What is Noise?

According to Merriam-Webster Online,  noise is an unwanted signal or a disturbance (as static or a variation of voltage) in an electronic device or instrument (as radio or television).  In other words, noise is anything that detracts from the actual message that a communicator is trying to convey. Noise can take a variety of forms, from static in a radio broadcast to a conversation in the back of a classroom distracting students from paying attention to the teacher's message. This is undesirable because it can cause the actual information to be distorted. The only way to ensure that the message has been received with accuracy is to take any noise into account.

    This is fine, but what is the source of your information, Joe?

    I just wanted to tie this back in with feedback. If there was no feedback, there would be no way to detect if there was noise, and then we would not try to reduce the noise, and the message would never be received in the way it was intended.
