Distinguish between loudness and intensity of sound.

(N/A) Loudness is a measure of the response of the ear to the sound. It depends on the amplitude of the sound wave; higher amplitude results in greater loudness.
Intensity of sound is defined as the amount of sound energy passing per unit time through a unit area. It is a physical quantity that does not depend on the ear's response and is proportional to the square of the amplitude of the sound wave.
