Multiple Choice

The further sound travels, the attenuation becomes ______ and the beam becomes ______.

Explanation:
As sound travels, it loses energy through absorption, scattering, and geometric spreading. This loss accumulates with distance, so attenuation becomes greater the farther the sound goes. Because the wave is losing energy, its amplitude and intensity drop, making the beam weaker. Choosing the other possibilities would imply that attenuation decreases with distance or that the beam becomes stronger, which doesn’t align with how sound propagation works in media.
