Noise and Interference in Various Types of Communication

In communication studies and information theory, noise  refers to anything that interferes with the communication process between a speaker and an audience. Its also called interference. Noise can be external (a physical sound) or internal (a mental disturbance), and it can disrupt the communication process at any point. Another way to think of noise, notes Alan Jay Zaremba, author of Crisis Communication: Theory and Practice is as a factor that reduces the chances of successful communication but does not guarantee failure. Examples and Observations Craig E. Carroll, author of The Handbook of Communication and Corporate Reputation likens noise to second-hand smoke having negative impacts on people without anyones consent. External noises are sights, sounds and other stimuli that draw peoples attention away from the message. For instance, a pop-up advertisement may draw your attention away from a web page or blog. Likewise, static or service interruptions can play havoc in cell phone conversations, the sound of a fire engine may distract you from a professors lecture or the smell of donuts may interfere with your train of thought during a conversation with a friend.(From Communicate! by Kathleen Verderber, Rudolph Verderber, and Deanna Sellnows) Kinds of Noise There are four kinds of noise. Physiological noise is a distraction caused by hunger, fatigue, headaches, medication and other factors that affect how we feel and think. Physical noise is interference in our environments, such as noises made by others, overly dim or bright lights, spam and pop-up ads, extreme temperatures, and crowded conditions. Psychological noise refers to qualities in us that affect how we communicate and interpret others. For instance, if you are preoccupied with a problem, you may be inattentive at a team meeting. Likewise, prejudice and defensive feelings can interfere with communication. Finally, semantic noise exists when words themselves are not mutually understood. Authors sometimes create semantic  noise by using jargon  or unnecessarily technical language.(From Interpersonal Communication: Everyday Encounters by Julia T. Wood) Noise in Rhetorical Communication Noise...refers to any element that interferes  with the generation of the intended meaning in the mind of the receiver...Noise may arise in the source, in the channel; or in the receiver. This factor of  noise  is not an essential part of the rhetorical  communication process. The  communication process  is always hampered to some degree if noise is present. Unfortunately, noise is almost always present. As a cause of failure in rhetorical communication, noise in the receiver is second only to noise in the source. Receivers of rhetorical communication are people, and no two people are exactly alike. Consequently, it is impossible for the source to determine the exact effect that a message will have upon a given receiver...The noise within the receiver—the psychology of the receiver—will determine to a great extent what the receiver will perceive.(From An Introduction to Rhetorical Communication: A Western Rhetorical Perspective by James C. McCroskey) Noise in Intercultural Communication For effective communication in an intercultural interaction, participants must rely on a common language, which usually means that one or more individuals will not be using their native tongue. Native fluency in a second language is difficult, especially when nonverbal behaviors are considered. People who use another language will often have an accent or might misuse a word or phrase, which can adversely affect the receivers understanding of the message. This type of distraction referred to as semantic noise, also encompasses jargon, slang  and even specialized professional terminology.(From Understanding Intercultural Communication: The Working Principles by Edwin R McDaniel, et al) Sources Verderber, Kathleen; Verderber, Rudolph; Sellnows, Deanna.
