ABSTRACT:
A method of providing protection to a substrate or an object near a substrate includes placing a material between the substrate or object and a source of sound waves, the material being a viscoelastic matrix reinforced with rods or fibrous materials. The method is particularly useful when the substrate is an underwater craft or when the object to be protected is a sonar antenna.
