This paper describes correlation between the subjective evaluation by using visual analog scale (VAS) and acceleration plethysmography analysis (APG) for the effects of the 1/f fluctuation music. The experiment employed 23 healthy subjects. APGs of the subjects are recorded when they listen to the 1/f fluctuation music and when they listen to nothing. Furthermore, in order to investigate the psychological state change, the subjects are required to answer VAS questionnaire for both cases (listening to the 1/f fluctuation music, and not). The experiment results shows that there exists relationship between VAS data and APG data.
