[origin: WO02057616A1] The invention relates to a sound absorber (1) mounted on or in a component (7), wherein a sound which is to be absorbed is propagated. The silencer (1) comprises a hollow body (8), which communicates with the component (7) or forms a component part of said component (7). A plurality of Helmholtz resonators (10) which operate in a parallel manner are arranged behind each other in the axial direction of the hollow body (8) in at least one axial part (9) of said hollow body (8).
