A vehicle HVAC noise control system includes an air handler, a blower motor, an audio event device and a controller. The air handler is connected to a passenger compartment. The blower motor is operably connected to the air handler to provide a plurality of airflow rates for air flowing into a passenger compartment. The audio event device produces an audio event to the passenger compartment. The controller is operatively connected to the blower motor and the audio event device. The controller controls operation of the blower motor initially at an operating airflow rate and subsequently switches to a noise reducing airflow rate in response to a signal from the audio event device indicating that the audio event device will subsequently produce the audio event.
