The present invention relates to a resonator for attenuation of preferably low-frequency noises. More specifically, the invention relates to a resonator, wherein the stream is split into one primary stream and one secondary stream, the secondary stream being produced by short-circuiting the flow tube of said stream. In this manner the part of the flow pipe delimited by the short-circuit in which said primary stream flows forms a resonance volume in a resonator of Helmholtz type. Thus, the main part of the stream may be made to flow through the resonance volume and this volume may be used for other types of attenuation. <IMAGE> |
