Explanation:
The ceilings of the concrete hall are made curved so that sound after reflection from the ceiling, reaches to all parts of the hall and the speech can be easily heard even by the person sitting at a considerable distance. The curved surface of ceiling reflects the sound of speaker towards the audience and hence prevents the spreading of sounds in various directions. Due to this, sound is distributed uniformly throughout the hall and even the person sitting at the back of the hall can listen the speech.
