MP Board · Class 9 · Science · SoundWhy are the ceilings of concert halls and cinema auditoriums usually curved?

The ceilings of concert halls and cinema auditoriums are purposely curved so that sound after reflection from the ceiling spreads uniformly to all parts of the hall. When sound waves originate from the stage and hit the curved surface, they reflect downwards towards the audience evenly across every corner, ensuring clear audibility for everyone sitting in the hall without creating dead zones.
