Noise Modelling

CadnaA - The complete software package for the Prediction and management of Environmental Noise

Some key features of CadnaA:

  • International and UK standards implemented. CRTN for road, CRN for railway, ISO9613 for industry and BS5228 for construction noise.
  • No software related constraints on size of the model.
  • Various powerful features for automatic correction of faulty or inconsistent import data (for example: command "Close Polygons" to generate buildings, fitting of objects to the terrain model, or fitting the  terrain model to the objejcts)
  • Very fast calculation speed - NEW version 3.6 - automatic handling of multi thread and dual processor PC's
  • Fully automatic, software-controlled parallel processing with an arbitrary number of computers in a network (For example using all of your office computers at night.)
  • Calculation of the facade sound levels for all buildings of a town (selectable: all levels, the highest or the lowest only), noise statistics strictly according to the EU-directive of environmental noise (without additional data collection)
  • Coloured 3-dimensional view of the terrain and of the building facades according to the noise levels. NEW version 3.6 - Bitmaps and 3D photographs are viewed in 3D.
  • In real-time calculated fly-throughs across your model - stopping, presenting and editing data possible at any time (i.e. editing in 3D-view!)
  • Additional modules and programs communicating with CadnaA: the expert system SET to generate noise emission data. APL for air pollution. XL for cities.
  • Calculation of the pass-by level for cars, trucks or trains with acoustical replay via loudspeaker (Auralization)
  • automatic generation of noise maps (in bitmap-format), ready to be transferred to Internet-sites, inactive retrieval of level informations on the spot with zoom-function    (see http://www.noiseRus.com)

Bastian - The Building Acoustics Planning Software
BASTIAN is the software for the calculation of airborne and impact sound transmission in buildings and of airborne sound transmission of outdoor sound.

The calculations within BASTIAN are based on the European standard series EN 12354, parts 1, 2 and 3, which will become part of the national standards in each member state of the European Community (EC) and will therefore form the common international basis for the prediction of sound insulation of buildings in the near future.

The calculation of sound transmission with BASTIAN takes all sound transmitting elements and systems into consideration which are relevant for the individual room-to-room situation. In addition to the separating and the four flanking elements, doors and windows can be inserted into the separating construction. Further, flanking elements or even airborne sound transmitting systems, such as ventilation and cable ducts, can be added.

All calculation results for airborne sound transmission between rooms and from the outside can be rendered audible with the optional program extension BASTIAN-Auralization for various interior and exterior sound sources and for different kinds of receiving rooms.
