A noise dampening arrangement for a motor vehicle includes a mass coupled to a structural component of the motor vehicle. A sensor detects vibration of the structural component of the motor vehicle, and transmits a vibration signal indicative of the detected vibration. An electronic processor is communicatively coupled to the sensor, receives the vibration signal, and emits a vibration compensation signal dependent upon the vibration signal. An actuator is communicatively coupled to the electronic processor, receives the vibration compensation signal, and exerts a force on the mass dependent upon the vibration compensation signal such that the vibration of the structural component of the motor vehicle is reduced.
