P&K 2714

Emission level according to RLS 90

P&K 2714: Support temporary suspended for review / Unterstützung vorübergehend für Revision ausgesetzt

Calculation form for emission level according to RLS 90

With the form RLS-90, an Octave band and an A-weighted emission level (Lm,E) are calculated according to "Richtlinie für den Lärmschutz an Straßen, August 1990".
