« on: September 20, 2007, 01:46:36 PM »
Hi,

I'm looking for second hand cheap acoustic foam tiles for my home studio.

I looked on ebay and they all seem to be very expensive.
does anyone know where I could get cheap acoustic foam panels?

Ordinary mattress foam is cheap and works well, but is highly flammable, as the folks at the roadhose fire found out several years ago...

have you guys heard of this stuff?:

http://www.foambymail.com/Products.html

Concerning flammability, on the page, it says:

"ALL acoustical products (charcoal & colors) meet a Class B, California 117 flame retardant specifications. Generally, this means if you were to briefly expose our foam to a flame, the foam will self-extinguish.
(NOTE: We do not encourage anyone to try flame tests themselves. We don't want anyone getting hurt. Also, please check building codes before installing our acoustic foam, because different building codes apply to different locations."

what do you think? Is this stuff to cheap to consider? Im thinking of ordering a little bit, but Im on a tight tight budget, and dont want to sqaunder my money.

thanks,
Hank

The urethane foams are a class B, in a private home they're fine.
If I reviewed the prices correctly, these are so cheap I would be concerned with actual performance.
So really if you bought them and they didnt work out for you it would'nt be that great of a loss. Thats the risk in buying the cheap materials.

Hey Randy,
thanks for the good word. I am on the fence about the aurelex stuff sold at musicians friend, it is about 4X as expensive. However, I cant find any info as to specifications. In your opinion, is the cheap stuff in the link above just as good as the aurelex? I cant determine (without getting both in my hands) if these foams are indentical in density and quality.

Ive decided to bite the bullet and get some green glue, its going to be costly (I need about $300 worth), so that and the extra sheet rock will take care of soundproofing.

I was really wanting the foam just for deadening the room, and for sheer coolness. This is my first real music room, and I want to do it to the nines (IM thinking about lining all the corners with the bass trap foam as well. Would that be retarded?). But yeah, I was just wondering if I would be getting the same thing for a quarter of the price.

thanks for the good word!
Hank

Hank,
The green glue is a good investment, I would also suggest using 3/4" drywall with it.
Insulate the wall with cotton fiber insulation or rock wool.

As for the pyramids, you can compare the NRC rating but I'm sure they will be the same or close enough. The real question is how long will it take for them to fall apart?
Also find out the recommended adhesive for their panel.

Hey man,
thanks for all the advice. What you said about the 3/4" rock, I hadnt considered it, I had just priced the run-of-the-mill stuff. Good point (and idea), no sense in cheaping out over what would probably amount to a dollar or so a sheet. Ill definitely be doing the 3/4"

By pyramids, you meant the "foam-by-mail" pyramid shapes? What did you mean "fall apart"?  :-\

I read on their site that the pyramid stuff "costs a little extra" because they had to run it through the machine again. Im assuming the run the "wedge" stuff through, which would mean much less foam. I would expect the pyramid stuff to be far less effective (due to less foam, and twice as many points where the foam is at its thinnest). I was thinking about the wedge stuff (maybe three or four inches thick) for the ceiling.

As for getting retarded with bass traps, I was thinking about lining the perimeter of the ceiling (after doubling up on the sheetrock w/green glue), and then maybe running down the corners.

To be honest, I was intially thinking the entire room ceiling and walls would be covered in foam, but reading up on it, it sounds like thats not the best way to go (even the auralex sites say this is not appropriate, and they are selling the stuff!).

Im going to focus on getting the rooms sheetrocked up for now, and then do the ceiling in foam. Ill brainstorm the rest on the fly I guess. The room in question is only 8' by 10' (with a 2'X5' recess for the closet that Im going to bust out and turn into a desk type workstation). IM using two JBL-125s, which is a lot for such a small space. Maybe I should just foam the wall that they "fire" at.

Thanks for the advice, Randy! 3/4" it is!
Hank

Pyramids and wedges are designed this way to increase surface area and therefore absorb more sound.
you want to find the balance between hard and soft surfaces, 40% - 60% soft surface area.
The cheaper foams will decay (fall apart / turn to dust) over time, especially with sun exposure.
