Claim:
1. A system for reducing underwater noise, comprising: a solid panel having a thickness at any given location on the panel and having two generally opposing faces of said panel; a plurality of resonator cavities defined within said panel; each resonator cavity having a closed end within said panel and an open end through which an interior of said resonator cavity is in fluid communication with surrounding of said panel; each resonator cavity further defining a volume described by a geometry of said resonator cavity within said panel; and each resonator cavity configured and arranged within said panel so as to have at least a portion of said volume of the resonator cavity disposed higher than said open end so as to be capable of trapping an amount of gas within the resonator cavity when said panel is submerged in a liquid, wherein said volume or said geometry of each resonator cavity varies according to a respective design depth of deployment of said resonator cavity in said liquid.
