This paper analyzes the results of a subject experiment designed to evaluate anxiety about simple harmonic vibrations. We examined the correlation between biological reactions and anxiety levels when subjects experienced simple harmonic vibrations by measuring questionnaires and biological reactions and analyzing the correlation between them. The results of a subject experiment using EEG and ECG showed no correlation between EEG indices and questionnaires, but there was a correlation between ECG indices and questionnaires. We found that there is a correlation between ECG indices and anxiety levels.
