• Resumen

  • The European Environmental Noise Directive END requires harmonized prediction methods for the major environmental noise sources. Currently two potential candidates are discussed for the modelling of aircraft noise: the 3rd edition of ECAC Doc.29 was published in 2005 describing a recommended method for the prediction of aircraft noise around civil airports. The German AzB model published in 2008 was developed as a tool for the enforcement of the revised German Act for Protection against Aircraft Noise that came into force in 2007. This paper gives a comparative overview on both methods, the underlying acoustic and aircraft performance models and their usability for different fields of application.
