Description: Das Projekt "HARMONISED,accurate and reliable prediction methods for the eu directive on the assessment and management of environmental noise (HARMONOISE)" wird vom Umweltbundesamt gefördert und von Deutsches Zentrum für Luft- und Raumfahrt e.V. (DLR), Institut für Physik der Atmosphäre Oberpfaffenhofen durchgeführt. Objective: The European commission has recently published the Draft Directive on the Assessment and Management of Environmental Noise. The commission announces, e.g. in article 1 that intelligent, common, harmonised computation methods with ensured accuracy need to be developed. None of the many existing methods in the Member States satisfies these requirements. The HARMONOISE project intends to develop and validate such methods for the Assessment and Management of Noise from Road and Rail Traffic. The project will build on the most recent scientific achievements in all Member States and will also provide consensus amongst future users throughout the EC. For this purpose the Consortium has a wide international and scientific background. The methods to be provided will be implemented as obligatory under the Directive and will thus find a wide use for purposes of noise planning, mapping, zoning, noise abatement measures and strategies and for compliance checks. Objectives: 1. To develop methods by which the sound power output and the directivity of sources of road and rail traffic can be described and assessed as an accurate physical quantity which is independent of short distance sound propagation; 2. To establish a better correlation with future legislation on limiting the noise generation; 3. To define the format of databases by which source dependent data and location dependent data can be collected and stored; 4. To define the minimum set of meteorological conditions which are to be distinguished in order to derive the long term average noise indicator Lden for 3 different periods of the day (day, evening, night) with sufficient accuracy; 5. To apply advanced scientific tools to model and describe the sound propagation under these conditions;6. To validate the models against empirical data of the highest level of definition; 7. To integrate the above steps into one system of methods to be applied by users anywhere in the EC. Work description: Prediction methods for environmental noise from road and rail traffic and from industrial sources are available in various EU member states. These methods show many lacunae: some of them cannot produce the harmonised noise indicator Lden; others show insufficiencies in e.g. the separation of source power output and propagation (usually leading to different propagation models for different sources, which can not be justified from a scientific point of view). Complicated propagation conditions (e.g. multiple reflections in built up areas) show low accuracy. The Harmonoise project will collect the empirical data on which the existing methods were based as well as the models themselves and use these as a starting point for improvement and harmonisation. The source description will be based on true physical quantities (sound power level, directivity), independent of the propagation conditions.
