Shannon and Weaver Model of Communication

American mathematician Claude Elwood Shannon and scientist Warren Weaver introduced the Shannon and Weaver communication model in 1949 by the article of THE MATHEMATICAL THEORY OF COMMUNICATION. Initially, they proposed this mathematical model to describe the signal transmitting system and enhance telephone communication by minimizing noise. Now it is applied in every field of information and communication broadly. However, they did not present the “Feedback”; hence, the Shannon and Weaver model is an example of a linear communication model. Originally, the Shannon-Weaver model excludes feedback; therefore, it is a linear communication model.

Later, Norbert Weiner included feedback to the model in countering the criticism of the one-way communication approach. Shannon and Weaver’s communication model is termed the “mother of all communication models” for its extreme popularity. Shannon and Weaver’s Communication Model is also called the mathematical theory of communication, Shannon theory, and information theory in the engineering disciplines.

Feedback in Shannon Weaver Model

In 1950, Norbert Wiener added the “Feedback” in Shannon and Model. He presented the feedback system in the book (The Human Use of Human Beings) originally published in 1950. Norbert Wiener is also the founder of cybernetics theory that explains the feedback system. Shannon and Weaver have not published the modified model including feedback. Hence, the original model of Shannon and Weaver is linear as they did not mention feedback.

Shannon-Weaver Model Examples of Situation
Shannon and Weaver Model Example: 1

For example, Jon calls his friend (Jony) through the smartphone to meet on Monday. Children are screaming around Jony; therefore, he cannot hear what Jon says.

Jon is a source of information that generates the message. The information source is Jon, also the sender of the message. Additionally, the smartphone is a channel that converts the message(voice) into the sound wave signal to transmit from the sender(Jon) to the receiver(Jony). Children screaming sound is the noise that bars the communication process. Jony decodes the voice into a message, so he is the receiver and destination of the message.

Shannon and Weaver Model Example: 2

The lecturer conducts online classes through the Zoom virtual meeting platform. However, a student cannot hear the lecture properly due to the raining sound, also known as the physical noise in communication.

The lecturer is the source of information. Zoom meeting is the channel of communication that transmits message into a signal to convey to students. The students receive the message via their smartphones or computers. So, they are the receiver of the message. Finally, the raining sound is the noise that distracts the student from hearing the lecture correctly.

Shannon – Weaver Model Example: 1

Jon is listening to morning news via radio. The news presenter broadcast news regarding today’s weather forecast. However, he cannot hear the report for the radio frequency interference (RFI). RFI is created from an internal wireless system.

The news presenter is the information source, radio is the channel, Jon is the receiver, and radio frequency interference is also known as electrical noise.

These are the 3 example situation of the Shannon-Weaver model of communication.

Shannon and Weaver Model of Communication Explanation

The Shannon and Weaver communication model includes the six elements: Information Source, Transmitter, Channel, Receiver, Destination, and Noise Source. However, Shannon and Weaver did not mention “Feedback” in 1949; hence, it is a linear communication model. Many researchers and practitioners criticize this model due to not adding the “Feedback.” Therefore, later, Norbert Weiner included “Feedback” to describe the transactional communication process.

Many communication models have been postulated based on this model- for example Osgood-Schramm transactional model.

Shannon and Weaver Model of Communication Elements

The Six Elements of Shannon and Weaver Model of Communication are:

  1. Information Source.
  2. Transmitter.
  3. Channel.
  4. Receiver.
  5. Destination.
  6. Noise Source.

 1. Information Source

Information source refers to the sender of the communication process that conveys the message to the receiver. It also indicates the person who generates the information and initiates the communication process.

For example, the lecturer gives a motivational speech for new students in the orientation program using a dynamic microphone. In the meantime, an airplane passes over the program. So, students can not hear the lecturer’s speech for a while.

2. Transmitter

The transmitter refers to the message converter that changes the message into a signal to transfer through the communication channel. It is also called the encoding process. The messages are spoken words, written messages, pictures, music, and nonverbal communication cues.

For example, the lecturer’s speech transmits through the dynamic microphone. The microphone converts the spoken word into the signal to transfer via electrical current on the wire.

3. Channel

Channel is the medium that conveys the message from senders to receivers. The communicators utilize distinguished channels based on the communication process such as human senses, radio, television, newspaper, electronic tools, social media, and so more.

For example, the wire is the channel that conveys messages from the lecturer to students.

4. Receiver

Receivers are the people who convert the signal into a meaningful message. They are responsible for decoding the message. So, receiver is decoder of the communication process.

For example, students are the receivers who process the signal and sound into a meaningful message.

5. Destination

Destination indicates both senders and receivers of the communication process who encode and decode the message.

According to Shannon and Weaver’s Model of Communication, “when I talk to you, my brain is the information source, yours the destination; my vocal system is the transmitter, and your ear and the associated eighth nerve is the receiver.”

6. Noise

Noise is the unwanted sound of the communication process that disrupts the effective communication process. Communicators certainly found noises in every type of communication process, including verbal, nonverbal, written, visual, face-to-face, mediated, and group communication. The most common types of noise in communication are physical, physiological, psychological, semantic, electrical, syntactical, cultural noise, and so more.

For example, the airplane sound is considered the physical noise in communication that distracts the students from hearing the speech.

Conclusion

In short, the Six Elements of the Shannon and Weaver Model of Communication are Information Source, Transmitter, Channel, Receiver, Destination, and Noise Source. Eventually, Norbert Weiner included the seventh element(Feedback) to make it a transactional model of communication. Shannon and Weaver Model was introduced in 1949 and it is certainly a linear model of communication.

Established Year of the Shannon-Weaver Model?

The Shannon and Weaver model was introduced in 1949. However, there is controversy regarding the establishment year of the Shannon and Weaver model. Claude Shannon published the article(A Mathematical Theory of Communication) in Bell System Technical Journal in 1948; It was known as the Shannon theory. Warren Weaver republished the previous article in 1949, adding more information and discussing the model’s implication on the effective communication process. They also renamed it The Mathematical Theory of Communication while republishing it in a book. Therefore, it is known as the Shannon-Weaver model of communication.

Warren Weaver did not contribute to the article (A Mathematical Theory of Communication) published in 1948 by Claude Elwood Shannon. So, Weaver’s name cannot be included in the model published in 1948. He became co-author of the same article in 1949 also renamed it “The Mathematical Theory of Communication” while reprinting in the book. The Mathematical Theory of Communication is called Claude Shannon and Warren Weaver model of communication. So, it is rational to say that the Shannon and Weaver model was introduced in 1949, not 1948.
