Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
[4] [5] Later, Wilbur Schramm introduced a model that identified multiple variables in communication which includes the transmitter, encoding, media, decoding, and receiver. [ 6 ] In Berlo's SMCR model, the sender is one who sends the message, the receiver receives the message, which is transmitted through the channel where disturbances might ...
But their model is intended as a general model that can be applied to any form of communication. [ 9 ] [ 10 ] [ 11 ] For a regular face-to-face conversation, the person talking is the source, the mouth is the transmitter, the air is the channel transmitting the sound waves, the listener is the destination, and the ear is the receiver.

[16] [8] [17] For example, James Watson and Anne Hill see Lasswell's model as a mere questioning device and not as a full model of communication. [10]
