Four friends, a, b, c and d are standing varying distances away from a speaker which is producing sound waves. which person will most likely hear the loudest sound?

a) a

b) b

c) c

d)d

A ( a )

Step-by-step explanation:

The closer you are to a sound source ( speaker ) the louder the sound is but the farther you are the less likely you are to hear a sound this is because sound travels through the air and losses some of its content when it travels.

from the question it is noticed that the four friends stood at Varying distances starting from Friend A down to Friend D, and from the question description Friend A is the closest to the speaker and friend D is farthest from the speaker which is the sound source.

Friend D will most likely hear the least sound as long as he is the farthest frm the sound source.
