摘要:
An active noise control system (100) and method modifies a noise made when a vehicle closure, such as a door, hood, or trunk, closes by detecting the closure's velocity and selecting a delay time and control noise amplitude appropriate for the velocity. By modifying the noise of a vehicle door closing, the system (100) can reduce the frequency and reverberation of the noise generated by the door, improving user perception of the vehicle itself.
