interference with the message is known as noise
Models of communication The Shannon–Weaver model was designed to mirror the functioning of radio and telephone technology. Their initial model consisted of four primary parts: sender, message, channel, and receiver.The sender was the part of a telephone a person speaks into, the channel was the telephone itself, and the receiver was the part of the phone through which one can hear the person on the other end of the line. Shannon and Weaver also recognized that there may often be static or background sounds that interfere with the process of the other partner in a telephone conversation; they referred to this as noise. Certain types of background sounds can also indicate the absence of a signal.[1]
