The amplitude of a sound wave determines the amount of energy it carries.
The amount of sound energy passing each second through unit area is called the intensity of sound.
Does this mean that Amplitude and Intensity of the sound are same?????
 

Dear Student,

No, amplitude and intensity of sound are not same. Amplitude is directly related to the acoustic energy or intensity of a sound. Both amplitude and intensity are related to sound's power. Intensity is directly proportional to the square of amplitude.
Intensity α Amplitude²
