why are the walls of cinema halls carpeted with some rough surface?
Answers
a) Cinema halls and audutoriums are carpeted and the walls are made of rought material. It is because these materials absorb the sound and do not allow them from going out of as, some times the sound can be a trouble to the people. ... If the classroom would be empty the sound would echo because of the even surface in it.
because it allows only direct sound to reach the audience .they are even made up of sound proof wall with the concept of two walls and a gap between them so that the sound does not go out and disturb the other people and in another hand to much echo and reverberation makes the sound muddled and we cannot hear anything (dialogues )etc .clearly.
