Abstract
An absorption silencer, particularly a multi-stage silencer, having a main silencer with a built-in resonator silencer connected upstream of a secondary silencer, the main silencer comprising a directly stressed resonator (8), tuned to low frequencies, with a resonator tube (7) projecting into the exhaust gas flow against the flow direction of the main gas flow. <IMAGE>
