Claude Shannon and Warren Weaver’s Communication Model

American applied mathematician Claude Shannon and Engineer Warren Weaver developed a mathematical theory of communication in 1949 while working at Bell Telephone Laboratories in the United States. Later this model has become well- known as “information theory”. Shannon and Weaver’s model is widely accepted as the route from which Communication Studies has grown.

Shannon and Weaver model consists of the following the elements:

(i) An information source, which produces a message

(ii) A transmitter, who encodes the message into signals

(iii) A channel, to which signals are adapted for transmission

(iv) A receiver, who ‘decodes’ (reconstructs) the message from the signal

(v) A destination, where the message arrives.

In the model they indicated a sixth element, “noise” as a dysfunctional factor. The model is shown below:

Advantages of Shannon and Weaver’s model: The strengths of Shannon and Weaver’s model are:

  • simplicity
  • generality, and
  • quantifiably

Such advantages mode this mode/ attractive to several academic disciplines.

As Shannon was an engineer, this model was first made to improve technical communication, mainly for telephonic communication. It was made to maximize telephone capacity with minimum noise. Later, Weaver applied it for all kind of communications to develop effective communication and the model became famous as Shannon Weaver model.
