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".


Descriptor is a user defined text, which will be transfered, by pressing OK, together with the results into the appropriate tables.
