There are a lot of sounds that can be heard in nature, but there are a few sounds that strongly resonate with our hearts. There is a water dropping sound of the spring water, a waterfall sound, a stream flowing, a big rainy sound, and a wave sound. The characteristic of a sound generated by a specific place or space can be reminded of a sound image of that space, even if the sound is heard. Due to the characteristics of these sounds, the effect of white sound in various fields has been proven. In this paper, we have studied the similarity of wave sound in forest normal sound source. The similarity between the sounds of waves recognized by the hearing and the sounds of the normal forest can be confirmed through the characteristic of the periodicity of the waves in the sound of wind blowing from the forest top. In addition, the presence of similarity can be confirmed by comparing the psychoacoustic parameters, which are psychological aspects. In the future, we will explore the possibility of extracting more natural sound parameters, such as forest sounds, to obtain positive psychological or physical effects through various sounds.
