SoundPLANnoise Frequently Asked Questions

Question number FAQ-1079

Are you currently using the so-called "area-wide evaluation of road noise" method, which is being implemented as part of the "Assessment of Achievement of Environmental Standards" initiative led by the Ministry of the Environment?

We apologize, but this method is not supported. However, we can perform calculations based on the ASJ RTN-Model 2018, so it is possible to perform calculations that do not deviate from the purpose of area-wide evaluation. In areas with many undulations or special road sections, which are often challenging in area-wide evaluation, SoundPLANnoise can flexibly create terrain and perform calculations.
