Question:

What happens to the loudness of sound as one moves away from it?

Answer:

B. Fade Away

As distance from the sound source increases, the area covered by the sound waves increases. The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less. This explains why even loud sounds fade away as you move farther from the source.
