This research deals with the participation of the musical environment of subjects to the physiological and psychological effects of the ultrasonic waves produced by Japanese traditional music, considering about subject’s taste and their musical context. Experiments were conducted with the group of experienced and non-experienced subjects and were examined with (FPS)/without (LPS) ultrasonic waves. In the analysis, behaviors of α waves in whole brain and in temporal lobe, and further, right part and left part were compared with each other. As the result, it is observed that the ultrasonic waves activate the α waves of the whole brain and temporal lobe. And the effects of the ultrasonic waves produced by the music are differently to the music-experienced subjects and to the non-experienced subjects. The mental perspiration was seen more decrease by the music-experienced subjects than by the non-experienced subjects. In the psychological analysis, the impressions of the difference between FPS and LPS are not equivalent in the 2 groups of subjects. Then it is suggested that the music-cultural context of the subjects participate to the effects of the ultrasonic waves in the music.
