What is noise?
In simple terms, noise is unwanted sound. Sound is a form of energy which is emitted by a
vibrating body and on reaching the ear causes the sensation of hearing through nerves.
Sounds produced by all vibrating bodies are not audible. The frequency limits of audibility
are from 20 HZ to 20,000 HZ
