The operation of energy production sites (wind, hydroelectric or biomass) causes noise pollution for the neighbours. However, within the framework of the legislation, the sound activities linked to the operation of a site must not emerge in relation to the pre-existing soundscape. To establish the criteria for maximum permissible sound levels, day and night, most acousticians carry out a measurement campaign. Nevertheless, the acoustic measurements are incomplete since they do not take into account the intrinsic variability of the soundscapes and are studied according to an approach which does not take into account all the values observed. Therefore, these measures are not only not replicable, but also lead to scaling maximalist and expensive solutions. Thanks to the Urbanistic Noise Map® (project developed with ADEME), we establish the criteria for maximum acceptable sound levels according to a database of tens of thousands of similar sites to optimize acoustic solutions and not to depend on measures that cannot be replicated in the event of an appeal. Finally, our method takes into account all sound sources and levels, which in some cases makes it possible to guarantee the operation of wind farms and to calibrate the restraints differently.
