An analysis of the impressions felt by the subject's college students showed no significant difference when there was only one type of insect voice, but when the types were combined, the favorite score increased as the number increased.When analyzed by the four factors of calmness, gorgeousness, musicality, and depth, the score of gorgeousness and musicality increased significantly with the increase in the number.
The research group analyzes that the combination of insect voices diversified the rhythm and made them feel more favorable.
