Abstract
The present invention relates to a muffler for an exhaust system of an internal combustion engine. To be able to suppress at least two different frequencies or frequency ranges in a comparatively inexpensive design, the muffler has a housing in which at least two resonator chambers are separated from one another. At least two branch pipes branch off from an exhaust-carrying pipe in a branch section. These branch pipes open into different resonator chambers. The respective resonator chamber forms a Helmholtz resonator with the respective branch pipe, each resonator differing from the others in their different resonance frequencies.
