A "cough button" refers to a feature or device commonly found in broadcasting and recording studios, particularly in the radio or television industry. Also known as a "mute button" or "dump button," it is an instant and typically foot-operated switch that momentarily mutes or suppresses audio output. Its primary purpose is to quickly and effectively silence any unintended or inappropriate sounds that may occur during a live broadcast.
The term "cough button" originated from the practice of broadcasters using this feature to silence coughing sounds made by on-air personalities or guests during a live program. In addition to coughs, it can be used to silence sneezes, throat clearing, accidental noise, or any other undesired audio disturbances. By pressing the button, the audio signal is momentarily muted, creating a short pause, which conceals the unwanted sound from the final broadcast.
With the help of a cough button, broadcasters can ensure a smooth and uninterrupted flow of audio without disrupting the listening or viewing experience of their audience. It allows for swift control over unintentional noises, maintaining professionalism and preserving the quality of the program. This feature is especially critical in live broadcasts, where it is not possible to edit out such sounds during post-production.
The term "cough button" originates from the broadcasting industry. It refers to a button or switch that is used to momentarily mute the microphone, allowing the person speaking to cough or clear their throat discreetly without it being transmitted on air. The term logically stems from the action it is commonly used for, which is muting or blocking the sound of a cough.
