A noise blockage (2) to be mounted in a hollow bodyframe (1) of a vehicle is formed as a partition piece filled with and covered with polyurethane foam. The noise blockage includes a first partition piece (3) with a fixing flange (4) and a second partition piece (3') having a welding protrusion (5) and an opening (6). The two partition pieces are welded each other at the welding protrusion and poly- urethane foam is filled inbetween. This partition piece is welded to the hollow body frame with the fixing flange, and then polyurethane foam is further covered on both sides of the partition piece.
