<p>An active noise control device (12) detects composite vibration of a vibration transmitting route (30) to which both vibration of a rotating body (E) caused by generation or transmission of drive force of a vehicle (10) and vibration of a wheel (26) generated by contact between the wheel (26) and a road surface (R) are transmitted. A first reference signal (Sbc) for defining a reference waveform of a canceling sound (CS) for canceling vibration noise (NZc) in a vehicle interior is generated based on the composite vibration. The component of the canceling sound (CS) for canceling vibration noise (NZe) of the rotating body (E) is removed from the first reference signal (Sbc) to generate a second reference signal (Sbr) for defining a reference waveform of the canceling sound (CS) for canceling vibration noise (NZr) of the wheel (26). The canceling sound (CS) is outputted based on the second reference signal (Sbr).</p> |
