CadnaA

CadnaA (Computer Aided Noise Abatement) is the software for the calculation and presentation, assessment and prediction of noise exposure and air pollutant impact. Whether your objective is to study the noise immission of an industrial plant, of a mall including a parking lot, of a new road or
railway scheme, or even of entire towns and urbanized areas: CadnaA is designed to handle all these tasks.

CALCULATION

CadnaA is a transparent and easy to use platform for everything from simple checks up to extremely complex and scientific investigations. The clear separation of the 3D-model in its natural environment and the applied calculation method offers flexibility unique in this area. It is even possible to use the same model when noise levels are calculated based on different national standards without any need to modify the model.

• Calculation with about 30 standards and guidelines
• For any number of fixed receiver points, calculation and storage of all source related partial levels – therefore detailed analysis is possible without recalculation
• Levels at grid points (noise maps) can be added, subtracted and processed with any user defined function
• Parallel processing with any number of computers to reduce calculation time within large scale noise
  maps (hundreds or even thousands of km²) with PCSP (Program Controlled Segmented Processing)
• Multi-threading support – parallel use of all processors on a multicore PC with a single license
• Levels on grid enveloping building facades to show buildings coloured according to the sound pressure levels
• Up to 4 parallel evaluation parameters – e.g. L(day), L(night), L(dn), L(evening), L(den)
