Question

state the effect on the loudness of a sound when the amplitude of vibration body increase

Answer 1

they are directly related so one increases other also increases

Answer 2

amplitide of vibration is directly proportional to the loudness of sound .


so greateramplitude produces louder sound.Loudness of a sound is directly related to amplitude ,in fact it is the square ofamplitude .



for simple eg


in our ear eardrum amplifly the sound so due to this we hear clearly and loudly.
