ABSTRACT:
A method and sound wave generating assembly for keeping a surface free of scale, fouling and dirty generated by the adherence of in water-living organisms such as marine life, the surface being part of a body that is in contact with water, the method comprising the step of generating and emitting, from at least one location of the body, at least one high-frequency sound wave train, forming, adjacent the body surface, a vibrating field encircling the body surface, wherein the molecular kinetic energy of the water within the field is increased to generate a drastic drop in the density of the water as well as in the density of the cells of the organisms entering the vibrating field, thus alterating the habitat of the organisms and discouraging the organisms from adhering to the body surface.
