Duct sound damper for deliberate reduction of sound waves for a flow machine, particularly for a compressor, with a housing having at least one horizontally extending acoustically reflective back wall and at least one front cover plate. At least one flow channel connected together through inlet opening and outlet opening is enclosed by at least one damper member reducing the sound. The damper member includes horizontal axial stringers, circumferential stringers, the front cover plate, at least one sound-insulating metal element extending horizontal to the flow-guiding cross section, and the acoustically reflective back wall. |
