内容記述 | A microphone array comprised of 195 microphones was expanded at Noto Airport, and flyover tests on noise source localization around the aircraft were carried out with JAXA flying test bed ‘Hisho’. Analysis condition of time domain beamforming method is adjusted properly, which improves both resolution of noise source and signal-to-noise ratio. In the landing configuration, a nose gear, main gears, and edges of flaps are proved to be main noise sources. Integration of noise source maps obtained by beamforming gives good agreement with sound pressure level measured by a microphone placed at the center of the microphone array. | |||||
