A motor vehicle acoustic noise reduction system is provided. The acoustic noise reduction system particularly reduces or eliminates wind throb in a moving vehicle. The system includes a window sensor operable to sense when a first window of the motor vehicle is open. An air inlet is also included which is actuatable to let air into the motor vehicle when the air inlet is in an open position. An actuator associated with and operable to open or close the air inlet is provided and in communication with a controller. The controller is associated with tie sensor and can energize the actuator to place the air inlet in the open position and let air into the motor vehicle when the window sensor senses the first window is in the open position and communicates this information to the controller.
