Unmanned aerial vehicle noise annoyance degree control method based on sound masking principle

Abstract

The invention relates to the technical field of sound masking noise control, in particular to an unmanned aerial vehicle noise annoyance degree control method based on a sound masking principle, and the method comprises the steps: obtaining data; determining a noise annoyance degree; calculating an actual annoyance degree; determining a standard annoyance degree; determining a temporary sound source; determining a marked sound source; determining a target sound source; and adjusting a threshold value and outputting a target sound source. Real-time flight data are integrated into actual annoyance degree calculation, a sound source is pre-screened and masked through bionic superposition of the annoyance degree, the sound source which is most harmonious with the environment is selected by calculating the sound scene fusion degree, and meanwhile, the complaint rate is introduced to dynamically adjust an internal threshold value, so that the crossing from static noise control to dynamic sound scene management is realized; the long-term and effective applicability of the technology in a real urban environment is ensured, the target sound source is finally played, and the problems of low noise reduction effect and response speed lag caused by excessive dependence on a single physical acoustic index and a static control model are effectively solved.
