From the sound source to psycho-acoustic assessment (WEA-Akzeptanz)
|Supervisor:||Günter Groß, Siegfried Raasch|
In recent years, wind energy has been established as the central pillar of the energy turnaround. However, the development of wind farms near densely populated areas can evoke strong disapproval from the local population due to excessive sound immission. Objections from residents have delayed such applications in the past.
The aim of the WEA-Akzeptanz (WT-Acceptance) project is to predict the effects of wind turbine noise on the local population. Therefore, an acoustic model chain (sound generation, sound propagation, sound perception at the immission location) will be developed. The results will help to improve the design process of wind turbines in order to reduce sound emission in the future. The joint research project is carried out by Leibniz Universität Hannover (ISD, ICT and IMUK) in close cooperation with the industrial partner Senvion Holding GmbH.
The IMUK will provide highly resolved spatial and temporal data of the atmospheric boundary layer to its partners in order to take into account the effect of meteorological conditions (such as temperature stratification, wind speed and turbulence) on sound propagation. The data is obtained from numerical simulations with PALM as well as from two measuring campaigns. Within the developed model chain, the meteorological data will be used by the sound propagation model of the ISD.
