Aircraft noise is a significant problem for communities surrounding airports. Accurate prediction models are needed to estimate levels from aircraft operations. In this research, the accuracy of sonAIR model in predicting departures around Schiphol airport evaluated by comparison measurement data NOMOS and current best-practice modelling approach Doc29. Results show but consistent underestimation sonAIR, mainly due generalisation emission models. The standard deviation differences between...

In best-practice models, such as Doc.29, change expected sound level on ground due to changing atmosphere modelled with a simplified propagation calculation. The Aircraft Noise Performance (ANP) database contains several standardised source spectra, known spectral classes, which are...
