U radu su prikazane osnovne teorijske postavke i matematički modeli koji su značajni za obradu akustičkih i neakustičkih podataka u procesu određivanja buke mlaznih aviona prema međunarodnom standardu ICAO, Annex 16, za potrebe sertiflkacije. Proces obuhvata i postupak eliminacije efekata ambijentalnog šuma iz signala avionske buke. Kao primer, data je praktična primena navedenog postupka na rezultate merenja za avion G-2A. / This paper presents a basic theoretical scheme and a mathematical model that is used to calculate jet aircraft noise level for certification purposes in accordance with the international standard ICAO Annex 16. In this process acoustic and nonacoustic data are used. The process also includes the procedure for eliminating ambient noise effects out of the aircraft noise signal. This procedure was applied in the case of noise measurement results for the G-2Ajet aircraft.
