Permissible environmental noise levels are set out in the Regulation of the Minister of the Environment of 14 June 2007 on permissible noise levels in the environment (Dz. U. z 2014 r. poz. 112).
For noise analyses we use SoundPlan Essential 4.1 and our own plugin WTG Noise.
Noise measurements are carried out with a SONOPAN sound level meter that meets the requirements of PN-EN 61672 for class 1.
