Chapter 1 - Introduction

CadnaA is a software program for the calculation and the assessment of noise and air pollution. The program fulfills the requirements for professional experts.

The software calculates and predicts the noise immission in the neighborhood of:

  • commercial and industrial sites,
  • sports and leisure facilities,

and of traffic systems like

  • road and railways,
  • airports and landing strips, or
  • any other noisy facilities.

CadnaA is suitable for noise prediction in local studies as well as for detailed analyses of mapping noise scenarios in large cities. Powerful features include incredible screen displays, handling and output of graphical grids and the use of scanned bitmap plans. CadnaA enables automatic optimization of barriers and the automatic allocation of noise quota. Aircraft noise in the vicinity of airports, landing strips and related facilities can also be calculated with CadnaA.

The capabilities of CadnaA can be extended by the calculation, the assessment, and the presentation of air pollutants distribution.

The sound level during pass-by’s with time history and auralization of moving sources, the different 3D-views of your project when moving through, the PCSP (Program Controlled Segmented Processing) to accelerate calculation of large projects, the groups and the ObjectTree are just some highlights of CadnaA.
