In this time lapse video, technicians install wiring inside, and hundreds of small microphones outside, the Boeing Dreamliner 787 being flown for this year’s ecoDemonstrator Program. The microphones are part of a NASA experiment to collect data on the acoustics generated by the interactions of the wing, tail, landing gear, engines with the fuselage of the vehicle – to get a modern, fresh full “soundscape” of noise generated by the entire aircraft. To complete the acoustics picture, Boeing flew the instrumented aircraft over a ground array of more than 900 microphones to collect data from the ground. NASA will use the date to update software used by the aviation community to predict acoustic levels of future airliner designs.
