TL;DR: A real-time method for continuously tracking the similarity of the input sound and the aircraft’s sounds so that the monitoring unit will be able to mark aircraft events, or to make measurements only when aircraft sound is louder than background noise.

TL;DR: In this paper, the authors consider the problem of shielding the engines from the ground by means of the aircraft wings and tailplane, and present methods of calculating the shielding effect, as well as the special case of the wing trailing edge where noise may be generated by interaction both with acoustic sources and with jet flow.

01 Nov 2009TL;DR: In this article, noise source separation techniques for the extraction of the subdominant combustion noise from the total noise signatures obtained in static-engine tests are described, and three methods are applied to data from a static, full-scale engine test.
Abstract: Noise-source separation techniques for the extraction of the sub-dominant combustion noise from the total noise signatures obtained in static-engine tests are described. Three methods are applied to data from a static, full-scale engine test. Both 1/3-octave and narrow-band results are discussed. The results are used to assess the combustion-noise prediction capability of the Aircraft Noise Prediction Program (ANOPP). A new additional phase-angle-based discriminator for the three-signal method is also introduced.
