What is the significance of noise in communication

Distractions can inhibit a person from offering his undivided attention and may keep him from fully grasping what you are trying to say. These disturbances guarantee that the receiver will either misinterpret your information or not understand it at all.

Sometimes the biggest impediment to clear communication is everyday environmental noise. This can include loud passersby, music think talking over a band at a concert , traffic or children playing. Even a simple phone ringing can distract a listener so that she cannot fully focus on a conversation.

Annoying whispering and classroom side bar conversations can interfere with the ability of the instructor and other students to focus on the material during a lecture. Other physical conditions that can hinder communication are physical illness, hearing impairments, being under the influence of drugs or alcohol, or being tired.

Semantic noise affects communication when people communicate from different playing fields. For example, a patient without knowledge of medical terminology may have no idea what the doctor is saying. In other words, they are working from different understandings, such as different vocabularies, primary languages or dialects. Noise can also occur when pedantic vocabulary or regional colloquilisms break down communication. Cultural noise occurs when cultural expectations, etiquette, attitudes, and values differ.

Just as with cultural noise, your task as a communicator dealing with psychological noise is to realize that people will interpret your message differently, depending on their own perspectives.

Try to reduce psychological noise by offering your communication very clearly and directly, using inclusive and unbiased language, and responding calmly and thoughtfully to questions and issues raised. Semantic noise deals with words and language. Is the language of the communication clear and easy to understand?

Is it free from professional jargon if the audience is at a low or mixed level of professional understanding? Are abstract concepts backed up by concrete examples? Is the language free from grammatical and technical errors? Are the sentences clear in their structure and easy to read or listen to? All of these language issues, however small, can derail focus from the content of your message.
