CadnaA (Computer Aided Noise Abatement) is the leading software for calculation, presentation, assessment and prediction of environmental noise. Whether your objective is to study the noise immission of an industrial plant, of a mart 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.

With more than 30 implemented standards and guidelines, powerful calculation algorithms, extensive tools for object handling, outstanding 3D visualization and the very user-friendly interface CadnaA is the perfect software to handle national and international noise calculation and noise mapping projects of any size.

CadnaA with extension Option APL also allows calculation, assessment and presentation of air pollutant distribution.

With its technical capabilities and its ease of use CadnaA represents state-of-the-art technology. CadnaA is developed in C/C++ and communicates perfectly with other Windows applications like word processors, spreadsheet calculators, CAD software and GIS-databases.

CadnaA includes a multi-lingual user interface and is successfully applied in more than 60 countries all over the world.

CadnaA offers numerous tools to set up your calculation model, to present the results and to communicate with related applications like spreadsheet programs, CAD software or GIS systems via import and export interfaces. All of these tools are designed to be as easy to use as possible. That´s why most of all actions need only one or a few mouse clicks to be performed.
The calculation of noise levels is always done accurate to the latest international standards and guidelines. Due to the implemented powerful acceleration techniques and refined algorithms CadnaA is by far the fastest noise prediction software on the market.
