Answer 2

loudness depends on the following factors:-
1) loudness is proportional to the square of the amplitude - when a body vibrates with a greater amplitude, it sends forth a great amount of energy and hence the energy received by the eardrum is large so the sound appears louder.
2)loudness depends on the surface area of the vibrating body - a larger vibrating area sends forth a greater amount of energy.
