New in Predictor V2022.1 is the EU Noise Exposed Area calculation option according to CNOSSOS-EU. This option determines the result of calculation points in buildings based on the lowest level outside the buildings and calculates the exposed area using Voronoi polygons. Voronoi polygons allow the combination of grids and contour points. In this way the user can create more densely spaced calculation points close to sources, while further away the spacing can be set larger. This saves calculation time and provides accurate results where you need it. Further improvements for CNOSSOS calculations include the use of extra wavelengths 2000 mm, 1600 mm and 1250 mm for railway emission and an increased accuracy for Gradients of roads. All modifications are described in the readme file. Version V2022.1 can be used with a valid V2022 license.
