it is the cicadas
A male cicada has drum-like organs in its abdomen that produce a high-pitched drone similar to a loud vibrating noise.
The skin of the drum vibrates to produce sound.
by the ear drum vibrating
The head of the drum vibrates when struck. However, the whole drum reverberateswith that vibration. This is what gives the drum its tonal quality.
you bang it
the drum
Its a drum kit. Ambling means vibrating and a pad is a flat surface. Therefore an ambling pad is a drum kit.
The shell of the drum, or the place you pound to create noise, is stretched over a circular opening on both ends of the barrel of the drum. The tension is the factor that determines the noise produced.
Vibrating 'air' particles, through a transfer of energy; creating a sound wave which then reaches your ears and vibrates your ear drum. (doesn't have to be air, sound also travels through water ect)
It will make a noise. The pitch will depend on the type of drum.
When a drum is hit, the skin (head) starts to vibrate and transfer acoustic (kinetic) energy to the surrounding air. That energy is the "noise" of the drum.
