Acoustic screens and acoustic covers about noisemodelling HOT 4 OPEN

This coefficient is influent only if there are some reflections on the wall. Is this the case ?

Furthermore, I was wondering if we can put acoustic covers on the roads for example. Can we do that ? And if we can, how do we do that ?
This is the PVMT attribute in the ROADS table (see documentation)

When you mean that this coefficient is influent only if there are some reflexions on the wall, you mean I need to change the "order of relexion" ? But the default value is 1, so shouldn't it be working anyway ?

For acoustic covers I didn't mean the ground cover, but really acoustic covers. They are over the roads, this is not tunnels but really acoustic covers. You can see an example here :

And do you know more about acoustic semi-covers, how do we modelize them ? Acoustic semi-covers are just like acoustic covers but there is only one part of the roads that is concerned. Here is an example of acoustic semi-covers :

Hello,

Did you have the time to look at my question ?
I thank you in advance.

Yes, I am afraid nobody answers fastly because it is not only "NoiseModelling question"... :) Maybe, you can read the CNOSSOS-EU document to better understand how the propagation is modeled in NoiseModelling/CadnaA/Soundplan, etc.

I am sorry about this answer but this is the best we can do. If you have any question about the use of NoiseModelling, you should have faster ones ;) and we will be happy to answer.

Kind regards.
