Calculation

SonRoad18: Reflection condition

When using the calculation method SonRoad18 (2018, 2021 and 2024), the reflection condition of CNOSSOS was previously applied. This has been corrected, and the reflection condition according to ISO 9613-2 (1996 and 2024) is now used.

  • When clicking the calculator button in the toolbar with two or more variants active, the dialog for selecting the variants to be calculated is shown. This now matches the same behavior as when calculating the grid.
  • IoA Good Practice Guide: The correction for concave ground profile is only applied if the ray is not screened (Abar = 0).
  • New attribute SONR_VERS for sonRoad18 to set calculation acc. to version 2018, 2021 or 2024.

Bugfix

  • Bug fix for accessing files in the directory C:\Users\\AppData\Local\Datakustik (e.g. ini file, global library) when using a Windows username containing special characters or umlauts.
  • Lua: Reading access to the attribute MARK (acitvation) always returned 0 instead of "+", "-" or "" (empty string).
  • Coordinate transformation using EPSG 25833: In case x-coordinates are in the format 33xxxxxx (leading 33), the prefix is automatically removed for transformation.
  • PlotDesigner: When using the 3D cell, it could happen that the displayed image was shown twice.
