Test scenarios for the determination of sound emissions

In order to improve the noise situation in Europe, the EU issued the Environmental Noise Directive (2002/49/EC) in 2002. Noise pollution is to be determined in noise maps by means of harmonized assessment methods. For this purpose, the EU has developed these methods under the acronym CNOSSOS-EU (Common Noise Assessment Methods in Europe) with the participation of the Member States. A quality assurance of noise calculations in accordance with DIN 45687 is mandatory. In this documentation, the methods for the determination of sound emissions, the calculation of sound propagation and the assessment of noise exposure are applied to exemplary scenarios.
