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.
