Explanation:

Noise is an interference in the channel of communication.

Non-technically, communication noise includes physical noise, psychological noise, and semantic noise. These types of noises affects the communication between humans and can cause misunderstanding.

Technically, Noise can be defined as an unwanted electrical signal that influences the meaningful signal (message).  Noise is random disturbance which can arise from natural phenomenon as well as from other electrical devices nearby.

We have a whole set of frequency spectrum. The range of frequencies for humans is 20 hz to 20 khz. We can use filtration to filter out a range of frequencies and to eliminate noise.
