The Federal Aviation Administration approved the installation of Lord
Corporation's NVX Active Noise and Vibration Control System in the DC-9
Series of aircraft.  The Supplimental Type Certificate (ST01241AT) was
issued on January 8, 1997 thereby making NVX the first active noise and
vibration control system to receive FAA approval on a commercial jet
airliner.

The NVX Active Noise and Vibration Control System makes the rear of the
DC-9 cabin as quiet as the front.  This should be a welcomed relief for
passengers.
