A correct evaluation of the sound emissions of the starting and landing passenger planes is realized on the basis of local three level histograms, which take into account meteorological and topographic sound broadening conditions. The process was analyzed by the system NOISIMSIS (Noise Impact Simulation System), whose principle is to consider the air traffic as a sum of single flight events, which are represented by a sequence of discrete emission points. The correlation of measured and forecast third level spectra were satisfying in the 50 to 250 Hz frequency area.
