This paper discusses the effects of listening to ultrasonic sound with 1 / f fluctuation in the autonomic nervous system by conducting two experiments. The first is an experiment that increased the number of subjects from the previous study. The second is an experiment to confirm what kind of 1 / f fluctuation can predominate parasympathetic activity. As a result, in the first experiment, it was confirmed that subjects with active parasympathetic activity existed when 1 / f fluctuation sound source was given. In the second experiment, it was confirmed that subjects with more active parasympathetic nervous activity existed as the degree of modulation increased between 10% and 30%. From these results, this study discovered unique effect of 1 / f fluctuation for the autonomic nervous system.
