Hi all! As I mentioned in a recent thread, a friend gave me a pile of sound proofing foam. After comments in that thread and reading on the Auralex site and a few other places, I got busy. My results are in the pics below. A note on mounting: I found a wonderful tip about using T-pins. Sure enough Wal-Mart had these things, so I bought 4 boxes at ~$2.50 / box for 40. They worked really really well! They're about 1-3/4" long, hold the foam quite well, and seem to stay put - even on the ceiling. Notes on sound. The room is definitely quieter. And my guitar amps sound much clearer, transparent, etc. So for that benefit alone this was worth it, especially for $50. Not sure yet how much effect it's had on the room for recording though. I listened to a couple of recent mixes, they still sound ok, but playing CDs I have noticed better bass response. So I hopeful, but won't know until I try a new mix. As you peruse the photos below, I still have a couple of unanswered questions. Maybe you studio cats can help. 1. Poking around the web, it seems the LENRD bass traps I have are on the smallish side. It seems the Auralex ones are 12", while the ones I have are 6". I'm wondering how diminished their performance will be compared to the Auralex, and I'm also wondering who makes these. He bought them at GC, and it seems maybe Prosonic makes a similar model. Thoughts? 2. In the first pic, you'll see the bookshelf on the right side. Should I move it? I have read in a few places that symmetry is desired. 3. Any places I've put foam which appears unneeded? Maybe there are places I've missed, and I should relocate? In did put some aginst the wall opposite my amps (by the drumset in the last pic), and that may be why the guitars sound clearer.
