An active road noise control system and method for a vehicle includes generating a microphone sense signal representative of road noise occurring in or at a wheel well of the vehicle, and iteratively and adaptively processing the microphone sense signal to provide a noise reducing signal. The system and method further include generating from the noise reducing signal with a headrest loudspeaker arrangement disposed in a headrest in an interior of the vehicle, noise reducing sound at a listening position in the interior of the vehicle.
