This research measures the overall acoustic properties of spring and winter, and their difference is investigated from the perspective of environmental change. Forest in winter is very calm with occasional sound of birds and is devoid of insect sounds. The frequency components of winter forests are shifted towards the lower frequencies however, unique sounds caused by walking on snow compensates for this. Spring forests gives off a sense of gradually increasing vitality moving away from the calm of winter. Especially, as both the variety of bird species that cry and the frequency of those cries are increased significantly in the spring, the ratio of middle to high tone energies of the sound was about three times that of the 10% measured during winter. In all environments volume was louder than winter.
