Question

If we reduce the amplitude of the sound wave to one-third then the loudness becomes​
options
1 .9 times
2. 3 times
3. 1/9 times
4. 1/3 times

Answer 1

Answer:

I/3 , The loudness of sound is directly proportional to amplitude of sound wave.

loudness ∝ amplitude

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.

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.
