Outline of Final Research Achievements

This study is an experimental research to investigate the influence of fluctuating low frequency sound on the human body by psychophysiological response measurement. In addition, we examined the influences of the low frequency sound above the sensation threshold level based on the efficiency of mental task. The fluctuating low frequency sound used by this research fluctuated the fluctuation cycle of the carrier wave and the sound pressure level periodically by the amplitude modulation. The fluctuating low frequency sound based on the whole-body exposure activates activities of the sympathetic nerve. In other words, this result suggest that the stress reaction is induced by the fluctuating low frequency sound. The subjects cannot concentrate on the mental task during the fluctuating low frequency sound exposure. Especially, the correct answer ratio of thinking task performance was found to decrease when the fluctuating low frequency sound above the threshold level were present.
