An active vibration noise control apparatus (12, 12a, 12b) comprising: a front road wheel vibration detecting unit (60x, 60y, 60z) configured to detect a front road vibration based on a road input to a front road wheel of a vehicle (10, 10A, 10B) and output a front road wheel reference signal representing the detected front road wheel vibration; a vehicle speed detecting unit configured to detect a vehicle speed of the vehicle (10, 10A, 10B); a delay time calculating unit configured to determine a delay time which represents a difference between times at which the front road wheel of the vehicle (10, 10A, 10B) and a rear road wheel thereof pass through one spot; a rear road wheel reference signal output unit configured to output a rear road wheel reference signal representing a predicted rear road wheel vibration which is a delayed front road wheel vibration for the delay time; and a control signal generator comprising: a filtering unit (70a, 70b) configured to output, based on the front road wheel reference signal, a front road wheel canceling sound signal for canceling a front road wheel vibration noise due to the front road wheel vibration at a sound silencing target position, and to output, based on the rear road wheel reference signal, a rear road wheel canceling sound signal for canceling a rear road wheel vibration noise due to the predicted rear road wheel vibration at the sound silencing target position, and combining means configured to combine the front road wheel canceling sound signal with the rear road wheel canceling sound signal and configured to output a combined signal (Scr), and an output unit configured to output said combined signal (Scr), characterized by a steered state detecting unit configured to detect a steered state of the vehicle (10, 10A, 10B); reducing means (78, 90, 92) configured to reduce the rear road wheel canceling sound when the control signal generator detects that a path followed by the front road wheel and a path followed by the rear road wheel are different from each other based on the steered state, wherein the combining means is configured to combine the front road wheel canceling sound signal with the rear road wheel canceling sound signal being reduced by the reducing means when the control signal generator detects that a path followed by the front road wheel and a path followed by the rear road wheel are different from each other based on the steered state, to output said combined signal (Scr). a front road wheel vibration detecting unit (60x, 60y, 60z) configured to detect a front road vibration based on a road input to a front road wheel of a vehicle (10, 10A, 10B) and output a front road wheel reference signal representing the detected front road wheel vibration;
