What is loudness of sound? What factors does it depend on?

Answer:

Loudness of a sound depends on the amplitude of the vibration producing that sound. Greater is the amplitude of vibration, louder is the sound produced by it. The amplitude of the sound depends upon the force with which an object is made to vibrate. The loudness of a sound also depends on the quantity of air that is made to vibrate.
