Experiment question about sound treatment project

By the way, as far as frames go- and skill- not even necessary. Mine are nothing more than OC703 cut and wrapped in fabric. The fabric is simply wrapped around and held together on the back with pins. Same way women pinned fabric before sewing, back in the days when even women knew how to make stuff. Mine are stapled to the wall. Easy, fast, and cheap. KISS!

"To avoid the trouble of making the panels and finding out they don't help, could I simply hang pieces of the inner absorbent material to test out possible pact?"

Sounds like a good plan. I did the same thing except I didn't have any panels so I used folded beach towels to determine what was needed and then ordered the panels.

Thanks Tvad. That might be a happy middle ground.

MC -- very much in line with your thinking. Small steps, paying attention, learning, doing, making -- that adds up to genuine knowledge. I am not against the idea of eventually paying for something pre-made or even expensive. But I'd like to conclude with some justification that these things are worth it, and if I don't learn to get there (listening the whole while) I'll just be throwing money and praying for a sonic payoff.

Turnbowm -- good ideas! Why not try lots of things, all the while listening, changing, noting the difference! Thanks!
