Emissions level according to Schall 03

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

Calculation form for emissions level according to Schall 03

With the form SCHALL 03, an Octave band and an A-weighted emission level (Lm,E) are calculated according to "Richtlinie zur Berechnung der Schallimmissionen von Schienenwegen, August 1990"
