Is the program UL Listed or FM Approved for acceptance as proof of the intelligibility of a voice evacuation system?

EASE Evac is not listed by any regulatory or standards agencies for proof of intelligibility. It is intended to be a software tool to help the MNS designer predict the speech intelligibility of a sound system design in a particular space given the surface treatments of the room boundaries.

I draw my EASE room in SketchUp. If I import it in EASE, I do not see all layer names as proposals for EASE materials. What did I do wrong?

The SketchUp import process uses two possible sources for the EASE material of an EASE face.

  1. If the SketchUp face has a SketchUp material attached, then this is the preferred proposal for the EASE material.
  2. If the SketchUp face has the Default material attached, then the layer name is used as a proposal for the EASE material.

Example 1:

How do I create a new EASE 4.x Project from a Sketchup model?

The first step is to keep in mind the usual requirements of an EASE 4.x project. Users creating a model in SketchUp should be aware of the conventions adopted by EASE. For instance, the proper orientation of Faces, and the correct application of Two-Fold Faces, among others.

Here you will find some hints for the construction process in order to successfully import a room into EASE 4.x.

The following Tutorial-Room can be imported and will pass the Check Data process in EASE 4.x without errors:

Peek Frequency Response with Probe

I am really annoyed by the fact that when I am peeking around in the Mapping or Eyes module and use the Probe function to look closer at the frequency response it always switches back to the reflectogram view.

To solve that, go to Probe Options via F9 or File/Options and select "Previous Graph" under "Default Graph" on the "General" page.
