Machinery Acoustic Silencing Laboratory

This laboratory consists of three large anechoic/quiet rooms with isolated floors containing facilities for the measurement and characterization of low-level airborne, fluidborne, and structureborne generated noise of full-scale shipboard machinery. The large scale machinery anechoic chamber has a 3900 square foot test area and a 50 foot high ceiling; floor loading is 700 pounds per square foot. The total test area of three rooms exceeds 14,000 square feet. Programs to develop quiet machinery technology and prototype hardware for all classes of submarine and surface ships are supported by this laboratory. Research and development is conducted for quiet pumps, fans, ventilation and fluid systems, valves, mounts, electric motors and generators, and other machinery components and systems.
