An electronic device includes an enclosure for the electronic device and a duct extending from an interior to an exterior of the enclosure to exhaust airflow from the enclosure. The electronic device further includes an active noise control mechanism. The active noise control mechanism includes an internal sensor, an external sensor, and an acoustic wave generator. The internal sensor is arranged within the enclosure to sense a noise and generate an internal sensor output, and the external sensor is arranged outside of the enclosure to detect sounds and generate an external sensor output. Based on the internal sensor output and the external sensor output, the acoustic wave generator generates an acoustic wave within the duct to reduce the noise.
