Noise emissions are one of the major challenges for modern commercial drones, especially in urban environments where tonal rotor noise is perceived as particularly disturbing. In multi-rotor UAVs, complex interactions between rotors and the vehicle body strongly influence both aerodynamic performance and acoustic radiation.
