Nowadays, the use of quadcopter UAVs is becoming increasingly popular in a wide range of civil applications. Another promising application for quadcopter UAVs would be to perform automated room acoustic measurements with high spatial resolution. Obviously, the flight noise of a quadcopter UAV has a considerable influence on the quality of a room acoustic measurement.This contribution presents a feasibility study regarding the determination of room acoustic parameters by room impulse response measurements under the influence of flight noise from a quadcopter UAV. For this purpose, directional flight noise radiation characteristics of the quadcopter UAV are determined in a first step. On the basis of the directional radiation characteristics, an optimal position of the measurement microphone/s to be placed on the quadcopter UAV can thus be determined. In a second step, existing room impulse responses are subjected to flight noise from the quadcopter UAV and noise compensation techniques are validated using these synthesized data. Finally, room acoustic measurements are performed with and without present flight noise from the quadcopter UAV. These measurements are used to evaluate the quality of the room acoustic measures as a function of the noise present due to the quadcopter UAV.
