Abstract
A device is provided for damping hydrosound in liquid emitted from a sound-emitting body in the liquid. The device includes a plurality of envelope bodies distributed in the liquid in an area of the hydrosound-emitting body and at a distance from each other. A material, diameter and pressure of each envelope body is configured such that a natural frequency of the envelope body corresponds to an emitted frequency range of the hydrosound so as to dampen the hydrosound. The device also includes at least one mass body disposed in the liquid. The envelope bodies are connected to the mass bodies so as to prevent the envelope bodies from rising up in the liquid.
