  • Predicting Underwater Noise due to Offshore Pile Driving: Modeling of Noise Reduction Methods (BORA)
    The global target of the joint project BORA is to develop a calculation model to predict waterborne noise due to offshore pile driving. This includes especially models to predict the sound development at the source due to pile deformation and vibration, the sound transmission into water and soil and the consideration of the sound attenuation due to the air-water mixture produced by bubble curtains or due to other sound reduction methods.

  • From the source to the perception
    In the project WEA-Akzeptanz an interdisciplinary approach will be followed, which links the physical sound generation, radiation and propagation with the perception at the immission site. In cooperation with the industrial partner Senvion, the IKT and the IMUK of the Leibniz Universität Hannover, an acoustic overall model will be developed comprising the sound generation at the wind turbine, the sound propagation to the receiver under realistic atmospheric conditions and a perception model.

  • Development of an AI-based Geographic Information System for the Selection of Wind Energy Potential Sites within the Context of Species Conservation, Environmental Protection, and Climate Protection (WindGISKI)
    The aim of the project is to develop and evaluate an AI-based GIS system to identify suitable areas for wind turbines. The identification process will be automated and systematized through the use of modern technologies, with special consideration of immission, environmental, species and climate protection aspects. A significant improvement in both the quality and quantity of potential wind turbine sites is being aimed for. The focus of the ISD includes the combination of a sound simulation model with GIS data and the implementation of a shadow impact simulation.

  • Reallabor – Innovation area V – Subproject V.3 (Reallabor IB5 TP V.3)
    In subproject V.3, an acoustic model of an offshore wind farm will be developed, encompassing all relevant noise sources that may occur throughout its lifetime. The model is intended to be integrated with a hydrodynamic model of the North Sea to account for the influence of environmental conditions. In addition to the modeling work, extensive field measurements will be conducted in an offshore wind farm. These data will be used both to accurately specify the characteristics of the noise sources and to validate the model. The overarching goal is to enable precise, scenario-based assessments of underwater noise pollution and its ecological impacts.
