The reflection source distance calculations are also very interesting. They would imply that the rear wall isn't a big culprit and could be ignored in my first round of treatments.
Thanks very much, your help is greatly appreciated.
Regarding where to place treatments, don't rule anything out. One approach:
- Purchase several broadband 24x48 panels that you know are effective (I use these http://www.gikacoustics.com/product/...coustic-panel/
- Using the "blocking technique" (explained in the Guide), identify the general direction of the reflection.
- Temporarily hang one of the broadband panels where you thing the reflection source might be.
- Take a fresh REW measurement and observe the effect the panel has.
- Repeat the process until you have identified the source of each of the worst reflections, and then treat those spots.
This is not a simple process. It takes time and effort, and be prepared to be frustrated. Don't ignore the ceiling as a possible reflection source, and look to furniture as a potential source as well.
And BTW, I am not a fan of foam treatments at all.
