Dead air意思

"Dead air" is a term used in broadcasting to refer to the period when there is no audio output during a live broadcast. It typically refers to silence that is unplanned and unscheduled, and it can be caused by various factors such as equipment failure, human error, or technical difficulties.

In the context of radio broadcasting, dead air can be particularly problematic because it can lead to a loss of listener engagement and even a loss of listeners. Therefore, broadcasters take measures to prevent dead air, such as having backup systems in place and ensuring that all equipment is functioning properly before going on the air.

The term "dead air" can also be used metaphorically to refer to any situation where there is a lack of communication or activity, especially in situations where communication or activity is expected or required.
