Noise3D online working with SketchUp® and Google Earth© is an outstanding toolset for noise calculation and mapping. Google Earth providing a user chosen Terrain into SketchUp and noise3D online allowing acoustic modeling are a perfect setup for providing professional planning results for noise control engineering.
The concept works as follows:
- SketchUp allows you to import a terrain from Google Earth which will become
your floor plan for acoustic modeling.
- Noise3D online leverages the 3D capabilities of Sketchup and enables users
to create sophisticated acoustic models âplacedâ on Google Earth
- When the noise calculation results have been calculated noise3D online
allows you to export the acoustic model and the noise map into Google Earth
on your PC.
- The compelling results will convince your customers and any interested
- The model will not be loaded into public Google Earth.
1. Import to SketchUp and noise3D online
If you intend to start your project with a floor plan from Google Earth please
launch SketchUp and enable the Google tools
SketchUp -> View -> Toolbars -> choose Google
Klick the Google Add Location icon which will present a new SketchUp window from
which a Google Earth location can be chosen, zoom in and -> Select
Region adjust as required and -> Grab.
The picture grabbed will become your floor plan for your project. Please save
the project and proceed with acoustic modeling in SketchUP and noise3D online.
For the time being it may be appropriate to leave the Terrain toggled off (see
Google button Toggle Terrain), since noise3D version 2.0.2 does not yet fully
support a 3D Terrain (scheduled for launch with version 2.1).
2. Export to Google Earth
When you have completed the modelling in noise3D online and you want to show the
results in Google Earth then you can review it using the -> Preview
Model in Google Earth icon.
Eventually, when you want to present the results in Google Earth please proceed
as follows. In SketchUp export the model:
SketchUp: File -> Export -> 3D Model
and chose export type Google Earth File (*.kmz). A PC directory and a file name
can be chosen for the transfer of data, then click Export.
(Note: Before exporting please make sure you have still toggled
off the terrain. Noise3D online does not yet support contour lines, however, the
noise map is always horizontal. With Google Earth surface being at different
heights it may be required to elevate the noise map above ground. This is
possible with a new plugin function “drop at …”. We typically elevate noise
maps a few meters above ground so that they become fully visible. Where you have
steep slopes in your terrain it may be required to elevate the noise map even a
Now open Google Earth and proceed with the import:
and select the file which has just been stored in the previous step.
Google Earth will now show the noise3D online import as âCreated with
SketchUpâ (menu left side) and you will find model and noise map properly laid
down on Google Earth. In case you want to further refine the acoustic model
please use the Google -> Photo Textures icon to find and apply photographic textures from Street View to walls in your model.
