Abstract : The paper discusses the effect of audio sound pattern, intensity and frequency on human visual depth perception and visual discrimination ability. The depth perception ability of fifteen subjects that were used in these experiments was not significantly affected by the experimental variables. Visual discrimination ability was degraded by the experimental variable of 400 cps. sinusoidal sound between 80 and 110 decibels. The degradation was .205 seconds and may have an effect on human performance in situations where activity involving high speeds is present. (Author)
