The Institute of Atmospheric Physics develops and operates advanced sound propagation models. In combination with meteorological mesoscale and microscale models they describe the system of atmosphere, topography and sound waves in a consistent manner. The models are used for scientific studies of the influence of complex terrain and topographical features (valleys, street canyons, vegetation, etc.) under realistic meteorological conditions. They can be used to optimize noise protection measures. Moreover, the models can be used to derive simplified noise prediction procedures.
Two different types of sound particle models are currently in use:
The sound propagation models are used mainly in the context of traffic noise or the sound of wind turbines.
