Option VIS: Visualisation

Option VIS adds visualisation features to get a deeper understanding of the results and for presentation purposes.

Visualisation of the calculation: calculation rays in 3D, particle animation.
Import of textured 3D-Objects for presentation purposes.
Usage of high-resolution bitmaps (e.g. as a layout plan).
Vertical grid and 3D grid.

Option ORG: Project Organisation

With Option ORG, the organisation 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 auralisation 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 optimisation 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 customised 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 visualisations are not necessary.

Calculation of energetic impulse responses and echograms at receivers.
Calculation of reverberation time (T20, T30).
Grid calculation for T20 and T30.

CadnaR.Scan App - Room Capture with LiDAR & iPhone

With CadnaR.scan, you can quickly create a digital room model of your surroundings. Quickly create simplified 3D scans of rooms and entire floors, including walls, built-in wall elements, and objects in the room. The model can then be imported into CadnaR for further acoustical processing.

Industrial Acoustics

Industry acoustics comprise a wide range of applications which are succesfully managed by CadnaR. From the simple determination of the noise impact at work spaces to the full assessment and improvement of a industrial hall, CadnaR has been especially designed for the particular requirements of any project. CadnaR includes the following industry-specific features:
