Abstract:

This investigation is being conducted to develop a damping treatment for destroyer hulls which will reduce the interference of the ships noise with the ships sonar. Tests are described which are considered suitable for incorporation in a performance specification for treatments intended to dampen over the frequency range 2000 to 11,000 cps. The properties of a nitrile rubber damping treatment I and a plastic damping treatment II were measured by these test procedures. Specification limits based on the performance of the 2 damping treatments are proposed. It is shown that I provides better damping than II particularly after aging. The properties and damping efficiency of another nitrile rubber treatment are also described. Author
