Abstract
A damping device for reducing the vibration amplitude of acoustic waves and a burner for operating an internal combustion engine, the burner having a mixing region, in which an air flow and a fuel flow are mixed with one another to form an air/fuel mixture, and a combustion chamber, which in the direction of flow of the fuel/air mixture is arranged downstream of the mixing region, in which the fuel/air mixture can be ignited. A Helmholtz resonator directly connected to the mixing region of the burner such that acoustic waves formed in the burner are suppressed in the Helmholtz resonator and are not reflected back into the burner.
