The purpose of this paper is to investigate the effect of the sound accompanying the repetitive movement of the step test upon the heart rate and respiration rate during and after the test. The effects of metronomic and musical sounds respectively were examined. The subjects climed up and down a step to the sounds which were set at a regular speed. The height of the step and the speed corresponded to the intensity of the exercise. The results are as follows: 1) The heart rate was higher with metronomic than with musical stimuli when the exercise was intense. The heart rate was lower with metronomic than with musical stimuli when the exercise was not intense. So it could be said that physical responses towards mechanical sounds and towards musical stimuli were different. 2) In all the ten experiments, heart rate and respiration rate were mutually related. The pattern of their increase and decrease, however, were not necessarily the same. 3) Whether the exercise was intense or not, the subjects found musical stimuli more agreeable than metronomic sounds.
