Abstract
This paper describes correlation between the subjective evaluation by using visual analog scale (VAS) and heart rate variability (HRV) for the effects of the 1/f fluctuation music. The experiment employed 21 healthy subjects. HRVs of the subjects when they listen to the 1/f fluctuation music and when they do not, are recorded separately. 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). When the subjects listen to the l/f fluctuation music, their LF/HF values are decreased. And the experiment result shows that there exists relationship between VAS data ("Like or Dislike") and HRV data. Therefore, the proposed method is very useful.
