| Abstract(in English) | It has been widely accepted that the physical stimulation, like illumination, music and environmental variables having a 1/f fluctuation power spectrum, relaxes a person. There should, however, exist a number of the stimulation waveforms that can produce 1/f power spectral characteristics, and thus the parameters of the waveform in the time domain causing comfortable biostimulation remain unknown. As a first step in elucidating what kinds of biostimulation waveforms relax a person, this paper theoretically derives CRD (crossing rate distribution: times per one second where the amplitude crosses a level in the positive direction) for a Gaussian fluctuation waveform with a 1/f^α power spectrum. Flame fluctuation of candles causing a sedative effect is statistically measured. The findings obtained here show that the flame with spectral characteristics similar to 1/f fluctuation has the peak crossing rate of 0.3-0.4 Hz, fluctuating with the rhythm close to person's breathing. |
