Question

Why do we hear more clearly in a room with curtains than in a room without curtains?
(A).Sound is absorbed by the curtains
(B).Less reverberation
(C).A and B
(D).None

Answer 1

Hint: As we know that curtains acted as a good absorbent of the sound.

Complete answer: We hear more clearly in a room with curtains than in a room without curtains because curtains act as a good sound absorbent.
So, they absorb the sound produced in the room and consequently, it prevents the unwanted echo of the sound due to the refraction.
Otherwise, the overlapping of the sounds would be most unpleasant as we won't be able to hear clearly.
We hear more clearly in a room that we curtained than in a room that is without curtains because the curtains are the bad reflectors of the sound.
They absorb most of the sound falling on them, and consequently don’t produce echoes.
In a curtain room, there is a greater reflection of the sound and the echoes are formed. These echoes cause an obstacle to hearing.
So, the sound is absorbed by the curtains.

So, the option (A) is correct.

Note:
We hear the sound more clearly in a room with curtains than in an empty room, because in the empty room there are no absorbents of sound.
Consequently, the sound will reflect and most of the time it leads to the echoing of the sound whereas in a room filled with curtains the sound will be absorbed by them and won’t let the sound to reflect or to cause echo.
Accordingly, we hear a better clear sound in a room with curtains than in an empty room.
