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

Sonic Barrier 1/2" Acoustic Sound Damping Foam with PSA 18" x 24"
Sonic Barrier 1/2" Acoustic Sound Damping Foam with PSA 18" x 24" is rated 4.2917 out of 5 by 24.
Rated 5 out of 5 by from Perfect!I used 1/2" Sonic Barrier to line the inside of my Fender Rumble 75 1x12 combo. It was pretty easy to cut and install. The results were exactly what I wanted. It really tightened up the bottom end and added focus to the low mids. The entire midrange exhibited a more solid punch. I am very pleased with the results.

Rated 5 out of 5 by from Great dampening materialI bought this to replace the old dampening material in a pair of Cerwin Vega speakers I was rebuilding. I lined all the walls with it and dampens the harmonics very well. This is great dampening material for vented or ported boxes. Very easy to use and cut. As noted in another post, the glue is sticky, so make sure you get it right the first time.

Rated 5 out of 5 by from Speaker foamGood material. Easy to cut and easy to apply. The right amount of stick - can be repositioned if not completely rubbed down. One 18x24 piece will do a .5 cubic foot speaker.

Is there a rule-of-thumb for foam thickness? Next project will be 5.7 cu. ft., ported. How many sheets would be needed? Thanks.

Is it moisture or waterproof and does it handle high temperature? I need to know if it will be suitable to be used in side car doors and dash.   

Asked by: Medo
This is open cell foam so it will hold water if it gets wet. It has been tested up to 140 degrees celcius.

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 of course you will. Think of this stuff like egg crate foam. It's essentially the same stuff, but flat and dark in color. You could probably even glue it into the corners without cutting to seperate it. If this foam does not give the desired effect, you can also add poly fill, like the stuffing in a plush couch or a pillow, and that will help regulate the output with the foam. Best of luck with your project!

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
Sure, you can put it on the door, but I'm betting that you're actually getting more sound coming through ducts and the walls than the door.Unless you're very careful with how you cut it, apply it... the stuff is not particularly pretty, and I would guess that your kid will probably end up sticking stuff in it or cutting tearing bits out. I bet it will end up more of a hassle than it's worth.

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

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
i am not necessarily sure what that claim means there, but i do know that the idea of foam sound dampening is that it is used to help lower the feedback caused by the walls of the woofer box which in turn will lower the nominal impedance at different frequencies throughout the lower end. essentially, when used in a smaller enclosure, it will help lower the impedance and therefore allow the amp you are using to offer more wattage to the driver, which will make it sound like it's in a larger box. i use polyfill and/or foam liner to smooth out all the lower frequencies in any of my speaker builds that have a woofer 4'' and up, in varying levels. i personally think it makes everything sound better and less "boxed" or "boxy" and more natural all while making the response curve more linear. if you plan on using a woofer or subwoofer in a wooden or mdf box, this will prove nothing short of essential. also, if the box is sealed, you may want to use silicon caulk on the inside of the box after gluing and nailing the box together to make sure there are no air-seal leaks. this will also help to lineate everything. hope what i have offered has helped you understand better the usefulness of foam dampening. good luck on your build from one SoCal resident to another.
