Effect of bilateral and unilateral continuous and impact noise on equilibrium as measured by the rail test.
J Appl Psychol 1976 Feb; 61(1):123-126
Description is given of an experiment designed to determine whether the unbalanced stimulation of the two ears impairs the ability to stand on rails with eyes open would hold in a natural free field situation, such as might exist in a real industrial environment. A preliminary experiment with 18 subjects standing with eyes open or closed in bilateral or unilateral noise indicates that there are no effects of noise on equilibrium. A second experiment involving monaural stimulation of 10 subjects under identical conditions to one of Harris's experiments also indicates no impairment by noise. Possible explanations of the inconsistent findings are discussed. (Contract No. 099-73-0022)
