Question

Why do auditoriums have curved roofs, curtains, carpets and false ceiling?

Answer 1

Answer:

In this question,

The auditoriums have curved roofs, curtains, carpets, and false ceiling because  

1) curved surface is used to spread sound in all the directions.

2) reverberation is due to repeated reflected sound from ceiling floors, walls so to reduce reverberation we should use absorbing material like curtain floor should be carpeted asbestos sheet should be used etc

Reverberation is the phenomenon of  persistence of audible sound after the source has stopped emitting sound
