Environmental noise computer modeling in CadnaA

To calculate environmental noise levels over large sites with complex terrain and noise environments, such as mechanical equipment, generators, industrial, and traffic noise sources, it is sensible to implement an acoustic model as a part of the evaluation. This presentation includes a review of the CadnaA Noise Prediction Software from DataKustik and how it can be used to help visualize the noise environment of a site or onto a building façade. We will discuss field measurements of existing sites, sound power data of noise sources, checking the model for accuracy, engineering assumptions, and common breaking points for inaccuracies in CadnaA.
