The "decoding" of a message is how an audience member is able to understand, and interpret the message. It is a process of interpretation and translation of coded information into a comprehensible form. The audience is trying to reconstruct the idea by giving meanings to symbols and by interpreting the message as a whole. Effective communication is accomplished only when the message is received and understood in the intended way. However, it is still possible for the message recipient to understand a message in a completely different way from what the encoder was trying to convey. This is when "distortions" or "misunderstanding" arise from "lack of equivalence" between the two sides in communicative exchange.
