Question

if the amplitude of sound is √2 times in initial amplitube then

Answer 1

Answer:

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.
