3D buildings about noisemodelling HOT 8 CLOSED

I am not sure how to technically achieve those geometries but I have to point out that trees should not be modeled that way.
Leaves and branches can be considered acoustically transparent and the impact of trunks is often neglected in most simulations.
You can evaluate the (very small) impact on vegetation on façade absorptions for exemple but not for "masking" purposes.

if these are not trees but concrete blocks you can ignore my previous comment :)

Thanks for the comment! I actually want to understand if is it possible for the noise modeling tool to recognize that my building structure is off the ground (e.g. roof).

I believe that everything is projected down to ground, so no I believe a floating roof can not exist

Understood, thank you so much!

Hi Noise Modelling Team, I am part of a research group from Singapore Nanyang Technological University. We are interested in using this software tool to analyze noise in an urban area. We are currently using the import_osm block in the WPS builder to generate buildings. However, we realized that buildings with complex shapes are recognized differently. For instance, the marina bay sands buildings, where the observatory deck was supposed to be at the top of the buildings:

Buildings generated by Noise Modelling, visualized in QGIS: (observation deck projected down to ground)

From what I note from the documentation, Noise Modelling is able to analyze complex roof shapes:

We hope to get some advice on what type of information is required for Noise Modelling in order to detect complex shapes or if there are any other software applications that we can export the data from to import into Noise Modelling for better representations. Thank you!

I believe this is the typical shape (a hole in a building, typically any ark building) that is not supported by the CNOSSOS model (and therefore in NoiseModelling).

I am not familiar enough with the variety of acoustic propagation models to recommend any other software but the Harmonoise model could be worth looking at. It is known to be better than CNOSSOS-EU in many aspects, but I'm not sure about this particular issue.

Ok, thank you!
