摘要： A computer implemented method of distributing noise exposures to unmanned aerial vehicles (UAVs) over a neighborhood includes: receiving flight routing requests to fly the UAVs over the neighborhood; accessing a noise exposure map stored in a noise exposure database in response to the flight routing requests; and generating new flight paths for the UAVs over the neighborhood that load level additional noise exposures that the new flight paths will contribute to the noise exposure map. The noise exposure map includes noise exposure values indexed to properties within the neighborhood. The noise exposure values quantify cumulative noise exposures of the properties due to historical flight paths of the UAVs over the neighborhood.

摘要： A technique of controlling tonal noises produced by an unmanned aerial vehicle (UAV) includes generating thrust with a plurality of rotor units mounted to the UAV to propel the UAV into flight. Each of the rotor units includes a bladed rotor. A rotation rate or a phase delay of at least one of the rotor units is adjusted relative to another of the rotor units. The adjustment causes a spread in the tonal noises generated by the rotor units.
