Answer 1

Answer:

Hi here is your answer.

Explanation:

we have to decrease the amplitude of vibration of the sound.

Answer 2

Answer:

we have to decrease the amplitude of vibration of the sound.

Explanation:

Loudness of the sound L=10log

10

I

o

I

where I∝A

2

(A is the amplitude of vibration of sound)

Thus the loudness of sound varies directly as the square of the amplitude of vibration of the sound source.

Hence, the in order to reduce the loudness of sound, we have to decrease the amplitude of vibration of the sound.
