Answer 1

The ceiling of concert halls are curved because people seated at the back rows of the hall may not hear the sound from the speaker clearly. When the ceiling is curved or concave, it helps in reflecting sound waves making it travel to farther distances.

Answer 2

Answer:

Concert halls are very big, so the sound might not reach every corner of the hall. So, ceilings of concert halls are made curved so that after reflecting, it reaches all parts of the hall. A curved ceiling acts as a large concave soundboard and reflects sound down onto the audience sitting in the hall.
