An acoustics (noise) study could be required for a wind farm or individual turbine to be erected. Wind Minds can monitor noise emissions and the noise burden of wind turbines an how this affects local houses.
Services provided can include the following:
- A general exploratory analysis with noise contours based on distances to houses, the size of a wind farm and the size of the wind turbines. This may serve to substantiate a feasibility study or plan: EIA;
- A comprehensive acoustics report based on model calculations, which may also deal with aspects such as low-frequency noise, cumulative effects and mitigating measures. This may serve to substantiate an EIA, zoning plan or permit application.
Given our in-depth knowledge of the procedures, we ensure that the acoustics reports are in line with the preconditions set out by the competent authorities.
How do you calculate the noise produced by wind turbines?
The noise is calculated by means of a model. When assessing the noise generated by a wind turbine, we look at the noise generated by the blades, the subsoil of the area (does the soil reflect or absorb the noise) and any objects in the area (such as buildings and vegetation). Other sources of noise (environmental noise) such as motorways, railways or industry are also included.
When calculating the noise levels near houses for a specific project, the level is translated into distances on a map; this is referred to as noise contours.
