Boeing Tests Quiet Tech for Airliners
SEATTLE, November 14, 2005, An ANA (All Nippon Airways) 777-300ER flies low over 614 microphones on the runway at Glasgow, Montana, where Boeing Commercial Airplanes and its industry partners conducted a flight-test program proving new noise reduction technologies.
The microphones were used to visualize and record noise levels of the passing airplane. According to Boeing, engine fan-duct modifications and chevron exhaust designs achieved significant airplane cabin and community noise reductions.
