Abstract

This paper describes the correlation between the subjective evaluation by using Visual Analog Scale (VAS) for the effects of the unpleasant sound, and Heart Rate Variability (HRV) analysis. The experiment employed 16 healthy subjects. HRVs of the subjects are recorded when they listen to the unpleasant sound 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 unpleasant sound, and not). The HRV data are analyzed by using FFT. The experiment result shows that there exists relationship between VAS data and coefficient of covariance in HRV.
