Answer 1

Hint: Curtain behaves as a sound absorber which absorbs the unwanted sound and prevents echo thus, we do hear more clearly in a room with a curtain than in an empty room.

Complete step by step answer:
 It is asked in the question why we hear more clearly in a room with curtains than in a room without curtains, we know that curtains act as a sound absorber when it is present in any room.
When we speak in a room having no curtain then in this case our sound reflects again and again with the walls and this forms the echo in our sound. Many a time the sound waves interleaf and won't sound pleasant. Basically, when we speak in an empty room the sound gets reflected again and again and produce echo but when we speak in a room having curtain then the quality of the sound drastically charges, here the curtains are behaving as a sound absorber and all the sound waves are absorbed by the curtains and it will not overlap and reflect again and again by the walls of the room this will reduce the echo effect.
We can say that curtain absorbs all the unwanted sound, as a result, the sound does not reflect again and again and this improves the quality of the sound but in the first case when we speak in an empty room the sound wave reflects again and again by the walls of the room and produces an echo. This is the reason why singers use more and more forms in their study just to prevent the echo effect and absorb the unwanted sounds which improve the quality of the music.

Note:
We can use any form like things to absorb the unwanted sounds generally in our home we have the bed, sofa, curtain and many more things present which absorb unwanted sound and prevent sound to reflect from the walls and produce an echo.
