The invention relates to a device (1, 1', 1") for reducing airborne and structure-borne sound having at least one resonator chamber (2, 13, 14, 20, 21, 22, 23) arranged between a supply (7, 7") and a discharge (8, 8"), wherein the resonator chamber is delimited transverse to a longitu
The invention relates to a device (1, 1', 1") for reducing airborne and structure-borne sound having at least one resonator chamber (2, 13, 14, 20, 21, 22, 23) arranged between a supply (7, 7") and a discharge (8, 8"), wherein the resonator chamber is delimited transverse to a longitudinal direction (9, 9") outwards by an outer wall (3', 3', 3") and inwards by an inner wall (4, 4', 4"), wherein the resonator chamber (2, 13, 14, 20, 21, 22, 23) is delimited in the longitudinal direction by a first end wall (5, 15) and a second end wall (6, 16, 17) spaced apart therefrom, and wherein the inner wall (4, 4', 4") is designed to be air-permeable with respect to the adjacent resonator chamber (2, 13, 14, 20, 21, 22, 23). The invention is characterized in that the inner wall (4, 4', 4") is designed to be sound-absorbing by a predetermined permeability in the region of the at least one resonator chamber (2, 13, 14, 20, 21, 22, 23).
