Changes in iNoise 2018.2 compared to iNoise 2018.01
New and improved functionality
- New Calculation setting for Valley correction (for wind turbines)
This allows automated calculation of the valley correction for Wind Turbines according to IOA GPG TO ETSU-R-97.
- New calcualtion option for Area sources: ‘Neglect screening and reflection of objects on area source’ .
- The menu option ‘View | Zoom | Synchronized zoom’ for multiple models now stays active until a new model is opened or an active model is closed.
- The menu option ‘Edit | Batch Create Items | Receivers at facades’ now supports the 3 methods (1, 2a and 2b) defined in the CNOSSOS method.
- Operators ‘Equals’, ‘Contains’, ‘Starts with’ and ‘Ends with’ added to menu option ‘Edit | Search and Select’. This allows searching on partual text values in the name or description of items.
- Double click in pan mode now zooms in a factor of 2. This for better support of zooming with a touchpad.
- When using thematic display for items, per default the option ‘Draw remaining items using standard color settings’ is enabled.
- The Stopsign icon in the Open model dialogue has been replaced by an open folder icon.
- Menu option “Results | Result Labels” moved to menu option “Results | Contours and Result Labels”
- Menu option ‘Results | No Results’ renamed to ‘Results | Hide Contours and Result Labels”
- Help tip ‘Click header column to sort’ added when hovering the mouse above the column headers of the Table of Results and the List of Items’. Also a no-sort option added.
- The paths in the SHP file when saving the cross section to SHP in the test calculation option, now only include the paths used for the calculation. The SHP file can then be imported as DIV lines and shown in the 3D View. This enables showing in 3D the exact rubber band paths for the vertical and the horinzontal detours.
- Updated helpfile on Viewing octave or 1/3 octave results, Concawe meteo, emitting facades
- For moving sources the Cb value could not become negative. This resulted in an incorrect calculated value. Moving sources with a high flow and/or large distance between the pointsources and/or low average speed can now have a negative Cb value.
- In some cases the 3D directivity for sources was not calculated correctly.
- In some cases an error was shown when starting a calculation with emitting facades that were created using the menu option ‘Edit | Batch Create Items | Paralel items …’, or with the right mouse menu option ‘Create Paralel Items’.
- In some cases an error message was shown when using the Copy to Clipboard option in the Table of Control.
Changes in iNoise 2018.01 compared to iNoise 2018
- QA document ‘Declaration of conformity to ISO 9613 and ISO 17534-3.pdf’
After installing iNoise 2018.01 the QA document ‘Declaration of conformity to ISO 9613 and ISO 17534-3.pdf’ is located in the ‘C:\Program Files\DGMR\iNoise 2018\Doc’ folder.
- Help file
Some additions to the help text.
- The scaling & position option for calibrating bitmaps did not function correctly.
Changes in iNoise 2018 compared to iNoise 2017
- Calibrate option for bitmaps (in View | Background menu)
Quick and easy scaling and positioning option for bitmap background maps by entering a line of known length or 2 points of known coordinates.
- Sound pressure (Lp) to sound power (Lw) option
Point, Line and Moving Sources now have the option to calculate the Lw from a measured Lp value at a certain distance of the source.
- SourceDB option (in Tools | SourceDB menu)
SourceDB is a separate software that enables storing, searching and sorting your own sound power data, as an extension of the European IMAGINE database. SourceDB supports 1/3 octaves, a script language to define parameters and formulas to calcalate the Lw and adding pictures to the sources. A sound power level in SourceDB can be easily copied and pasted in a source of an iNoise model.
- Default sound power levels for road traffic
The default sound power catalogues ‘SourcePower_Octave.cat’ and ‘SourcePower_Terts.cat’ now include sound powers for light, medium and heavy vehicles driving 50, 80 or 100 km/hr. The sound powers are taken from the CNOSSOS-EU method. In combination with the moving source item this makes it more convenient to calculate road traffic noise according to the ISO 9613 propagation.
- Web Map Tiled Services (WMTS) as background maps (in View | Background menu)
WMTS is a faster service compared to WMS.
- Edit always
Modification of a model is now always possible, also when the result labels and/or contours are shown. After a modification that might change the calculated results, the result labels and/or contours are automatically taken off the model. This does not apply to final models and models that are opened in read-only mode.
- Display of the mean height above ground during test calculation
When using the alternative method for the ground attenuation the mean height above ground is now also displayed in the test output. This is specifically useful when determining a Valley Correction for wind turbines according to legislation in the UK.
- Default meteo setting for new models is now ‘No Meteo’
Most countries use the ‘No meteo’ setting when comparing against limits
- Default result storage for receivers is now ‘Source results’
Now per default the calculated results per octave or 1/3 octave can be displayed for single receivers in the table of results.
