Noise Measurement of the Multicopter UAV

The work is devoted to the measurement of noise characteristics of the unmanned aerial vehicle in laboratory and field conditions, using standard methods and measuring instruments operating in the field of acoustic pressure and the original sound locator device for detecting a unmanned aerial vehicle operating both in the field of pressure and in the field of vibrational velocity. The spectral densities of amplitudes, spectral levels and the values of the intensity of the acoustic noise produced by the unmanned aerial vehicle have been analyzed. The methods of broadband and narrowband spectral analysis and the ideology of mutual spectra are used in this work. The task of installing a bearing on an air object is solved. The structure, principle of operation and display of the measurement results of the device is realized using the LabView instrumental laboratory package.
