Question

Ceilings of concert halls are curved to uniformly spread sound in all directions after reflecting from the walls.

Answer 2

$\huge \mathsf{\orange {\underline {\purple {\underline { Required \ answer \ ♡ \ :- }}}}}$

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.
