Changes in iNoise 2024 compared to iNoise 2023.02

New and improved functionality

  • New CNOSSOS-EU method (add-on option) for Pro and Company licenses
    • For modelling roads, railways and industry according to the CNOSSOS-EU method.
    • Including catalogues for defining the emission of road vehicles, road surfaces, rail vehicles and rail tracks.
    • EU Population Exposure menu option. For counting the number of noise exposed people and dwellings according to the CNOSSOS-EU method
    • EU Noise Exposed Area menu option: For determination of the noise exposed area according to the CNOSSOS-EU method
  • New Analyst method for Pro and Company licences
    • For creating Analyst models for interpolating and cumulating noise contours based on grid results and confronting noise contours with demographic information
    • including Analyse contours menu option for confronting the calculated noise contour of the model with demographic information
  • New options for a Company license
    • Tile Model and Import Tiles menu options. For calculating large scale city noise maps
  • Background maps: Support of the Restfull protocol for WMS and WMTS services
  • Calibration of bitmaps: Calibration option 3 (with known GPS coordinates) now always uses the EPSG code of the model.
  • Export to Google Earth: The export option now always uses the EPSG code of the model.

Fixed issues

  • Line sources: When using the Lp-Lw option for line sources the calculated sound power is now automatically set to Lw/m
  • When selecting 1 single item on the model a maximum of 512 points are shown as marked points. In previous versions of iNoise all points of the item were shown as marked points which could generate a redraw of the model causing an endless loop.
