Answer:

a. one-fourth its original value.

Explanation:

Sound is threated as a spherical wave. The intensity of the sound is inversely proportional to the area of ​​the wavefront ([tex]4\pi r^2[/tex]). Therefore, it is inversely proportional to the square of the distance (r) to the sound source. So, if you double your distance, the intensity of the sound reduces to one-fourth its original value.
