The arrangement comprises at least one pipe (3) which is connected to at least two volumes or openings, e.g. in the form of a noise damper (1) and a channel/pipe outlet (4), in such a way that multiples of waves can arise in the pipe (3) between both volumes/openings. At least one tube is arranged in the pipe, the tube one end comprising an inlet and its other end being wholly or partly closed. The tube inlet is arranged in or near some of the pipe noise pressure areas (P1 max, P2 max) in order to damp at least a noise pressure max. |
