A study was made of a high power acoustic noise source developed by Professor E. Lubcke of Berlin, Germany. The possibilities of its use for calibrating spaces in manufacturers plants where sound power measurements on machinery are made, and for determining the acoustical properties of ship compartments were examined. The study showed that its use was very limited due to lack of portability and lack of data repeatability caused by wear. Author
