उत्तर
Loudness is the physiological response of the ear to the intensity of sound. The loudness of a sound depends on the amplitude of the vibration producing that sound. The greater the amplitude of the vibration, the louder the sound. The force that causes an object to vibrate determines the loudness of the sound. The loudness of a sound also depends on the amount of air that is vibrated.
