Microphone System

This design group set its sights on designing an automated microphone boom system for the B. J. Haan auditorium on the campus of Dordt College. Compared to the existing system of floor set microphone stands, the new design is intended to be easier to setup, less obtrusive for the audience, and capable of providing superior sound quality for the purposes of recording performances. After doing research into the acoustics of sound recording in auditoriums, the engineers designed a retractable boom and cable system that drops down from the ceiling to a position just above the conductor. The boom holds a left and right channel microphone at optimal spacing for sound reproduction. Driven by an electric motor, the system was designed to be raised and lowered by the flip of a switch in the control booth.
