Boom
From Wikipedia, a free encyclopedia written in simple English for easy reading.
A boom is a low-pitched sound, often reverberant. The sound of thunder and the sound of an explosion are often called booms.
A boom is also a long bar. It is used in sailing and windsurfing to hold the sail, in beginner waterskiing for the skier to hold onto, and in recording and broadcasting (movies and television) to hold microphones.
