The maximum extent of a vibration or oscillation, as measured from the equilibrium position, is its amplitude.
Now we will analyze the amplitude of sound waves with the help diagram.
The number of molecules that are moved by a vibration determines the sound's amplitude. the volume or force of the sound.
The amplitude of the sound wave in is bigger because there are more molecules in it than there are in the sound wave in .So it is evident from the description above that if there are fewer displaced molecules, the amplitude will be smaller, and if there are more molecules vibrating, the amplitude will be larger.
Factors affecting the amplitude of sound waves
The amount of energy needed by the source to produce the sound. A wave's energy content is inversely proportional to its amplitude. A wave with a high amplitude carries a lot of energy, while one with a low amplitude carries less energy.
The frequency response of the surroundings and the source.
