Abstract
A device for damping hydrosound in liquid having a frequency range emitted from a sound-emitting body in the liquid includes: a plurality of individual gas volumes distributed in the liquid in an area of the sound-emitting body and at a distance from each other, each of the individual gas volumes being operable to reduce the hydrosound through resonant oscillations; and at least one mass body disposed in the liquid, the individual gas volumes being connected to the at least one mass body so as to prevent the individual gas volumes from rising up in the liquid.
