Using Electric Drives for Active Sound Generation

MdynamiX, the Affiliated Institute of the Munich University of Applied Sciences, is researching noise generation using electric drives in order apply this approach to acoustic function augmentation in the future. The electric motor virtually becomes a loudspeaker and can thus serve as a so-called Acoustic Vehicle Alerting System (AVAS). Without additional hardware, the applications developed can be used not only to realize the required warning signals for electric vehicles, but also to design brand-specific sounds. The basic functionality of electric drives is not affected or even disturbed.
