ind why are sound absorbing​

Answer 1

Explanation:

For a classroom with an appropriate reverberation time, it is necessary for the room to be between 200 and 20,000 cubic meters.

In a classroom, it is important to have uniform sound distribution so that the sound must be able to be heard equally well everywhere. An appropriate sound level of 60-65 dB ensures an appropriate sound level. A variation of max. 15 dB anywhere in the room is an appropriate requirement.

It is better to prevent echoes by installing a little sound-absorbing material on the wall.

Spherical, cuboid or cylinder shapes for the rooms should be avoided. Also, the listening rooms and projector or TV rooms in schools should be built up symmetrically around a vertical plane bisecting the central space.
