Drones and eVTOL will definitely be a part of the city of tomorrow. How big a part they will play strongly depends on community noise management and acceptance from city populations. This paper proposes a comprehensive process to simulate, study and reduce the annoyance of such noise sources. A large part of the noise is coming from the rotor blades and can be simulated with aeroacoustics computation tools, which also account for the interferences produced between several rotors. Other sources such as the e-motor also play an important role that need to be considered. The impact of the propagation of these source noises towards the ground is quite different at small and large distances, and different modeling approaches can be used (source directivities, atmospheric absorption, turbulence, etc.). Then, various techniques can be employed for the spatial sound rendering of the noise perceived on the ground; this paper considers two approaches: binaural rending over headphones and Vector-Base Amplitude Panning with a multiple-speaker system. Finally, psychoacoustics indicators can be calculated on the simulated noise and then compared to listening test results.
