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.
 

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.

It has come to my attention that EASE 4.0 will install a spyware program called XYZ. What information are you recording on my computer and what is your intended use of it?

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.

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.
