Other Applications of Active Noise Cancellation

    There are many applications of active noise cancellation.  These applications include quieting industrial fans, heating, ventilation and air conditioning ducts, vehicle exhaust, the interior of cars, the inside of air craft including the SAAB 2000 and the Dash 8-Q400, submarines, and headphones.  The headphones are widely in use commercially for music, for pilots, passengers, and air traffic controllers, as well as US Army tanks crews.

Noise Canceling Headphones on a Plane
    Good models can usually cut sound in higher frequencies passively by 15-20 decibels and another 10-20 decibels in lower frequencies by using active noise control. This helps makes active noise cancellation headphones well suited for airplanes.
