Solution

The loudness of sound depends on the area of the vibrating body. Greater the area of the vibrating body, the louder the sound produced.

Consider two drums, one small and one big, and beat both of them to produce vibrations in them. You will notice that the sound produced from the big drum with a larger surface area is louder than that produced from the small one with a smaller surface area.
