How is background noise categorized in the context of communication?

Background noise is categorized as a barrier in communication because it interferes with the clarity and effectiveness of the message being conveyed. When background noise is present, it can distort or muffle the sounds of the intended message, making it challenging for the listener to understand or respond appropriately. This disruption can lead to miscommunication or information being lost entirely, which is particularly critical in emergency situations where clear communication is vital. Understanding background noise as a barrier helps to underscore the importance of ensuring a quiet environment for effective communication, especially in high-stakes settings like 911 dispatch operations.
