The invention relates to a device (3) for damping and scattering hydrosound and wave movements in a liquid, particularly water (8), by means of an envelope body (1) enclosing a gas. The aim of the invention is to provide a device (3) by means of which the transmission and propagation of sound and wave movements in water (8) can be reduced, wherein the device (3) can be used either in stretches of standing water or in strong currents in a faultless and controlled manner and has low energy demands and minimizes operating costs independent of water depth. A large-scale use at low cost is also possible. This problem is solved by a device (3) which comprises several envelope bodies (1), each of which contains gas, a carrier element (2) and a mass element (10), wherein the envelope bodies (1) are arranged on the carrier element (2) at a distance from each other. The mass element (10) prevents the gas contained in the envelope body (1) from rising inside the water, whereby the gas volumes remain the same and do not have to be constantly renewed. A complex supply of compressed air, particularly for offshore use and and in the event of large depths of water, is not required. This makes it possible that the gas remains bubble-shaped and is maintained independent of prevailing environmental conditions in the water, such as current or water pressure. The gas enclosed in the envelope body (1) cannot fusion with another gas bubble or divide itself. |
