Abstract
Radiated noises from sonar dome structures are reduced by the use of an erior damping material applied over the dome skin. The damping material is bonded to the outside of a steel sonar dome that is subjected to a seawater environment. An antifouling rubber sheet is bonded over the damping material. The system is particularly applicable to an existing internal punchplate type of sonar dome that does not allow the installation of damping materials on the internal window area of the dome.
Claims2

- a metallic sonar dome;
- a calcium carbonate and carbon loaded nitrile rubber material affixed to and enclosing the exterior surface of said sonar dome;
- and
- a neoprene rubber sheet including tribulyltin oxide as an antifouling agent affixed to and enclosing said loaded nitrile rubber material.
