Hello, this is the definition of a boom arm -

"Attachment placed on a standard straight microphone stand which extends the reach of the stand to the side. Often used to place a microphone in front of a singer seated at a piano."

What does the word "boom" refer to in this context? Thank you.

    It means a rod (or something similar) attached to the vertical stand and projecting sideways. In the example of sound equipment it often projects sideways and upwards at an angle. The word may have come from sailing ships where the boom is a piece of wood projecting sideways from the mast.
