Product Details

Sonic Barrier 1" Acoustic Sound Damping Foam with PSA 18" x 24"

The Sonic Barrier 1" 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" foam is excellent for general loudspeaker cabinet use. The non-composite nature of this material means that it acts as a sound absorbent across a wide range of frequencies. For situations where the cabinet walls are already acoustically dead, composite barriers may not be necessary—in this case, the pure foam material can offer a lower-cost alternative with minimal difference in performance.

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. The foam can cause an increase in apparent volume, which can help to offset the space taken up by the driver or the port.

Rated 5 out of 5 by from Good productI bought 7 piece to cover my whole furnace room door serface to absorbing the sound, worked great that absorbing at list 50% of the sound, easy to installing and cutting, lucky I pick 1 inch thick that to absorb more sound from the furnace room, otherwise it may not work that well if I pick the 1/2 inch one.

Rated 5 out of 5 by from Bought it because it was on sale.I'm perfectly happy with the way this dampening material installed and worked. I usually buy the "egg crate" style, but this was on sale and I decided to try it. It's good stuff, but I think it works as well as the other stuff, so buy whatever is cheaper.

Rated 5 out of 5 by from Best Value in Acoustic Foam!!Spent days researching different options to quiet down the interior of my 2012 Mercedes Sprinter Cargo van. Needed something that had high absorption characteristics, easy application, high surface durability, and "car interior" aesthetics. This fit the bill all around, and I ordered 40 sheets. The installation was easy, and the results are nothing short of incredible. Before this foam, I could not drive at highway speeds and have a phone conversation. Now, it's like I'm driving a limo. It's not 100% silent, but the difference in is astounding.One note - this foam has a gray surface where the picture looks like its black. Even better for me, but keep it in mind.

Rated 5 out of 5 by from sound reductionI used this product to lower the sound levels of our Grandfather clock. The chiming was way to loud in the living room. I placed this product inside the cabinet up behind the clock mechanism and it worked just fine in lowering the sound of the chimes but didn't completely absorb all the sound.We need to hear the clock chime.Now it does it without being annoyingly loud.

Sonic Barrier 1" Acoustic Sound Damping Foam with PSA 18" x 24"

Per latest sales flyer, it states;.. Create an acoustically larger cabinet space, which allows a driver to work in a smaller cabinet. How much of this product would be needed to add 1 cubic feet to a 2 cubic foot box ? Using part# 260-525.

Asked by: Dysasterpiece
When we say acoustically larger, we mean a lower Qtc. This is not exactly the same thing as making the cabinet physically larger per se. If you wanted to provide the woofer you are using, we could tell you if a small, medium or large amount of fill or lining would be closest to the Qtc of a 3 cubic foot cabinet.

Do you have this foam in larger sizes?  I need  3feet x 2feet.

Asked by: rs45
We only offer this foam in the 18" x 24" size, although two sheets will cover a 3' x 2' area perfectly without cutting.

Purchased a pair of Advent Maestro speakers.  The front baffle was treated with a foam covering to reduce diffraction effects.  Would this material suffice to replace the original foam which was torn up on one speaker?

Asked by: JLindy27
Yes this will work fine for that application.

Would sonic barrier or acousta-stuf be better for absorbing back waves and reducing in-box reflections in a .2 cubic foot box made of 1/2'' mdf for a 4 inch midrange speaker that will be playing from 150 to 3000 Hz? what about mlv, ccf, or other things?

Asked by: TadCat
I would recommend Acousta Stuf for this application. The total amount required is up to you but it may required a fairly heavy fill.

Recomendations on using this product in car doors?

I have used this foam in different thicknesses in speaker boxes with good results. I am replacing speakers in the back door of my Jeep Grand Cherokee and the inside of the door looks like a good spot for this acoustic damping foam. Will it absorb too much water?
Asked by: Eric
Yes water absorbtion will be an issue since this is open celled foam. I cannot imagine it would last too long in an application like this so I would not recommend it.

Absorption data?

Is there any technical information available on the absorption characteristics of this material?
Asked by: metzb1
Yes, there is absorption info in this product's MSDS PDF. You can find that PDF in the right hand margin of the 1" Sonic Barrier Web page on PE's site. I linked the PDF here:
