3.1.2 Calculation and assessment foundations
The calculation and assessment foundations for meeting the legal requirements of noise protection are laid down in acts or the DIN norms and directives mentioned therein. In the context of road and railway noise, these norms and ordinances are the
following:
-
DIN 18005-1 Noise abatement in town planning
(estimation procedure)
-
RLS-90 Guidelines for noise protection at roads
-
SCHALL 03 Guideline of the German Federal Railways (Deutsche Bundesbahn, DB) for the calculation of the sound immission of railways
-
16th Federal Immission Control Ordinance Traffic Noise Ordinance
-
VLärmSchR97 Guideline for traffic noise protection at federal highways of public easement
VLärmSchR97 and the 16th Federal Immission Control Ordinance refer to the method of calculation within RLS-90 and Schall 03. While the former DIN 18005-1 was still based on an older method of calculation, the new DIN 18005-1 also refers to RLS-90. This is why the fundamental coherences of noise calculation are treated in
section 3.1.2.2 (RLS-90) and not in section 3.1.2.1 (DIN 18005-1).
