Noise Prediction for Industry and Wind Turbines
Frequently Asked Questions (FAQ)
What are the minimum system requirements for using iNoise?
The minimum system requirements for using iNoise are:
- dual core processor, such as Intel Core i3, or AMD Phenom X2
- 2 Gb RAM
- With a Pro or Enterprise license (> 2 cores), a quad-core processor and more RAM memory are recommended
- Operating system: Microsoft Windows 7/8/10 (x64)
- 500 Mb free disk space to install the software
- Additional 100 Mb free disk space for each iNoise project. Larger iNoise projects can take more than 1 Gb of disk space
- OpenGL support for 3D view
- Printer: MS Windows printer
- Internet access to download the software and to check for updates.
Why does the software still run in demo after I installed a valid license?
Copy your license files DGMR.LIC and DGMR.LICX to the iNoise program folder (usually C:\Program Files\DGMR\iNoise 2017). In case the software still runs in demo, this is probably caused by the secured Windows environment. Windows won’t allow files to be copied directly from an email message to a secure folder, such as the “Program files” folder. To copy the license files from an email message, you should copy them first to a temporary location, for instance your desktop, and from there you can copy them to the iNoise program folder.
How does Georeference work?
Georeference is a tool to grab images from Google Earth, which can be used as a background map in iNoise. To grab images, you will first need to install Google Earth.
Please note: the current version of Google Earth is incompatible with Georeference. To use Georeference you will need to install an older version of Google Earth. We suggest you use V188.8.131.5206, which can be downloaded here:
After starting Georeference you select the correct coordinate system for your model, for instance:
|Coordinate system||Netherlands Stereographic coordinates|
|Reference system||RD/NAP (NL 2008 <±0.1m), Amersfoort, Bessel|
Google Earth can be started from within Georeference by using the [Start] button behind the option “Grab from Google Earth”. After Google Earth has started you’ll have to find the area from which you need an image. The “view” which is visible in Google Earth will be grabbed.
As soon as the correct view is visible, you need to switch back to Georeference and click the [Grab] button. Georeference will then ask for a filename and location to save the file, after which the view will be visible within Georeference.
Finally the button [Save as JGW] has to be clicked after which the background is ready to be used within iNoise. Two files were saved: the image file (extension JPG) and a text file containing the coordinates of the background image (extension JGW). The image can now be selected as a background within iNoise. The coordinates will be entered automatically.
