Loudness is a physiological response of the ear to the intensity of sound which enables us to distinguish between a soft sound and a loud sound.

The loudness or softness of a sound is determined basically by its amplitude and loudness is proportional to the square of the amplitude of the vibrations.

Where greater the amplitude of vibrations, the louder the sound is produced.
