Accuracy of outdoor sound propagation prediction in a complex environment using some reference numerical models
The paper presents principles which can be used in reference numerical models to make easy calculations for predicting long-range outdoor sound propagation under complex environment. Limits, assumptions as well as approximations used are discussed here in terms of accuracy for typical road traffic configurations, depending on range of frequency, geometry of the site and atmospheric conditions. Part of this work has been achieved during the European Project Harmonoise.
