The association between the noise exposure and its effects are determined in large-scale surveys or epidemiological studies. The results from such studies form the basis for defining the exposure limits. The Commission sets out its recommendations for determining the rating levels and exposure limits in 7 reports. The recommendations for road and rail traffic noise, industrial and commercial noise and noise from civil airports and military airports and shooting ranges have all been incorporated in the Noise Abatement Ordinance (LSV).

The commission regularly reviews whether the evaluation methods and pollution limits for noise need to be revised.
