 Noise source: Noise is the enemy of information. ForShannon and Weaver, noise is more than an irritatingsound or static on the line. It is anything added tothe signal that’s not intended by the source. Anyadditional signal that interferes with the receptionof information is noise. For example, noise can besmudged newsprint, a visual movement that distractsthe listener, a background noise in the immediatesurroundings, a noisy channel (a cracklingmicrophone), or the organization and semantic aspectsof the message (syntactical and semantically noise).
