Does anyone use this product as sound absorption panels?
It is 15" wide 38" height 3" thick.

ATS Acoustics http://www.atsacoustics.com/ uses Roxul in their acoustic panels, I actually happen to have 2 of their 24" x 48" x 2" panels on loan from a friend.

According to ATS data sheets the acoustical performance co-coefficients for the 3" Safe'n'Sound is the same as the Roxul AFB used by ATS Acoustics.

I bought some Safe and Sound, for the first time the other day from my local Home Depot. But using it for it's intended purpose, which is interior wall sound and fire proofing (non audiophile app, currently renovating a bathroom).

It's pretty nasty stuff. I was cutting it with a large kitchen knife, which worked well. But it does have some large, glass-like fibers in it, worst then OC703. Also not as rigid as the compressed fiberglass, kinda floppy.

If you are going to order from ATS, for a diy job, I suggest their 6 pack of OC703 (on Amazon). Good deal for folks who can't get it locally. I've ordered that, burlap, even acoustic foam from ATS, always have had correct orders with prompt service.

I made some bass traps out of Safe'n Sound and it worked great.  IME it was less irritating than 703, still noxious, just less so.  An electric carving knife works wonders.

I made some large soffit traps with the stuff.  Works great and is pretty cheap.

ok I'm going for it. I was given half a bale so, corner trap and a few panels.

I did the entire basement ceiling, and all interior walls when I built up that space around 2 years ago.

I found S&S way better to work with than pink insulation, for itching etc.  I did fill the entire bulkhead (main HVAC trunk) with pink, so I had the chance to work with both.

Vastly preferred the S&S.

Excellent for helping reduce sound transmission to the rest of the house.  An excellent investment in a little time and $.

I know local guys use panels made from it in studios.

I would say if you are going to use it for "super chunks" in the corners, just make sure you support it horizontally every other layer or so. I've read of folks using birdnetting or chicken wire for this.

The stuff definitely works for soundproofing. The above mentioned bathroom, backs up against the washer and dryer in a laundry room. After installing the S&S, it was nice and quiet in the bath, with everything running in the laundry.

Next question:  Do any of you put absorption panels on the ceiling?
My room has 10' ceilings and are exposed concrete (condo).
I don't hear much about that but it seems logical.

[PDR]

I do.
Along with first reflection sides, corner bass traps and another above the front wall QRD
The ceiling panel is half again as wide as the sides, and a bit longer as well.
All made from safe and sound.

Aha. So are those stretchers to support the roxul?
How did you attach to ceiling? Is it ok to have a few inches of air gap between ceil and panel?
For decor reasons I'm thinking it would be cool if they 'floated' off ceiling.

You'll get better bass absorption if the panels are off the ceiling by a few inches, but I'd think most of the benefit of ceiling panels would be 1st reflection attenuation, so it's not required.

I did run an experiment stacking bass traps on the floor to see if I could attenuate the floor/ceiling bass mode, and it didn't seem to do much.

Goggle "acoustic ceiling clouds", folks do it all the time. I have some 2' x 4' panels at the first reflect points on the ceiling. But also plan to add one more, right over my head, due to the listening chair sitting on a hard chair mat (the rest of the room's floor is rug over carpet).

If your tweeters are the same height off the floor as your ears, then the point half way between the two is the reflect spot on the ceiling. If not, a little math is involved.
