Title:
無人飛行体
Document Type and Number:
Japanese Patent JP7123630
Kind Code:
B2
Abstract:
To provide a control device capable of expanding a range in which noise generated by an unmanned flying object is suppressed.SOLUTION: A control device 10 includes: a first acquisition unit 11 for acquiring position information on one or more unmanned flying objects 20 and noise information on first noises generated from the one or more unmanned flying objects 20; a second acquisition unit 12 for acquiring output area information indicating an output area A1 of sound output from a speaker 30; a calculation unit 13 for calculating second noises reaching the output area A1 in the first noises generated from the one or more unmanned flying objects 20 using the position information, the output area information, and the noise information; a signal generation unit 14 for generating antiphase signals for outputting antiphase sounds with respect to the calculated second noises; and an output control unit 15 for causing the speaker 30 to output sounds on the basis of the generated antiphase signals.SELECTED DRAWING: Figure 1
