Electric vehicles (EVs) are inherently quiet as there is no combustion engine, which is the primary source of noise and vibration in ICE powered vehicles. Therefore, transmissions fitted into EVs are perceived to be noisier than their ICE powered counterparts. Moreover, current EV concepts typically use high rotational speeds to satisfy the power demand, which results in a very large range of excitation frequencies and often produces significant tonal contributions in the emitted noise, which are perceived as particularly unpleasant.
