The object of the invention is to reduce the propagation of noises, in particular shifting noises in gearboxes. The invention comprises the use of a sintered component in an individualised design as a noise-attenuating component, in particular a gearwheel. In the embodiment according to the invention, an axially symmetrical sintered component includes individual, approximately annular material zones, an inner zone close to the axis and an outer edge zone remote from the axis being very strong and largely pore-free, while the central region is highly porous and comparatively ductile. |
