Abstract
A method for masking and/or reducing disturbing noises or the conspicuousness thereof when a motor vehicle is being operated includes forming a compensation signal and/or a heterodyne signal based on disturbing noises that are detected in acceleration measurement signals that are received or based on operating states of the motor vehicle or at least of a component of the motor vehicle and using the compensation signal and/or heterodyne signal to modulate an existing control signal of an actuator of the motor vehicle such that the disturbing noises or conspicuousness thereof are reduced and/or at least in part masked. The method further includes influencing the heterodyne signal with a broadband signal or a tonal signal having the predetermined frequencies or arrangements such that the disturbing noises is masked or the conspicuousness of the disturbing noises are reduced.
