Configuration

In developing CadnaA, it was, and continues to be, our goal to give the professional user the desired freedom of choice and control while relieving those only interested in overall results from having to master all the available options. This complexity and flexibility of CadnaA is particularly evident when large stocks of data have been entered which are then to be processed under the Calculation|Configuration menu.

To meet the requirements for the calculation according to EC-Directive on Environmental Noise CadnaA offers a flexible concept for defining and calculating evaluation parameters (see Evaluation Parameters Tab). This concept enables to select from a number of pre-defined evaluation parameters (levels for single or combined time intervals) and some more specific parameters (such as the uncertainty Sigma). Furthermore, you may define your own evaluation parameters using formulas.

In CadnaA up to four evaluation parameters can be calculated simultaneously, either for single receiver points or in a receiver grid (in addition to the ground).

The dialog Calculation|Configuration serves to specify all settings required for the calculation, and, quite conveniently, to save these settings with the calculated project file. There are various tabs for groups of options within this dialog. Click the tab for the desired group to specify and select the options.
