Channel noise degrades the radio signal, so the receiver may mishear or fail to decode what was said. To avoid miscommunication, the sender often has to repeat and the listener may ask for clarification, which slows the exchange and leads to delayed responses. Visual misinterpretation isn’t related to voice radio, and noise typically increases the need to confirm or report rather than reduce it. Redundancy can help overcome noise, but the issue caused by the noise itself is the delays from having to repeat or clarify.
