AIRPORT NOISE EXPOSURE ESTIMATION. FINAL REPORT
Aircraft traffic noise was examined in relation to its predictive estimation. The basic properties of an exposure are shown to be mainly defined by the statistics of near-levels and noise durations. The relationship between these was derived and used to develop a method for the prediction of various noise index quantities such as NNI (Noise Number Index), leq (equivalent continuous energy levels), L sub NP (noise pollution level) LIO (level exceeded for 10%) etc., based on information usually acquired for an NNI assessment. The under leq is shown to be expressible in a form similar to NNI.
