Method and active device for dealing with noise on board a vehicle, and vehicle provided with such a device

The device has a position sensor determining a position of a head of a passenger. A treatment unit is connected to a local noise sound sensor to receive a local noise signal, and delivers a control signal to a sound actuator, where the control signal is function of the local noise signal and transfer function per ear and relates to transferring sound waves between a sound actuator and the passenger. An active matching unit co-operates with the sensor to keep the transfer function used in preparing the control signal representative of a path traveled by anti-noise. An independent claim is also included for a method for attenuating noise on a board in a vehicle.
