METHOD AND SYSTEM FOR MONITORING AIRCRAFT NOISE Russian patent published in 2022 - IPC G01H17/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment, in particular, to methods and systems for monitoring aircraft noise. The method is as follows: the source information about the noise from the aircraft noise monitoring point, the trajectories of the aerial vehicle (AV), the weather data, and the technical condition of the data collection, processing, and transmission unit is collected at aircraft noise monitoring points; the AV data is filtered in order to identify only the AVs performing take-off, landing, and manoeuvring operations within the entire plurality of flying AVs for the observation area of interest; the type and course of the performed operation is determined on the basis of the data obtained at the previous stage; the type of AV and the AV information characterising the type of the operation, the course of the operation, and the instantaneous horizontal and vertical velocity are determined on the basis of the trajectory of the AV and the AV ID data; the deviations of routes of the AVs from the established patterns are calculated, the information on the flight path of the AV is compared with the previously obtained information on the noise at the time of passing of the particular AV; the AV noise is isolated from the overall noise at the site of installation of the system; the AV noise isolated at the previous stage is analysed, wherein the statistical parameters of the noise impact on the territory near the sites of installation of the system and in all areas exposed to noise effects in the proximity of the aerodrome are calculated; the information on the courses, routes, and types of operations for the airport where the system is installed are subjected to statistical analysis; the generalised results of operation of the system are compiled, preparing graphic information on the noise, operations of AVs, noise exposure boundaries, and noise situation.

EFFECT: analysis of the acoustic effect of the AVs over selected periods of time both for singular installation sites of the system and for the entire territory of monitoring for the purpose of constructing and affirming the boundaries of noise effect.
