasound adversely affects human performance, makes people drunk, and directly elicits nystagmus, were not clearly demonstrated in any experimental study. The effects obtained at low intensity levels of 105-120 dB, if they can be substantiated at all, were exaggerated. Recent well-designed studies conducted at higher intensity levels found no adverse effects of infrasound on reaction time or human equilibrium. The levels at which infrasound becomes a hazard to man are still unknown. The hazardous levels are certain to be much higher than have been suggested. The preliminary exposure limits which were proposed several years ago for use in the USA are still considered safe and adequate based on present knowledge. Caution is necessary in future research because artifacts produced by faulty experimental procedures can suggest genuine psychological or physiological effects.
