An explanation of sound waves. The pitch of a sound is dictated by the frequency of the sound wave, while the loudness is dictated by the amplitude. When a drum is beaten, the air particles around the drum skin vibrate in the form of a compression wave

Ok so if it has a high amplitude the energy wave will be much bigger which would make a noise loud. Like if you were to hit a drum lightly the drum head wouldn't vibrate as much as if you were to hit it hard which would make the drum head vibrate a lot more
