Comparison between impementations of European noise mapping methods

In the context of the European Environmental Noise Directive (2002/49/EC), EU Member States were required to prepare noise maps using interim methods for each noise source or national methods provided that these are equivalent to the interim ones. Concerning the issue on equivalence, in 2008 DG Joint Research Centre provided DG ENV with a technical advice on how to perform the exercise on the equivalence. To verify the equivalence of the results when using different assessment methods, four protocols one for each noise source (i.e., road traffic noise, railway traffic noise, aircraft noise and industrial noise) were prepared by the JRC and delivered to the EU MS. The protocols for road traffic, railway traffic and industrial noise consisted of test situations including terrain shape and ground absorption, different buildings, noise barriers, meteorological conditions and source conditions. They were developed having in mind a set of reasonably real and average test situations which are commonly encountered in urban and suburban areas in Europe. For aircraft noise, three cases were prepared for testing different approaches and departures of aircrafts. In this paper, the aforementioned test situations were used to assess the potential different software implementations of a given method. The analysis consists in calculating the overall standard deviation resulted from differences in noise levels due to different software implementation of a given method for a combination of cross sections and source configuration.
