The Aircraft Noise Working Group (ANSWr), comprised of the NASA, the DLR, and the ONERA, recently completed an analysis campaign to compare aircraft noise simulation tools, establish guidelines for noise prediction, and launched activities to assess uncertainties associated with the simulation. The campaign included the analyses of two DLR conceptual aircraft, a reference tube-and-wing aircraft, and a low noise aircraft with engines mounted above the fuselage-wing-junction. While the total predicted noise for each of the concepts compared favorably between analyses at the peak level, significant differences were noted at the component level. This paper aims to further that effort by auralizing the sounds associated with those predictions. Comparisons are made between the NASA, DLR/Empa, and ONERA generated sounds to determine how differences in the system noise prediction result in changes to the auralized sound.
