Question

What will happen to loudness if the amplitude is tripled

Answer 1

Answer:

LOUDNESS ∝ AMPLITUDE²

so if amplitude is tripled the loudness will become nine times

Answer 2

EXPLANATION:

If the amplitude is tripled then loudness:

1. distance between listener and source is doubled.
2. amplitude of wave is tripled.
3. the surface area of the vibrating body gets increased.
4. the density of medium gets decreased.
5. the loudness of sound becomes 9 times greater.
