Abstract:The paper proposes a method for calculating the limits of audibility of multirotor systems such as quad- and hexacopters. The components of the proposed methodology are data on the noise of the device and the ambient noise, as well as the criterion of the audibility of the device. The acoustic-vortex method is used to simulate the tonal noise of multirotor systems. A trailing edge noise model is used to calculate the broadband noise of propellers.
