Abstract

In 2008 a revised version of the German aircraft noise calculation procedure AzB was published. It provides a source model based on octave spectra and an explicit directivity description. This allows a flexible and extendable source description that is clearly separated from the sound propagation model. The AzB uses a segmentation technique similar to that described in the 3rd edition of ECAC Doc.29. However the model was developed to calculate noise zones based on forecasted air traffic scenarios – a use for bygone scenarios was not intended. This is reflected in the structure of the AzB database that consists only of a relative small number of aircraft categories which are representative for German airports. The source and propagation modelling described in ECAC Doc.29 is not as flexible as the AzB approach. However Doc.29 offers a much higher flexibility in flight performance modelling and takes advantage of the comprehensive and standardised international aircraft noise and performance database ANP. It was obvious to combine the best qualities of Doc.29 and AzB to set up an aircraft noise calculation procedure that extends the current best practice and accounts for the experiences made during the last decade of aircraft noise modelling. This is the primary goal of the new German DIN 45689. The paper gives an overview on the current and planned work on this standard.
