boom operator

A boom operator (or First Assistant Sound) is a core role in the sound department of a film production, who works with the production sound mixer and utility sound technician. The principal responsibility of the boom operator is microphone placement, usually using a boom pole (or "fishpole") with a microphone attached to the end (called a boom mic), their aim being to hold the microphone as close to the actors or action as possible without allowing the microphone or boom pole to enter the camera's frame.
