The distance that the sound travels _____ affects attenuation.

Explanation:
Attenuation grows with distance because sound loses energy as it travels through a medium. The farther the sound travels, the more energy is absorbed or scattered, and the wave spreads over a larger area, so the resulting sound at the far point is weaker. In practice, intensity drops as distance increases, and higher frequencies tend to attenuate faster, making distance effects even more noticeable for those sounds. The idea that distance could decrease attenuation, have no effect, or occur randomly doesn’t fit how wave propagation works.
