ACTIVE SOUND ATTENUATION FOR AIRCRAFT ELECTRICAL SYSTEM

A method is provided for operating an aircraft system. During this method, an electric machine (46) of an electrical system (68) is operated onboard an aircraft (20). A first set of electrical system waves produced by the electrical system is sensed. A set of electrical system attenuation waves is p...

Zusammenfassung:	A method is provided for operating an aircraft system. During this method, an electric machine (46) of an electrical system (68) is operated onboard an aircraft (20). A first set of electrical system waves produced by the electrical system is sensed. A set of electrical system attenuation waves is produced to attenuate a second set of electrical system waves produced by the electrical system (68) in response to sensing the first set of the electrical system waves.
