EASE Evac v2.0.10


The new version EASE Evac 2 is a paid upgrade and includes the following new major features:

  • Updated STI calculation
    • Speech signal spectrum according to the 5th edition of IEC 60268-16. The setting is also shown in the report.
    • STI masking corrections according to the 5th edition of IEC 60268-16. 
  • Upgraded report
    • A dialog window allows selecting different options. Various tables can be disabled or enabled via this configuration window, as well up to 5 additional mappings can be added to report.
    • A progress bar indicates how many rooms have already been processed.
    • The report shows for each room several geometrical quantities including surface area, volume and dimensions.
    • Volume and surface area including objects are indicated as net volume and net surface area.
    • In the distribution data table the report shows the min and max values for the distribution statistics.
    • Surface materials information is added to the report 
    • When generating a report one can optionally add a table with all objects.
    • Cumulative distribution results are shown in the distribution section of the report.
  • Crest factor settings for constant-voltage networks
    • Allows switching between Sine, Speech (-9 dB) and Music (-15 dB) drive levels. 
    • Speaker power consumption is derated accordingly.
    • Line loss and additional headroom estimated at 2 dB (60%) total which are added to the power consumption.
  • Cumulative distribution and results at thresholds for all mapping quantities
    • For SPL, SNR, STI and CIS, the percentage area for the minimally achieved values is shown.
    • For Alcons, the percentage area for the maximally achieved values is shown.
  • Measurement tool in Top view provides distance, time of flight, X- and Y-offset for two selected points.
  • System definitions can now be selected from a tree drop-down, which has subfolders according to the loudspeaker brands/manufacturers.
  • Configure layout map by independent origin and scaling.
  • STI class width: added 0.05 selection to distribution graph
    • Extended class widths of all quantities to include 0.4/0.04 and 0.5/0.05 versions.
  • Added 4 dB and 5 dB widths to Relative Mapping of Direct SPL
    • Extended width choices for all result quantities.
  • Front View and Side View now show the horizontal dimensions of the sections.
  • Improvements to material assignment
    • Material areas in the Surfaces window can be copied, cut, and pasted.
    • Furthermore, inserting a new vertex assigns the previous material to both new walls.
  • Allow deactivating a receiver in the Frequency Response view
    • In the frequency response view, one can now right click on a receiver in the legend in order to deactivate it and hide its curve in the diagram.
  • Added NCB noise curves
  • Added RNC noise curves
  • Updated PNC and NC noise files
  • Added menu link to loudspeaker database on AFMG website


  • Fixed multi-thread problems when generating the report. This would occasionally cause an exception message that an object was already in use.
  • Fixed exception in the report generation that used to occur when a room has no speakers or only muted speakers.
  • Fixed sporadeous mapping graphic issue
  • Fixed sporadeous increase of line width for various graphs
  • Maximum values for Noise Levels were implemented
