X1, Y1, Z1, X2, Y2 and Z2

Location of the source in a 3-dimensional space. Begin and Endpoint are identified by three coordinates.


If a value is entered instead of a reference to a spectrum, it will replace all entries of the spectrum (in case of A-weighted calculations, it will also replace the column for the weighted levels).


Drefl and Dr2 are supplements for multiple reflection defined in the guidelines RLS-90 and SCHALL 03. This value is to be entered into the list of traffic sources manually. Both guidelines suggest for a gorge a value of 4*h/w with the gorge depth h and the width w.
