The size (amplitude) of the vibration determines the volume of the sound. The amplitude of the vibration carries the energy. A big vibration causes large sound waves that transmit a lot of energy. The resulting volume of sound is loud – for example, hitting a table with a ruler.
A small vibration causes small sound waves that transmit less energy. The resulting volume of sound is soft – for example, tapping a table with a ruler.
