Success Stories

Noise Mapping Austria
The strategic noise maps for all of Austria were calculated with CadnaA. more

You are here: Products > CadnaA > Modeling and Calculation > Presentation of Results > Auralization


The calculated levels are equivalent averaged levels related to certain time intervals (generally day and night). It is also possible to determine the time history of the instantaneous level if a car, a train or any other moving source passes. CadnaA uses the same exact calculation with the whole model for each position of the moving source.

 Time history of pass-by level for light traffic

With sound card and attached amplifier/loudspeaker the pass by noise is presented acoustically (auralization).
