Options
CadnaR can be functionally expanded with a number of options*. Learn more about the available options below.
Some options need other options as a prerequisite for specific features. Please refer to the scope of performance document for more information.
Option CAL: calculation and handling
Option CAL increases the performance of CadnaR enormously by adding additional calculation methods and further features.
Additional calculation methods: VDI3760, diffuse field method, hybrid method (image sources + particles).
Further source types: line source, area source, box-type source.
Calculation and visualization of the voxel grid.
Usage of the receiver chains.
Plot Designer for printing customized layouts.
Automatic calibration of absorption and scattering coefficients to achieve user-defined target reverberation times.
Dosimeter function.
Batch calculation.
Option VIS: visualization
Option VIS adds visualization features to get a deeper understanding of the results and for presentation purposes.
Visualization of the calculation: calculation rays in 3D, particle animation.
Usage of high-resolution bitmaps (e.g. as a layout plan).
Import of textured 3D-Objects for presentation purposes.
Vertical grid and 3D grid.
Option ORG: project organization
With Option ORG, the organization and handling of projects of any size is massively improved.
Grouping of objects (Objectree).
Usage of variants.
Efficient handling and comparison of up to 16 scenarios in a single file.
Calculation of partial levels.
CUDA calculation.
Import of DWG and DXF files.
Option AUDIO
Option AUDIO is a must have extension for acoustics experts who need to calculate reverberation times, Speech Transmission Index (STI) and further parameters on top of the sound pressure levels.
Calculation and auralization of room acoustic and psychoacoustic parameters.
Calculation of energetic impulse responses and echograms.
Calculation of reverberation time (T10, T20, T30).
Calculation of the Speech Transmission Index (STI, STIPA).
Calculation of further parameters like e.g. Alcons, C60, D50, CIS and EDT.
Option OFFICE
Option OFFICE includes a selection of features from both options CAL and ORG for the handling, evaluation and optimization of offices and open plan offices. Usually to be combined with Option T (or Option AUDIO).
Calculation and evaluation of receiver chains.
Horizontal grid calculation (2D).
Import of DWG files.
Export of full reports in MS Excel and MS Word.
Grouping of objects (Objectree).
Plot Designer for printing customized layouts.
Option T
Option T adds on selected features of Option AUDIO for the calculation and representation of the reverberation time (T20, T30). CadnaR with Options OFFICE and T represents the cost-efficient solution for office and also industrial applications with limited size and complexity when visualizations are not necessary.
Calculation of energetic impulse responses and echograms at receivers.
Calculation of reverberation time (T20, T30).
Grid calculation for T20 and T30.
Option SET: sound emission and transmission
With the Option SET, sound power spectra for complex systems can be automatically generated based on technical system parameters of a sound source (e.g. electric power in kW, volume flow in m3/h, etc.).
Generation of frequency spectra of radiating sound power determined from the technical parameters of a sound source.
Modeling of complex facilities and devices with multiple sound sources and radiating surfaces, considering the transmission between parts.
Ready-to-use stablished pool of data of about 150 pre-defined sound source models (source descriptions).
Data pool can be easily extended by user-defined sound source models.
