In a method for operating an internal combustion engine, in particular an auto-ignition internal combustion engine, having at least one combustion chamber in which an air/fuel mixture is formed, and recirculated exhaust gas is admixed to the combustion air, a base setting of the exhaust gas recirculation rate is established as a function of a first characteristic operating variable, the exhaust gas recirculation rate is adjusted depending on at least one of the first and a second characteristic operating variable, and, in order to optimize combustion, the exhaust gas recirculation rate is adjusted a second time on the basis of a combustion noise measurement.
