Product Details

Sonic Barrier 1/2" Acoustic Sound Damping Foam with PSA 18" x 24"
The Sonic Barrier 1/2" acoustic damping foam is a precisely engineered material that offers optimum absorption for its thickness. The material features our exclusive embossed surface finish that helps to trap acoustic energy and improve high frequency performance. This finish is applied to an acoustic-grade open-cell polyether foam, which absorbs and converts the acoustic energy into low-level heat. A very aggressive pressure sensitive adhesive provides easy and permanent installation onto any surface. The Sonic Barrier 1/2" foam is excellent for use in small loudspeaker projects, where bulky damping materials are not feasible. The foam will help absorb unwanted sound from within the cabinet without disrupting airflow between the driver and port. This can reduce unwanted sound reflections and prevent them from exiting through the cone or port. In small enclosures, the foam can add a valuable increase in apparent volume, which can help to offset the space taken up by the driver itself or the port. Sold in 18" x 24" Sheets

Rated 5 out of 5 by from Works Great.Used in some desktop full-range made from solid oak. I needed it to kind of "calm " the sound. It worked great. Order came fast and it did what I needed....5 stars.

Rated 4 out of 5 by from seems to deaden reflections inside speaker cabinet, but not cheaplyThis stuff seemed to work for me inside a speaker cabinet to absorb/deaden reflection/echo in ported designs where stuffing-type probably isn't appropriate. I won't say it's "like night and day", it's more a subtle thing. A large cabinet would take a considerable $$$ amount, so I've only used it on small ones. The adhesive backing really does stick, you'll need to get it right the first time which can be a pain but isn't directly the fault of this product. I've used this twice and would use again as needed.

Rated 4 out of 5 by from Good for vented subwoofer enclosuresOnce I found this foam it's been put in every vented box I make. I like it way better than nipple foam. The sticky back makes it easy to put in boxes. I'ts not too thick and doesn't take up too much space especially near ports. This foam is usually the most expensive part of the box, but I talk customers into using it, or I just let them hear it in a box compared to a bare box with no foam. There's a huge difference. I like it better than other foams because I'm the one installing it. The speaker cones sound deader when you tap gently on them in the boxes. This foam gives me cleaner uncolored bass with increased power handling. It absorbs noise and sucks up echoes. It's not going to stop a panel from resonating because it's really lightweight. To do that you need heavy material that lowers a materials resonant frequency.

Rated 4 out of 5 by from Good product, but a little expensiveThis is a good product to use for lining the interior walls of a subwoofer (at least that's what I used it for). The foam is pretty dense, and feels as though it's made from quality materials. As mentioned by others the adhesive is very strong, so make certain you have it properly aligned before applying any pressure.The only thing I don't like is the price; seems a bit expensive for what you get, but otherwise it's all good.

can i use this on the door to my kid's room?

he's in there bellowing at the top of his lungs (xbox live). the door is wood and I think the thin panels are transmitting a lot of noise. I was thinking of putting these in the panel insets - about .5" depth - and then maybe covering the whole door with mass-loaded vinyl. Any comments or suggestions? thanks - mom
Asked by: socalmom
Frame-and-panel doors like yours do transmit a lot of noise. This product is great but for covering a whole door might be a bit expensive for you. For your particular application, and if your budget is limited, you might want to get inexpensive soundboard a.k.a. Homasote and your local home depot or loews hardware. Have them cut the 4 x 8 panel to the exact size you need to cover the whole door with one piece; buy a couple yards of fabric that matches the decor, stretch it over the homasote and either glue it with spray-on adhesive or staple it from behind. Then mount the whole thing to the door with screws (being careful to screw into the thick parts of the frame and not the thing panels.) You can put the sonic barrier product behind it if you want a super-thick, super super-quiet door. You can also put mass loaded vinyl between the door and homosote, where it is hidden and held in place from both sides. The homosote accepts and holds thumb tacks or map pins, so you kid can put stuff up on it, and the cloth looks nice, and it resists damage.

More Use Info

What does this mean "In small enclosures, the foam can add a valuable increase in apparent volume, which can help to offset the space taken up by the driver itself or the port?
Asked by: TubeTom
It means that it slows down the sound waves in the cabinet, which in turn makes the volume of the speaker cabinet seem larger than it is for the purposes of calculating optimum enclosure sizes (physics of sound). Generally, with good stuffing/foam, you can gain around 10-20% 'apparent' volume.For example, lets say you calculated a small 6 liter box for a small driver, you build the enclosure to 6 liters and then put in the driver. The driver unit itself will cut into that 6 liters. Leaving you with let's say 5.5 liters. Assuming you line the cabinet with foam and gain around 10%, you are back up to slightly over the 6L that you calculated for.Also, it can help with standing waves. I would never build a vented cabinet without foam lining the walls.Hope that helps.

Is this flexible?

I plan to use this foam on my existing speakers. Will I be able to fold the sheet and push it through the 9" dia woofer cutout?
Asked by: hari
Yes it's flexible. The best way to describe it would be like the face foam on riding goggles. On a clean surface it sticks good. You'll rip the foam before it comes back off so be careful to place it right the first time.

Shipping to Canada and product info

HiDo you ship to Canada? I'm in Toronto, ON, postal code M6E2N4.Also..The pics of this product are confusing. A quarter (coin) is more than 1/2" in diameter yet the pic shows the 1/2" foam as being thicker than the coin.The other product pic appears to show a layered foam with several different widths involved.What I need is just "1/2" open-cell polyurethane acoustically absorbent foam" for a project I'm doing.Does this product actually fit *that* description exactly?Also, I need it without any adhesive backing.Do you sell this foam without the adhesive backing?Thanks
Asked by: joegold
This product fits your description as closely as anything we carry. It is 1/2" in thickness, open cell acoustically absorbent poly foam, but we do not carry it or anything similar without the adhesive backing. We do ship to Canada, no problem.

Technical details

Hello, do you have technical details for this product? I'm looking for the absorption coefficients by octave band for this product and can't find it.
Asked by: Dirk
In the right-hand column, under "Manuals/Resources," there is a spec sheet for this product. It's listed as an MSDS, but should more correctly be called a spec sheet. Here's a link for your convenience:http://www.parts-express.com/pedocs/more-info/sonic-barrier-msds.pdf
