More Information
Summary:The invention relates to a method (30) for damping and/or amplifying a sound introduced into a passenger compartment (10) of a motor vehicle, in particular an electrically driven motor vehicle, said sound being generated (32) by a sound source (22) arranged outside of the passenger compartment (10). A correction signal is generated (40) by means of correction signal means (16) which are paired with the sound source (22) and/or a sound-transmitting structure (20) of the motor vehicle, and the correction signal is determined (38) such that the sound is introduced into the passenger compartment (10) in a damped or amplified state.
