We have extensive experience in advising on all environmental aspects related to wind turbines. Since April 2022, we have been accredited to determine the sound power of wind turbines in accordance with the international standard IEC 61400-11. This accreditation guarantees that noise emissions are measured and assessed independently and in accordance with international quality standards.
In the Netherlands, compliance with noise limits is monitored in accordance with the Calculation and Measurement Regulations for Wind Turbines, as included in Appendix 4 of the General Rules for Environmental Management Facilities (Rarim). Depending on the local wind speed distribution, we calculate the annual average sound power, which is used to determine the annual average noise level (Lden) at homes. If necessary, we carry out additional measurements at homes, for example in situations where there is discussion about the contribution of low-frequency noise.
The debate about wind turbines is often highly polarized. That is precisely why establishing the correct facts is essential in order to conduct discussions carefully and on the basis of objective data. In addition to the technical substantiation of noise levels, we also offer policy advice on the integration of wind farms in specific situations.
We can also conduct research and provide advice on other environmental aspects, such as external safety and shadow flicker. In this way, we support clients in the careful and responsible realization of wind energy projects.
