CadnaA – Outdoor Noise

CadnaA is a world-leading, state-of-the-art software for modeling, calculation, and assessment of environmental noise. It can be used efficiently at any scale, starting with a few single receivers in a neighborhood up to noise-mapping projects of entire countries. This works for various source types in the fields of road, railway, aircraft, and industrial noise.

Whether your objective is to study the noise immission of an industrial plant, 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.





Due to its numerous features CadnaA is the most powerful noise calculation and noise mapping software available. Every feature is and will be designed only to ensure that you can handle your projects in the most convenient and efficient way. The easy-to-use interface with self-explanatory symbols and clear command structure always helps you to keep an overview even with these numbers of features and possibilities. CadnaA has a multi-lingual user interface and comes with comprehensive documentation. CadnaA is copy protected by a local USB dongle. A server dongle for network licenses is available as an option.

The range of powerful features includes:

Grid noise maps (horizontal + vertical)
Building noise maps
Dynamic noise maps
Grid arithmetics
Distributed calculation (PCSP)
Multithreading
GIS integration
Web export
Dynamic-3D
Plot/Report designer

Numerous import and export interfaces such as:
AutoCAD DXF
ArcView Shape
MapInfo,
CityGML,
ASCII
QSI, etc.

General CadnaA Configurations

To server customers’ needs in an individual and convenient way, there are three different product versions available:

CadnaA Standard – allows for calculation of noise from industrial, road and railway sources. This configuration comes with all calculation standards for these noise types.

CadnaA Basic – allows for calculation of noise from industrial, road and railway sources. This configuration comes with one calculation standard of choice for each of the noise types. Additional standards may be subsequently added for additional cost.

CadnaA Modular – this package is tailored for customers that don’t have the need to model all industrial, road and railway sources. With this configuration, for instance, customers can choose the Module Industry to model industrial noise sources only. Each noise type comes with one calculation standard of choice. More standards may be subsequently added for additional cost.

CadnaA Modular Light – this package is similar to CadnaA Modular with the number of sources limited to 30 for roads, railway, area sources, and line sources each and up to 50 for point sources.

Additional Options

Option BMP: Bitmap and other Interfaces
Import various bitmap formats. This option includes direct access to Google Earth (Import/Export)
With option BMP bitmap-files can be imported in various formats to serve as background pictures. The most common application is importing scanned maps used as a template for entering sound sources, receiver points and other objects. Furthermore, digital or digitized photographs (orthophotos) in TIFF or JPEG format can be imported.

Option BPL: Backtracking of Sound Power LevelsOption SET: Sound Emission and Transmission
With the expert system Option SET sound power spectra can be automatically generated based on technical system parameters of a sound source (e.g. electric power in kW, volume flow in m3/h, rotations in 1/min etc.). Thus a unique system capable of modeling various kinds of sound sources is achieved.

Option APL: Air Pollution
Calculate air pollution for more than 50 pollutants for industrial and road sources

Option FLG: Aircraft Noise
Calculate noise propagation from aircrafts

Option FLG – Radar Tracks
Use radar tracks (Fanomos, Stanly, Topsonic) for aircraft noise calculations. Group assignment is done via ICAO code.

Option X: Extended Features
A feature-pack especially for noise mapping. It contains the features Object-Scan, Population Density, Monetary Evaluation, Map of Conflicts, Close Polygons Automatically, Delete Height Points

Option L: Large Scale Projects
Calculate with an unlimited number of screening objects.

Option XL: Noise Mapping
Combination of options X and L

Option MITHRA
Assure compatibility of calculation results with the French program MITHRA.

Option 64bit: 64-bit Version
Use CadnaA (incl. all further extensions) with 64bit address length. Handle large projects with one single file. 64GB of RAM can be addressed; a 64bit operating system is required.
