# Commission Directive (EU) 2015/996 of 19 May 2015 establishing common noise assessment methods according to Directive 2002/49/EC of the European Parliament and of the Council (Text with EEA relevance), Appendix H: Database for industrial source

Extent: E+W+S+N.I.

This appendix presents a few examples for input values for some industrial noise sources that may be used to calculate industrial noise following the method described in 2.4 Industrial noise. As industrial noise sources are extremely specific for each industrial site, appropriate values are obtained from local, national or international databases or measurements as appropriate.
Table H-1
Coefficients LW, LW' and ΔLW,dir,xyz (x, y, z) for sound power
ΔLW,dir,xyz (x, y, z)=0
LW' is expressed as sound power per metre for line source, or per squared metre for area source.
