Sound technicians prepare, maintain, and operate sound equipment for broadcasting companies, live events, and other recordings. As a sound technician, you must understand how to use audio, video, and recording equipment. For live events, sound technicians test acoustics and monitor echoes and other issues that may affect the performance. In a studio, sound technicians monitor a soundboard and adjust volume as necessary, then mix and manipulate sound to complete the feel of the scene. Sound technicians may also troubleshoot problems with sound equipment.
