Calculation of NR and NC noise rating curves according to VDI 2081-1. Output for each receiver or as spatially averaged level spectra (in menu Options).
When aborting a calculation with the particle method, the results of the last iteration can now be kept (default = activated)
Calculating the workplace level for source groups now taking into account the floor as fully reflective (previously: actual absorption of the room's boundary surface)
Configuration of calculation: „Generate particles per octave“ now activated by default
Calculation of standard deviations (incl. number of points) in the table "Spatially averaged reverberation times (receivers)"
CadnaR Objects
All point and polygon objects: Object snap when moving / creating polygon points while pressing the ALT key
Receiver: New diagram Level spectrum for displaying the sound level spectrum incl. NR and NC noise weighting curves
Receiver chain: optional specification to use rounded values of L_p,A,S,4m and D_2,S for calculation of "Propagation class" and display in dialog
Bugfix, object Box-Type Source: Corrected conversion to LwA when using LwA'' and non-emitting surfaces
Receiver: New attributes S_NC and S_NR to show the single number value according to noise weighting curves of VDI 2081-1.
Further New Features
New language: Italian
Variants: Double click on a variant in the listbox activates / deactivates it.
Display of error bars in the diagram "Spatially averaged reverberation times" (receivers & grid)
Adjustment of the line width in the diagrams via the corresponding menu item. Fine adjustment via CTRL and +/-
Definition of a prototype file, which is loaded at every start of CadnaR
New toolbar icon for accessing "Spatially averaged reverberation times (receivers)". Multiple functionality via pressing CTRL and SHIFT for direct access to table and variant comparison.
Miscellaneous
Consistency Check for all receiver chains: Check if height of chain points are equal to source height.
Consistency Check: Warning at calculation of “receiver is workplace at source“ with LpA for a single source, if 0. order is not calculated with image sources.
