Acoustic Test Facility

This facility consists of an oval, freshwater pond, which measures approximately 240 by 145 feet, and is 20 or 30 feet deep depending on the work area. There is a main building on land with a 100-foot covered test pier and a pontoon barge with an equipment building. Both buildings are instrumented with digital acoustic measuring systems consisting primarily of Hewlett Packard equipment. The measurement system in the main building is transitioning to a VXI data acquisition system. Rotating positioners, capable of handling 1,000 pounds, are located at both test sites, as well as 1-ton overhead hoists. Vinyl plastic liners are suspended beneath both the pier and the barge to provide clear, isothermal water in the work areas. Their dimensions are 38 feet long by 20 feet wide by 20 feet deep at the pier, and 45 feet long by 33 feet wide by 30 feet deep under the barge. Both liners extend to the mud bottom of the pond.
