Abstract (en)

[origin: EP0649982A1] In order in the case of side branch resonator to achieve good damping (attenuation) of the suction noise cost effectively in a wide frequency range, the natural frequency of the resonator is adapted (matched) to the respective excitation frequency by automatically changing the geometry of its vibrating space (treadmill). For this purpose, the resonator is preferably designed as a bellows (4) having a defined spring characteristic. <IMAGE>
