METHOD OF MEASUREMENT OF AIRCRAFT NOISE IN FLIGHT AND AUTOMATIC ELIMINATION OF NOISE NOT COMING FROM AIRCRAFT.

摘要

Aircraft noise measurement method inoverflight and automatic noise removal not coming fromaircraft;It is about adapting a technique ofmeasurement of existing noise to the specific application of measurement ofairplane noise overflight. The original technique consists ofhave a network of microphones in space and, through thesignal processing, locate and quantify the differentnoise sources present in an acoustic field.;The object of this patent is geometryconcrete distribution of microphones that allows reductionof the number of microphones to use only twelve and theComplementation of the processing method with an additional stepwhich compensates for the lack of resolution that would otherwise entailsaid reduction.;The technical problem that solves this method isto obtain a measurement of aircraft noise without affecting thebackground noise of the place of measurement.
