Office partitions as sound panels


Any one think of using office partitions attached to walls as a sound absorption alternative?

I'm building twelve 4x8 panels using 2" rigid Johns Manville 817 panels:

Look at the table showing sound absorption coefficient at 125Hz for 1" and 2" thickness. You can see that 1" panel is useless at lower frequencies in spite of 817 material being twice dense (and 2x more expensive) than standard 814 (more common). Ideal would be the panel made of two 817s (without backing) - total 4" in thickness but unfortunately there is also WAF.

Corning also sells this stuff and is more common in some areas.
Mapman, I wonder if placing 2" panels on opposite walls works the same way as 4" panels on one wall? It should.

Kr4, I have a lot of reverberation between tall walls (cathedral ceiling). It would be ideal to space panels away from the back wall but I cannot do it being forced (by layout) to set my speakers and sofa on long walls. I can always control amount of reverberation by removing or adding panels.
