The ceiling of concert halls is curved because people seated at the back rows of the hall may not clearly hear the speaker’s sound. When the ceiling is curved or concave, it reflects sound waves making it travel farther distances.
Some facts about sound waves
- Sound travels in mechanical waves. A mechanical wave is a disturbance that moves and transports energy from one place to another through a medium.
- Sound travels in all directions; the amount of noise you hear depends on several different factors.
- Sound waves are travelling vibrations of particles in media such as air, water or metal.
- Sound cannot travel through a vacuum. A vacuum is an area without any air, like space.
