Our small wind turbines are quiet.
The Danish company Grontmij has issued a certification that confirms it.
The noise measurements carried out by Grontmij arround our small wind turbines gave the following results:
At a distance of 60 metres and a constant wind of 8 m/s, a noise of 37.1 dB (A) was registered (according to BWEA standards).
That is the same level of noise we find, for example, in a library.
The following table gives a reference of the intensities of the noise generated by some typical sources.
