Release date: January 29, 2018

The download link includes an unregistered license for iNoise 2018 Free. Pro and Enterprise users will automatically receive a new license to work with iNoise 2018. Please note: current users of iNoise 2017 Free need to register again for iNoise 2018.

Changes in iNoise 2018.01 compared to iNoise 2018

New functionality

  • 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.

Fixed problems

  • The scaling & position option for calibrating bitmaps did not function correctly.

Changes in iNoise 2018 compared to iNoise 2017

New functionality

  • 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 ‘’ and ‘’ 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.

Improved functionality

  • 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.

Minimum system requirements for using iNoise
