MP Board · Class 9 · Science · SoundWhy are the ceilings of concert halls and cinema halls curved? Explain.

The ceilings of concert halls and conference rooms are made curved so that sound after multiple reflections from the curved surface spreads uniformly and reaches all corners of the hall. The curvature acts like a spherical reflector, ensuring that the sound energy is directed toward the audience seated even in distant rows, making speech and music clearly audible without dead zones.
