Noise means any unwanted sound. In both analog and digital electronics, noise is an unwanted perturbation to a wanted signal; it is called noise as a generalisation of the audible noise heard when listening to a weak radio transmission. Signal noise is heard as acoustic noise if played through a loudspeaker; it manifests as ‘snow’ on a television or video image. Noise can block, distort, change or interfere with the meaning of a message in human, animal and electronic communication. — Wikipedia

Introduction


Communication Noise In any communication model, noise is interference with the decoding of messages sent over a channel by an encoder. There are many examples of noise:

Environmental Noise Noise that physically disrupts communication, such as standing next to loud speakers at a party, or the noise from a construction site next to a classroom making it difficult to hear the professor.

Physiological-Impairment Noise Physical maladies that prevent effective communication, such as actual deafness or blindness preventing messages from being received as they were intended.

Semantic Noise Different interpretations of the meanings of certain words. For example, the word “weed” can be interpreted as an undesirable plant in your yard, or as a euphemism for marijuana.

Syntactical Noise Mistakes in grammar can disrupt communication, such as abrupt changes in verb tense during a sentence.

Organizational Noise Poorly structured communication can prevent the receiver from accurate interpretation. For example, unclear and badly stated directions can make the receiver even more lost.

Cultural Noise Stereotypical assumptions can cause misunderstandings, such as unintentionally offending a non-Christian person by wishing them a “Merry Christmas”.

Psychological Noise Certain attitudes can also make communication difficult. For instance, great anger or sadness may cause someone to lose focus on the present moment. Disorders such as Autism may also severely hamper effective communication. — Wikipedia
