I'm wondering if there is a method of comparing two broadband absorbers, for example, against one another using REW? Will the measurements actually give me relevant data?
As an example, I recently measured two broadband absorbers against each other, and took more measurements with no absorbers at all. The mic was approximately four feet from the absorber, as were the monitors (but they were far from the mic). I placed the absorber in the corner. The monitors were about four feet away from the absorber somewhat along the wall, and the mic was closer to the other perpendicular wall.
When I measured one absorber, the other absorber was out of the room. When measuring without absorbers, they were both out of the room.
The measurements I'm seeing in REW only vary about 2 dB or so along the frequency range, but they vary widely within those 2 dBs. I really can't make heads or tales out of them because one appears to do well in one area where the other appears not to do as well, and vice versa.
Do I need more absorbers to make informed measurements? Should I be placing the mic further out in the room? Also note that there really isn't a "listening position" per se. This is a tracking, mixing and monitoring room so there will be mics in various locations.
Thanks.
