Communication noise

In any communication model, noise is interference with the decoding message 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 speaker at a party, or the noise from a construction site to a classroom making it difficult to hear the professor.

• Physiological-Impairment Noise: Physically 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 meaning 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: Mistake 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 misunderstanding, 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.
