In the basic model of communications, what is considered noise?

In the basic model of communications, noise is defined as anything that interferes with the transmission of a message from the sender to the receiver. This includes any kind of distortion or disruption that prevents the audience from receiving the message as it was intended.

For example, if someone is trying to communicate a critical safety instruction over a radio and there is static, background chatter, or any other form of interference, those disruptions hinder the clarity of the communication. This concept of noise can encompass various elements such as physical noise (like sounds in the environment), semantic noise (misunderstandings of language or terms), and even psychological noise (like emotional distractions impacting perception). Recognizing noise is important for effective communication, especially in high-stakes environments like firefighting, where clear and accurate messaging can be a matter of life and death.
