CadnaA 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, of a new road or railway scheme, or an airport, 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 communicates perfectly with other Windows applications like word processors, spreadsheet calculators, CAD software and GIS-databases.
CadnaA offers extremely powerful and extensive features for 3D visualization. With just one mouse click, any graphic view of the project can be generated. Dynamic 3D allows in real-time to drive through or even fly over your project model, e.g. a city or a large industrial plant, where buildings can be displayed with great realism thanks to textures. It is possible to stop anytime, look around and - by using mouse and arrow keys - continue moving in any direction. A video in AVI format can be created of every tour through the project model.
A mistake inside a 3D model (wrong height of a building), CadnaA allows to click directly on an object in the 3D view. The result can be viewed immediately on your screen. This allows comfortable check and alteration of the model.
CadnaA allows to handle projects of any size. There are practically no limits set by the software regarding number of objects (sources, buildings, contour lines, receiver points etc.). A large refinery with thousands of sources is just as easily assessed as cities or entire regions with numerous buildings and complex ground model. All project data are stored very conveniently in one file also including all project variants. This also allows very easy administration of different scenarios.
The only limitation for large projects is due to hardware memory. To break this one, CadnaA offers powerful features (PCSP technology for distributed calculation) and extensions (Option CALC: Networked distributed calculation). In fact with CadnaA you can handle projects of any size.
CadnaA offers very powerful features for the manipulation and representation of objects. Most actions need only one or a few mouse clicks to be performed. Some effective features are for example:
With CadnaA noise maps can be combined using an extremely flexible strategy. With the command "grid arithmetic" any user defined expression with complete noise maps as operands is evaluated and produces a new map. For example, a road noise map r1 and a train noise map r2 used with the formula r1++r2 produces a new map with the noise levels of road and railway added up energetically.
CadnaA offers already numerous powerful features. But with the following extensions you can even increase the range of features to get your work organized in a more efficient way or to enter new fields of application.
With these new functionalities, CadnaA becomes the most complete solution available in the noise prediction software market for airport noise assessment.
