Boom

The term ‘boom’, in audio and sound, can refer to a few things.

A) In the realm of sound recording, a boom is a long, usually collapsible, pole that allows a production sound recordist to record film dialogue without getting in the camera shot. Ideally it is lightweight as the boom operator is often holding it for extended periods of time at extreme angles that become tough on the forearms. Boom poles can range in price from $100 for entry-level poles to over $1000 for professional gear. 

B) Sometimes, the term boom is used as the term ‘boom-mic’ to describe a shotgun microphone. This is improper usage of the term, as the boom is the device used to hold a shotgun microphone, but the terms are sometimes used interchangeably.

C) Boom is also a descriptive word used in the post-production world of sound. A boom sound is typically a sound effect or other sound containing heavy low-end frequency content and a heavy or fast attack. A sound like the one heard here can be considered a boom or having a ‘boomy’ sound quality.
