A throughflow air duct () extends through the housing. A quarter-wave resonator () in the housing has an elongate resonator duct () which is curved in its longitudinal direction, has at one end an inlet aperture () situated in a wall of the throughflow duct, and has a cross-sectional area larger than or equal to that of the throughflow duct. The other end () of the resonator duct is closed. A motor vehicle has such a silencer device.
