  • Device for reducing airborne and structure-borne sound
    Patent number: 11727911
    Abstract: A device for reducing airborne and structure-borne sound has a flow channel with a flow channel wall (22, 22?, 22?) and at least one resonator chamber (40, 40?, 40?) adjacent the flow channel wall (22, 22?, 22?). The flow channel wall is formed by a sound absorber (30, 30?, 30?) at least in a part bordering the resonator chamber (40, 40?, 40?). The sound absorber (30, 30?, 30?) is covered towards the resonator chamber (40, 40?, 40?) by an acoustically reflecting inner wall (42, 42?, 42?) of the resonator chamber with at least one wall aperture (44, 44?, 44?). Openings (32, 32?, 32?) completely covers the wall aperture (44, 44?, 44?) of the inner wall (42, 42?, 42?) of the resonator chamber such that sound waves flowing through the flow channel must pass the sound absorber (30, 30?, 30?) to enter the resonator chamber (40, 40?, 40?).
