EASE Evac provides an intuitive tool for designing acoustic mass notification concepts in a room, hall or building complex. The 3D simulation software calculates the distribution of direct sound levels as well as total sound levels, the signal-to-noise ratio (SNR) and speech intelligibility (STI, ALCons, CIS).
All floor plan room geometry must be traced from imported drawings or image files using the drawing tools in EASE Evac. The import process does not translate directly to the room geometry.
Supported formats are AutoCAD DXF, Google Sketchup and various image files such as PNG.
New materials files can be created with the EASE software. It includes a material database editor that is capable of editing and saving surface material files.
At the moment, EASE Evac supports typical ceiling loudspeakers and regular point source loudspeakers for wall mounting. Line arrays and steered column speakers are not yet supported.
In order to use loudspeaker data in EASE Evac, you need to have this available as a .GLL file. These files are either already included in the AFMG loudspeaker database for EASE Evac or, in many cases, can be downloaded from the respective manufacturer’s website.
GLL files to be used in EASE Evac must be of type Loudspeaker. They must also have the property Rated Opening Angle defined. If this is not the case the program will show a warning e.g. when importing the system definition via the File menu of EASE Evac.
Adding your data to the EASE Evac loudspeaker database is free of charge. It requires collecting selected loudspeaker performance data and converting it in a binary format.
Acoustic, electronic and mechanical data of the sound source must be assembled in a single data file, the so-called GLL. This GLL file can also include your logo and company information.
It is not probable that local AHJs will approve EASE Evac predictions of intelligibility in lieu of measured performance. The software complements and improves the design process but cannot replace on-site validation.
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.
Microsoft’s Windows updates and upgrade apply changes which interfere with the checksums of User Keys for AFMG software.
Reason:
New User Files or Certificate installed without removing a previously installed license. This error can occur if not all previous settings of an earlier installation could be removed from your PC during the installation of the newer version.
To fix the problem please perform the following steps:
Not all GLL files are the same. Some AFMG® programs have specific requirements for a GLL in order that the program is permitted to use the GLL.
The chart below summarizes what types of GLLs can be used in each AFMG program.
