Changes in iNoise 2020 compared to iNoise 2019.1

New and improved functionality

  • Input of A, C and Z weighted sound power levels
    This enables the input of A, Z and C weighted sound power levels. An additional A-weighting is not needed anymore.
  • New Font Settings option in Display Options. Font, color and in frame for labels of Items and Results
  • Lmax option for ISO 9613 models in Table of Results
    This enables showing the LAeq as well as the Lmax value of e.g. moving sources.
  • PDF support as Background Map
  • Increased performance for large models. Faster import, faster calculation of the terrain model and faster creation of the 3D view
  • Export to KML (Google Earth) now based on Display Options. Now the user can influence the size of the KML file by for instance de-selecting the display of grid points
  • In the option Lp to Lw for point and line sources the entered values are kept in memory as long as the item attribute form is open
  • ‘Delete’ option in mouse menu
  • In ‘File | Export | Batch Export Point Results’ the type of Receiver can now be selected
  • X and Y coordinates are added to the Table of Results for both Receivers and Sources. For line and Area sources the coordinate of the first node is shown
  • New ‘Catalogues | General’ menu option with internal editor
    All *.cat files (catalogue files) such as Sound power levels, Isolation materials, Reductions and Wind profiles can now be edited including copy/past support to/from Excel
  • In the menu option ‘Results | Contours and Results Labels’ labels for results and control values of the background model can be selected
  • The menu option ‘Edit | Batch Create Items | Receivers at Facades’ now supports a distance between the receiver points for CNOSSOS-EU case 2a
  • The text ‘Source results’ on the Calculations Settings has been changed in ‘Source and Octave results’.

Fixed problems

  • ISO 9613.1/2, ISO 9613.1/2 (1/3 Octaves) methods: Area sources now automatically generate at least 1 point source, also when using x and y steps that are larger then the area dimensions
  • Menu option ‘Edit | Batch Create Items | Create Receivers at Façade’ modified:
    Default height definition is now Relative (was Absolute)
  • Zoom to selection did not work when the selection is only 1 pixel
  • When using the ‘File | Import | CAD file’ option groups were always created despite unchecking the Group checkbox.
