ABSTRACT:
An apparatus for preventing the transmission of sound in an underwater medium. A resilient housing encloses at least two voids. A first void contains a compliant tube consisting of two T-shaped support structures, each T-shaped support structure supporting a free-bending span designed to resonate at a predetermined frequency. A second void contains a viscous liquid in which metal fibers are suspended. The resilient housing may be surrounded by a rigid cover material which may include means for fastening the apparatus to a surface. The viscous liquid dissipates sound. The compliant tube attenuates the sound waves and decreases the velocity of the sound waves, consequently decreasing the wavelength of the waves.
