Detailed Solution

The above statement is true.
The ceiling of concert and cinema halls is curved so that the sound can reach all corners properly. The curved surface of the ceiling acts as a reflector of sound; the sound, after reflection from the curved surface, reaches all corners of the hall uniformly and contributes to providing an immersive experience to the people sitting in the hall.
