Wind-induceed foliage sound is generated when wind causes grass and leaves to rub against each other. Dead leaves lose moisture and reduce mass, causing the leaves to become stiff. The frequency of wind-induceed sound of dead leaves is higher than that of green leaves. This paper analyzes the results of a sound experiment using four types of leaves, which are readily available. Leaf mass and rigidity were compared. After collection, mass decreased daily, and over a 10-day period the leaves were about half of the original. However, rigidity varies widely between the different species of leaves and is 1.5 times the maximum. An analysis model, using sandpaper attached to cardboard was prepared and rubbed together to generate sound. The results show that sound frequency of actual leaves and the sandpaper model were relatively similar.
