What determines sound amplitude?

Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves . Greater amplitude waves have more energy and greater intensity, so they sound louder. As sound waves travel farther from their source, the more spread out their energy becomes.

amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position . It is equal to one-half the length of the vibration path.

Amplitude—maximum displacement from the equilibrium position of an object oscillating around such equilibrium position . Frequency—number of events per unit of time. Period—time it takes to complete one oscillation.

A sound wave’s amplitude relates to changes in pressure. The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases .27 Oca 2022
