Abstract

The spatial variation in the sound pressure level in a scale model workroom is changed significantly with the addition of fittings in the room. Overall, small fittings tended to decrease the amount of variation in sound pressure level in the room. Small fittings tended to decrease the variation in sound pressure level more than large fittings, close to the source, while far from the source large fittings decreased the variation more than small fittings.
