Building Evaluation & Building Noise Map

The building evaluation in CadnaA enables the calculation of noise levels at façades of buildings due to noise impact from industry, roads and railway tracks. For the respective noise type the standard or guideline as specified in the configuration of calculation is applied. Based on the building noise map one can determine facade points meeting or exceeding a limiting sound level.

In this introduction a point source is used to explain the fundamental procedure and the most essential features. The calculation is carried out according to the standard ISO 9613 (1996).
