Abstract: A silencer comprising one or more sound-absorbing parts of ceramic material. The ceramic material is porous and the sound-absorbing parts are self-supporting and have a specific resistance to air flow of 10.sup.3 -10.sup.7 Pas/m.sup.2 and a compression strength of at least 40 kN/m.sup.2, preferably at least 400 kN/m.sup.2.
