Sound engineers (also called audio technicians), make things sound good. As a soundperson, you take what comes over microphones, amplifiers and other sources and adjust the levels of various tones (bass, drums, voice, guitar, for example) to make it all work together. You also listen for things most people never even think about. No one wants to hear papers rustling or throats clearing, so for every performance, a sound engineer makes sure everyone can hear what's going on and that the sound is as free of disturbances as possible. Sound engineers make from $25,000 to $57,000.
