Abstract:

To predict aircraft noise according to aircraft tracks, the aircraft tracks are divided into two basic track elements based on their geometric characteristics, i.e. the straight line tracks and the curve line tracks, and then the noise contribution of the straight line track and the curve line track are calculated respectively for their area of influence. After a statistical treatment of the noise impact on all segments of the track monitoring points, the noise finally comes together to affect the entire track segment monitoring points. Thus an aircraft track noise prediction model is established in this paper. Compared with similar prediction software and the actual monitoring data, the predicted average noise values of the present model are relatively accurate, and the predicted noise peak values are more accurate.

Key words: flight track, aircraft noise, noise intensity, prediction model, noise prediction
