Reinstall Room symmetry

Q: After I completed my project on a symmetrical base I had to modify it again. I released the symmetry to allow the new data to be entered. As a result of the calculations I found it necessary to include some more symmetrical walls. So I reinstalled the symmetry. My problem is, all of the faces and other items seem to appear twice. Is this a program bug?

What is Ease Room?

Help on Ease Room - Edit Project Data / Case Data / Cluster Data

Ease Room is a module of EASE 4.0/3.0 that allows you to insert and modify buildings (eg. rooms, studios, stadiums), loudspeaker cases, loudspeaker clusters, furniture (like chairs, tables) and room parts (like columns, balconys, windows) in a wireframe view.
As a basic module of Ease it is used in many different ways:

How do I fix “Face Mismatch or Hole in Room”

After clicking Check Data [F5], or attempting to Save Project Data [F6], I receive the following message:

"Face Mismatch or Hole in Room.
Use Check Holes to get detailed information."

What does this mean and how do I solve this problem?

This is a sign that your room model has geometry problems, the so-called “holes”. Holes are the result of violating one or more conventions of EASE and they need to be fixed before you can go on and perform simulations.
 

I am trying to save/open an EASE project on my network and get "Run-time error '75', Path/File access error". How do I fix this problem?

This error is the result of trying to save an EASE project to a network location that contains a double backslash ("\\") in the path name. To avoid the problem, please use "Map network drive" in Windows Explorer to first map the desired network folder as a hard drive on the local computer. The EASE project can then be saved to or opened from the mapped hard drive on the local computer.

Running EASE seems to be causing AutoCAD (from Autodesk) to want to run its installation routine. How do I correct this?

If running EASE always causes Autodesk AutoCAD (or a related product) to run its installation routine, this is most likely an indication that the installation of AutoCAD was somehow corrupted and needs to be repaired.  To correct this problem please go to the Windows Control Panel, choose Programs and Features, then click on Autodesk AutoCAD (or the related product) to perform a repair or reinstall.

AURA Simulation Parameters - what should I use when?

AURA is a highly sophisticated room-acoustic module. It has been integrated into EASE, based on the CAESAR software from Aachen University. It can be considered as consisting of two different engines. One method is utilized for highly accurate auralisations at selected receiver positions, it is called AURA Response. The other one is less precise but much faster and therefore allows for the calculation at many points, that means AURA Mapping.

Can you give a brief overview of what EASE is and what it can do for me?

EASE is a software that allows the creation of a 3D acoustic model of a room and a sound system within a room.

First the geometric data for the room is entered, then data for the acoustic absorption of the materials that are on the walls and other surfaces. From this, reverberation times and other acoustic parameters can be computed, and the model can be used to test various modifications that might be made to the acoustics.

Has EASE been verified or certified and does AFMG implement quality assurance programs for software development?

AFMG develops software on the current state-of-the-art level.

EASE’s algorithms have repeatedly been tested to perform as intended. Sufficient proof has been published in renowned magazines and textbooks. For example, the latest paper addressing speech intelligibility can be found here: http://www.aes.org/e-lib/browse.cfm?elib=16985
