Among them, forest sounds are applied to psychological characteristics such as depression and anxiety, and many examples using psychoacoustic are also being announced. Psychoacoustic sounds are not perceived as a certain form in every person who listens to the same sound, but differently depending on the environment and experience of the person and the psychological state of the situation. There are differences in the forests depending on the environment of each season and the shape of the forest, making it difficult to draw accurate characteristics. Therefore, it is necessary to extract the space that can represent the environment of the forest and understand the acoustic characteristics. In this paper, the purpose of this paper is to analyze forest sound in spring using psychoacoustic parameters. In order to investigate the psychological effects of the forest sound in spring, we tried to analyze and analyze the characteristics of various sounds in the forest.
