Under the Environmental Protection Act (USG), emission limits generally have to be set for evaluation of the harmful effects or nuisance. They must be defined so that emissions below these levels do not significantly affect the well-being of the population. The pollution limits in the Noise Abatement Ordinance (LSV) were defined on the basis of these criteria.

The FNAC monitors the evolution of noise pollution and its impact on the health and well-being of the population. If necessary it applies to the Department for measures to be taken.
