HYDROACOUSTIC COATING Russian patent published in 2012 - IPC G10K11/168

Abstract RU 2466467 C1

FIELD: physics.

SUBSTANCE: coating plate is made from two semi-perforated plates connected to each other by a layer of solid rubber, wherein the lower semi-perforated plate has cylindrical cavities reinforced by polymer coils, and the air pockets in the upper semi-perforated plate are cone-shaped. The air pockets in the upper semi-perforated can have different height and different base diameter.

EFFECT: high anti-sonar effect of the hydroacoustic coating with increase in its sound insulation in the low-frequency region.
