Which property of sound waves decreases as the square of the distance from the source increases?

intensity is the answer

Intensity

Explanation:

The intensity of a sound wave is equal to the ratio between to the power emitted by the source divided by the area of the spherical surface through which the wave propagates:

where

P is the power

is the area of the spherical surface

r is the distance from the source

As we see from the formula, the intensity is inversely proportional to the square of the distance from the source:

so, intensity is the correct answer.
