Method for operating an engine order cancellation system (EOC system), which, on the basis of system-side operating parameters, serves to generate compensation signals used to compensate for acoustic interference signals resulting from the operation of a motor vehicle-side drive unit, comprising the following steps: - detecting of all output audio signals to be output via at least one audio output device comprising at least one audio output element into an interior of a motor vehicle, in particular a passenger compartment of a motor vehicle, - generating a sum signal describing all recorded audio signals, - extracting the spectral components of the sum signal, which may have been prefiltered, the frequencies of which correspond to the frequencies of the acoustic interference signals to be compensated or compensated for by the EOC system, wherein the frequencies of the acoustic interference signals to be compensated or compensated by the EOC system are known; - modifying the respective extracted spectral components to generate modified spectral components, characterized by - converting the modified spectral components into an operating parameter of the EOC system, wherein the operating parameter is the forgetting factor or the step size, - comparing the operating parameter of the EOC system with a comparative operating parameter, - selecting the operating parameter having the most influence on the performance of the EOC system and/or the stability of the EOC system on the basis of the comparison, - operation of the EOC system using the selected operating parameter wherein the modification of the detected spectral components for the generation of modified spectral components is effected by generating an additional input amplification in the region of a first increase of the respective spectral component in the time domain, and/or the modification of the respective detected spectral components for the generation of modified spectral components is effected by time extension of the respective spectral component in the region of a descent of the respective spectral component in the time domain. - detecting of all output audio signals to be output via at least one audio output device comprising at least one audio output element into an interior of a motor vehicle, in particular a passenger compartment of a motor vehicle, - generating a sum signal describing all recorded audio signals, - extracting the spectral components of the sum signal, which may have been prefiltered, the frequencies of which correspond to the frequencies of the acoustic interference signals to be compensated or compensated for by the EOC system, wherein the frequencies of the acoustic interference signals to be compensated or compensated by the EOC system are known; - modifying the respective extracted spectral components to generate modified spectral components, characterized by - converting the modified spectral components into an operating parameter of the EOC system, wherein the operating parameter is the forgetting factor or the step size, - comparing the operating parameter of the EOC system with a comparative operating parameter, - selecting the operating parameter having the most influence on the performance of the EOC system and/or the stability of the EOC system on the basis of the comparison, - operation of the EOC system using the selected operating parameter wherein
