Abstract (in Japanese) (See Japanese page) 
(in English) We are studying a method to reduce rotor noise in acquihired sound using a microphone attached to a multi copter drone. By distancing the microphone from the drone and by hanging from it and using coaxial bipolar null beamforming to suppress rotor noise, the rotor noise level could be down to lower than annoying level. Sound acquisition by a microphone hang from a drone has various potential applications.
