Abstract

The sound damper is contained in a housing (1) the surface (2) of which has one or more flanges (5,6,7). and at least one inlet (3) and outlet (4) for exhaust gas. The flanges are shaped and or arranged unevenly in order to reduce noise radiation. The irregularities concern the shape or symmetry of the flanges; the size-distribution of the flanges' surfaces in relation to the housing's surface; and the curvature distribution of he flanges' peripheral curves.
