Abstract
It has been reported to be effective healing using the 1/f fluctuation, that this is observed in the healing environment is known. In this study,it is an object of the present invention generation of pseudo-natural fluctuating signals. Analyzes the sounds waves sound pressure change of natural sounds, and confirmed the importance of the phase shift. This time, Result of calculating the mapping sound waves sound pressure, it was possible to observe the characteristics of the two-layer structure and mapping of the loop.We propose an algorithm that generates an fluctuating signal by using the formula 4 using the two features.
