acoustic foam

[bpape]

You can just cover it with cloth if you get the 6 or 8lb density but it's hard to make it look decent. A frame would make it a lot easier to deal with and be much more stable over time - not to mention looking a lot better.

You can build frames relatively inexpensively from Pine or Poplar (my preferred) available from any Home Depot back in with the Oak boards and craft wood.

Here's some good instructions for a trap. The file is too big to attach but you can click the link at the top to get the pdf. I am going to follow them for my panels when I get around to building them.

Acoustic product advice

Late to the posting but if you want REAL benifits from treating a room correctly, go to a real acoustical company, who scientificaly measures products, charts everything, and whose results are posted with the Acoustical Society. RPG Diffusor Inc. rpginc.com FYI: FOAM IS FOAM! 1" is 1", 2" is 2" and so on... The only difference is that in RPG profile which is patented, the 1" measures like a 2" piece because of the air cavity behind the curve. other than that only two other variables should go into your decision; Aestetic look, and Class A fire rating. I know RPG has a Class A rated product and Sonex used to make one. Drop in tiles, wall panels, foam, wood, Gypsum, Kydex, Fiberglass & acrylics, your call... search RPG website, but a word of caution; You will spend a LOT of time reading about projects, then products, then test results.... Good luck As an audio consultant and an A/V consultant, I have heard good studios, bad studios, and great rooms.
have been in rooms with $1,000,000 worth of gear, and without a properly designed room treatment, no amount of gear with help your soundstage!

There are various companies, other than RPG, that provide independent test reports for their products.

All foams are not the same when it comes to absorption. Similar designs and patterns can provide similar results, but there are differences...besides the patented RPG design that incorporates and air space. (Which other companies have done as well, btw. Not to mention the fact that the user can easily incorporate air gaps behind flat foam panels as needed for an application.)

As for Class A rated foam, there are few choices. Melamine is the most popular - possibly the only - Class A rated foam material being used in the acoustics biz. RPG and Pinta (formerly illbruck-Sonex) are two of several companies with Melamine offerings.

That aside, many companies offer Class B rated foam, which is acceptable for many uses. The important thing is that the foam is rated, period. A foam that has no fire rating is a foam to avoid for acoustical uses.

I agree. I was also an A/V design engineer for a number of years, in addition to working on the road and in studios. Having posted data to verify that a product does what it says it does is important.

ok, this rockwool stuff. is that a brand name ? what about mineral wool ? same thing ?

 

[Savant]

Mineral wool is the generic term. Rockwool is a name brand. Mineral fiber is also the same thing.

 

[just-some-guy]

HOT DAMN. menards has the stuff. $30 for 4 2'x4'x4" pieces. the stuff does look like it will work very well.

and i found some very economical stuff to hang from the ceiling.

 

[just-some-guy]

this mineral wool. is it like fiberglass, in that, it iritates after touching it ?

 

[Weasel9992]

this mineral wool. is it like fiberglass, in that, it iritates after touching it ?

Yes. It's harmlessly excreted by the body over the long term, so it's completely safe, but it's definitely irritating over the short term. Wear gloves and a mask when you're cutting/shaping it.

It's worse than fiberglass, and don't forget to wear a mask.

Because there were so many types of mineral wool or rotten cotton on job sites, OSHA always made a big deal about it, when they visited a jobsite.
My nose would run like crazy and I'd get a bad cough.

If sufficient amounts of rock and slag wool are released into the air during manufacture and handling, some workers may experience temporary upper respiratory irritation. Like skin irritation, upper respiratory irritation is a "mechanical" irritation to the fibers. The irritation will subside once the exposure is discontinued. Some people are more sensitive, some less, some not at all.

Better safe...

I bet you could find all kinds of tips on line for dealing with this stuff but I'll give you a couple. Wear long sleeves and if you douse yourself with baby powder the fibers will be less likely to get into your pours. Mineral wool is nastier than rigid fiber glass because it's less stable and the glass flies more readily. A cold shower is your friend when you're done.

You know you got it good when you can feel it crunch in between your teeth.

Yes sir. Rockwool inside the mouth is something that has to be *experienced*.

thanx guys. i would be working with it outside. what is it made of, anyway ? (and don't say minerals )

now, down to building. that link has dead pics. so i will search for a good link.

placements. i remember what was said earlier. but lets be more specific. i want to focus on the areas of the room in the pic. and remember, the size has to be compatible with the size of fabric i can place over them. oh, i am working on a DIY dual sub solution, they will be placed in the corner there abouts, on each side.

Dig my MAXEL dude

ok, well, anyway. made/hung a panel today.

the room looks narrower than it is. its a digital pic thing .
