Shannon and Weaver - 1949
The academic field of mass communication were heavily influenced by the engineering/mathematical model of communication.
Communication
was conceived as a linear model of transmission of a message from a source to a receiver
via a signal producing transmitter. Shannon
and Weaver’s mathematical theory of communication is widely accepted as one of
the main seeds of communication studies.
During
II world war the main channels of communication were telephone cable and the
radio wave.By
this approach we understand how to send a maximum amount of information along a
given channel to carry information.
Features of Shannon and Weavers model
(i)
It presents
communication as linear process
(ii)
It is a
simple model.
(iii)
The message
is decide by the source transmitted into a signal(encode) which is sent through a
channel to the receiver
for example: In
conversation the mouth is transmitter, the signal is the sound wave which pass
through the channel of the air and ear is receiver
Three level of problems/Noises
Technical problem- The simple to understand
Semantic problem-easy to identify but hard to solve
Effective problem- as communication as manipulation or propaganda
The three levels are interrelated and interdependent.
The source is seen as the decision maker and he decides which message to sent.
This selected message is then changed by the transmitter in to a signal which is sent through a channel to the receiver.
In this model introduced the term noise. This noises may be a blinding fog blurred rain, soaked pages of a newspaper.
I'm studying for a Project Management exam and am trying to grasp where the idea of receiver responsibility comes into play. It says the receiver must ensure the message is received in its entirety, understood, and acknowledged to the sender. Now I get that in today's modern world of instant send and receive we can do this fairly easily. But I don't see where any of this comes out of the model or how Shannon-Weaver would have thought up the concept to begin with. Is there some other communication theory that I am missing that explains this more thoroughly? Thanks
