The amplitude of the sound wave depends on the force with which an object is made to vibrate. Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. The loudness of sound refers to the intensity of sound waves. It depends on the amplitude of vibrations.
