The present disclosure relates to a noise reduction system for an automobile suspension for reducing structurally transmitted noise caused by vibrations generated when a damper of the suspension operates and entering the interior of the automobile. The noise reduction system comprises: a vibration detection unit that is mounted on the suspension damper; an anti-phase vibration generator that is mounted on a top mount portion of a vehicle body on which the suspension damper is mounted and generates vibration in an opposite phase to vibration generated when the damper operates to be applied to the top mount portion; and a control unit that receives a measurement value detected by the vibration detection unit, calculates a target anti-phase vibration, and controls the anti-phase vibration generator.
