Primena sistema za monitoring buke i MatLab-a za proračun nivoa avionske buke / Noise monitoring system and MatLab application for aircraft noise level calculation

Abstract

U radu je prikazan način primene sistema za monitoring buke, terminal NMT 3637B i softver 7802, firme Brüel & Kjær, u procesu sertifikacije mlaznih aviona, prema ICAO, standardu Annex 16 i algoritam za proračun EPNL nivoa buke (Effective Perceived Noise Level), koji je kreiran u okruženju MatLab. Ovim softverom sublimirani su svi potrebni ulazni podaci, akustički i neakustički, radi dobijanja traženog nivoa i svih međurezultata neophodnih za formiranje konačnog izveštaja koji se dostavlja vazduhoplovnim vlastima. / This paper presents the use of noise monitoring system, terminal NMT 3637B and software 7802, Brüel & Kjær in process of jet aircraft noise certification according to standard ICAO Annex 16 and the algoritam for calculating EPNL noise level (Effective Perceived Noise Level) that we created in MatLab environment. This software sublimated all necessary input parameters, acoustic and non acoustic in purpose of getting final result and intermediate data. Those data are important for reporting to the certificating authority.
