The human auditory sense of sound is not equal to all frequencies of sound. Naturally, the sense is more sensitive to higher frequencies of sound than that of lower frequencies. In addition to the above fact, it is well known that the performance of human motor activity is rarely impaired by the auditory noise. Take the above point into consideration, in this paper, we discuss the subject that white noise with high frequencies affects to the subjective whole-body motion intensity through an experimental test. In order to measure an intensity of subjective whole-body motion, in the experimental test, Borg-RPE(rating of perceived exertion) scale and tread-mill as experimental equipment are used. Through the experimental test, we had drawn a conclusion that white noise with high frequencies affects to the motor performance of whole-body motion.
