Title: Device for sound attenuation in a flow duct

Abstract: A silencer in a flow duct (10) comprises at least one plate-shaped element (12) which extends essentially parallel to the throughflow direction (16) of the flow duct. Integrated in the plate-shaped element (12), preferably in the downstream region, are means (13, 14) for feeding and for spraying a liquid (15) into the throughflow of the flow duct. The spraying means are preferably arranged in such a way that the liquid (15) is sprayed at an angle of at least 30.degree. to the throughflow (16). The silencer according to the invention is used, for example, in the intake duct of a gas turboset.
