General Information

This chapter is about radiation in industrial sources like buildings and chimneys. The information from the Basics chapter is used to create more complex industrial sources.


The chapter starts with an illustration of different possibilities of building creation. It is shown how radiating elements like windows are added.
Directivity can be added to sound sources. This is shown for exposed point sources.
The last section discusses the modeling of radiating chimneys in CadnaA. Some settings have to be done to get a realistic model.


The chapter Basics is the only precondition for the work with industry sources.

Further Information

Complex industrial sources like radiating buildings are not modeled in other chapters. The chapter Noise Mapping provides further applications of grids like those used in this section.
