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.

Rated 4 out of 5 by from Excellent acoustic foamThis is an excellent product, and a major upgrade from the egg crate acoustic foam sold by PE. It is very effective at absorbing sound and really cleans up the midrange. Since this model does not have a layer of vinyl, you can layer it to improve sound absorption at lower frequencies. My rule of thumb for foam thickness is 1/8th of the dimension, counting both sides. So lining the top and bottom of your enclosure gives you 2" and works for enclosures up to 16" tall. Over 16", add another inch of foam to either the top or bottom.I gave this product a 4 in features because the adhesive backing is poor, it's not strong enough to hold the foam in place and came unglued in my cabinets. Plan on using additional spray foam or double sided tape to make it really stick.

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: I like this nickname
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:
