Detailed Solution

Ceilings and walls are curved so that the sound after reflection reaches the target audience.
Generally, concert halls are very big, and the sound from the speaker needs to travel to the audience in the hall. Since the sound becomes less audible with distance, the ceiling and walls are curved so that the sound gets reflected and reaches the target audience equally.
