Abstract: The invention relates to a method (300) and a device (170) for reducing mechanical loads in a powertrain (100). An electric machine (130) is provided as the drive assembly of the powertrain (100), and an inverter (110) is provided in order to output a multiphase output voltage for supplying the electric machine (130). The method (300) has the following steps: determining (320) the multiphase output voltage (UA) for operating the electric machine (130); adding (340) a specifiable voltage (VU) and the specified output voltage (UA); and outputting (350) the sum (SU) of the multiphase output voltage (UA) and the specifiable voltage (VU) in order to supply the electric machine (130).

Abstract: 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.
