How is noise defined in the context of communication?

In the context of communication, noise is defined as anything that interferes with the effective delivery or reception of a message. Identifying noise as anything not related to the original message captures the broad spectrum of elements that can distort, distract, or obscure the intended communication. This includes irrelevant information, misunderstandings, or distractions that divert attention from the message itself, making it harder for the receiver to interpret what is being conveyed accurately.

The term "noise" encompasses both physical distractions, such as background sounds, and psychological barriers, such as biases or preconceived notions that may hinder comprehension. Thus, the focus on anything unrelated to the message highlights how numerous factors can impact communication effectiveness beyond merely external sounds or specific language issues.
