<p>A sound absorption system is formed in such a way that at least a part of the system is provided with a muff of pressed mineral wool. It thus becomes possible to suppress, for example, exhaust noise, particularly from internal combustion engines which are difficult to sound-proof, by means of very simple and compact silencers in the exhaust system, in that use can be made of silencers without guideways, baffle plates or sound-absorbing plates and of small dimensions, whereby the silencers can be standardized in relation to known silencers and made more simple, less expensive, more effective, and given a longer durability.</p> |
