Physical noise is interference that is external to both speaker and listener; it hampers the physical transmission of the signal or message. Examples of physical noise are loud party at the neighbors while you’re trying to record, loud kids who don’t want to take their nap, irritating hum of your computer, air conditioner, or heater, etc. Semantic noise or semantic barrier is interference created when the speaker and listener have different meaning systems. Use of jargons, abstract ideas, using different language can be examples of semantic noise. Cultural noise or cultural barrier is a barrier to communication arising out of difference in cultural understanding and beliefs of sender and receiver. Psychological noise is mental interference in the speaker or listener. Three examples of psychological noise are wandering thoughts, preconceived ideas, and sarcasm.
