Question

how does intensity of sound affected if the amplitude of sound is increased three times the original ( give proper explanation)​

Answer 1

Answer:

If the amplitude of the sound is made 3 times its initial value, then its loudness will become nine times its initial value. Loudness depends on the square of the amplitude of the wave. That is, Loudness∝(Amplitude)2. Thus, when amplitude of the wave is tripled, the loudness increases nine times.

Answer 2

Answer:

If the amplitude of the sound is made 3 times its initial value, then its loudness will become nine times its initial value. Loudness depends on the square of the amplitude of the wave. That is, Loudness∝(Amplitude)2. Thus, when amplitude of the wave is tripled, the loudness increases nine times.
