Which of the following choices correctly describes the behavior of sound waves when the compressions from one wave overlaps with the rarefaction of another?
(A) A compression interferes constructively with the region of rarefaction, so that the waves reinforce each other. The sound becomes louder under constructive interference.
(B) As the two waves overlap they refract as well, changing speed and direction. The sound does not become louder or quieter when refracting.
(C) A compression interferes destructively with the region of rarefaction, so the waves cancel each other out. The sound becomes quieter under destructive interference.
(D) A compression interferes destructively with the region of rarefaction, so the waves cancel each other out. The sound does not become louder or quieter under destructive interference.
