Question

If amplitude of a sound is reduced by ⅓ then what happened to its loudness?​

Answer 1

Answer:

I/3 , The loudness of sound is directly proportional to amplitude of sound wave. Hence on reducing amplitude the loudness also decreases. Explanation: If the amplitude of the sound is made 3 times its initial value, then its loudness will become nine times its initial value.

Answer 2

Answer:

I/3 , The loudness of sound is directly proportional to amplitude of sound wave. Hence on reducing amplitude the loudness also decreases. Explanation: If the amplitude of the sound is made 3 times its initial value, then its loudness will become nine times its initial value.
