Product Details

Sonic Barrier 3/4" 3-Layer Acoustic Sound Damping Material with PSA 18" x 24"
The Sonic Barrier 3/4" 3-layer composite damping material is a premium acoustic absorption and barrier material. It uses the three layers to achieve excellent reduction of sound energy from the inside of the enclosure to the cabinet walls. An exclusive embossed surface finish helps to trap the acoustic energy into a 1/2" acoustic foam where it is converted to low-level heat. A 1/4" foam layer covered with 1/2 lb. limp copolymer vinyl barrier separates the absorptive layer from the cabinet walls. A very aggressive pressure sensitive adhesive provides easy and permanent installation onto any surface. The relatively thin 3/4" overall thickness provides excellent barrier properties in a compact package. It can be used in small ported enclosures to eliminate acoustic energy, and at the same time prevent vibration from reaching the cabinet walls. It offers the best combination of damping and isolation to be found in a material of its thickness. Sold in 18" x 24" Sheets.

Sonic Barrier 3/4" 3-Layer Acoustic Sound Damping Material with PSA 18" x 24"
Sonic Barrier 3/4" 3-Layer Acoustic Sound Damping Material with PSA 18" x 24" is rated 4.32 out of 5 by 25.
Rated 5 out of 5 by from Works well, but don't expect rock hard dampeningI bought this based on Selah Audio's review. I am upgrading, or ruining (based on perspective) a pair of Focal profile speakers and noticed that the top and sides around the midrange/tweeter units were very lively to the touch. Adding this material to the top and sides has made a difference I can feel, literally. It did not kill all vibrations, but they are less "buzzy" and "tickly". Sorry I don't have an accelerometer to explain this better, but it has definitely reduced the higher frequency vibrations I could feel on the outside of the speaker. I would have tried thicker panels but am trying to avoid changing the volume verr much. For my first totally custom build I'm going with the thickest model. I also tried another brand, probably more designed for computer panels that didn't do much here. It was very thin and viscous, like tar or sand paper which I used in the other speaker. Did nothing by comparison.

Rated 5 out of 5 by from Speaker DampeningI used this to replace the original material used in my 36 year old Cerwin-Vega S1 speakers. The original material was falling apart. I cut it to size on my table saw. Very easy to work with. The speakers now have a very clean bass response. They sound great again! Very happy with the outcome.

Rated 5 out of 5 by from PraticalI have been a long time appreciator of the "Black Hole Isolation" sheets that are very thick and heavy. Sonic Barrier works nicely in smaller areas. It can be cut with scissors and has an adhesive back that make it a fast and easy job.

Rated 5 out of 5 by from Works well for us!I felt compelled to review this product based on a PE competitor saying that it was ineffective. We use it on all of our speakers and it performs to our satisfaction.

Rated 5 out of 5 by from Great panel dampeningI have used this on the inside of speaker cabinet walls, it does a great job. The more coverage, the better. Adhesive is very aggressive if it sits for a few days.

Rated 4 out of 5 by from Interesting stuffLike the other surface treatment foams from P-E, this isn't at its best in controlling reflected noise. Certainly, it does have some absorbent properties for incident sound, but that's not its forte. What it does do well is deaden noisy flat (metal or hardwood) surfaces. It is built up with multiple layers, one of which is quite dense, making the product surprisingly heavy. Its best use would be in eliminating the "ring" of any flat surface, such as body panels in a car, or the sides of a wood speaker cabinet. Applying this turns a nice clear "knock" into a "thud". My only complaint about it is the price, but it's at least partly understandable when you get a good look at the construction and feel the heft of it.The adhesive is pretty good, but you have to be conscious of the surface on which you intend to use it. Bare porous wood = not good. Clean, shiny painted metal = will stick like mad. If you want to apply it to wood, especially rougher textures like engineered products, you will either have to prep the surface first by sanding and sealing, or you'll have to use a stronger liquid adhesive, and consider adding some small screws with fender washers if the application involves a lot of shock and vibration.I wish P-E would tell us a little more about the environmental properties of this product. I'm always a little circumspect about using this kind of thing in an automotive application because of the temperature and vibration conditions. For instance, can this stand up to the underside of a hood? Can it stand up to the underside of a trunk lid of a black car in Miami? How about on the underside of a hood of a black car in Miami? You get the idea. More specs = better.Bottom line: recommended for deadening mechanical resonances of flat surfaces. Not recommended for reflective noise control applications or for environmental extremes.

Sonic Barrier 3/4" 3-Layer Acoustic Sound Damping Material with PSA 18" x 24"

How does this compare to acousta-stuf? I built a set of karma insignias (ported cabinet, 6.5" woofer, .38 cubic feet volume if memory serves) and used stuffing. I'm building a second pair and want to know which way to go. 

Asked by: Rich Z
Acousta-Stuf is generally recommended for sealed cabinets, where I recommend this for vented. I doubt you will benefit from the weighted foam if you cabinet is well braced, so you might consider the 1/2" or 1" standard single layer foam if the cabinet is vented.

How to remove it?

I used this to rebuild speakers that my Father built for our home stereo back in the late 50's. Unfortunately, I used too much by lining all the sides and now it's overdamped. I need to remove some but it's stuck VERY well to the wood. How can I remove it? Heat? Solvent?
Asked by: Pete M.
This foam isn't really designed to be removed. If you cannot pull it off, I would recommend a heat gun before you try solvents, a solvent might melt the foam itself.

How compressible is this foam? Is it high density?

I am thinking of using this foam to dampen the vibration of a whole house dehumidifier. I know this product is not designed for that but it seems like it may be a good choice for what I am trying to accomplish. I wanted to set the appliance on top of this foam but need to know if this foam is high density before I buy it. i.e. is something heavy just going to compress the foam to the point where it will no longer be serving it's purpose?Thanks for any info!
Asked by: LukeS
The foam is compressible, and yes, your appliance would likely flatten it. However, the product is not only foam, but also has an additional layer of fairly dense material which would not compress to any significant degree, and would continue to serve its purpose. For your particular application, you may be best served by a more robust product as the "base" for your appliance. Have a look in this category:

Using in boxes built into ceiling framing

I'm installing several in ceiling speakers in new work. I plan to build MDF enclosures for my speakers and line them with this material. What are the guidelines for box size and porting? These boxes will extend into unconditioned attic space and be covered with insulation. Boxes will fit between joists and attached to them. Holes for speakers will be cut in bottom, and drywall laid directly on top with matching hole cut through it.Comments?
Asked by: Stuart
Ceiling speakers are specifically designed and engineered to perform well mounted directly to the ceiling; no enclosures are required, nor would we have the specifications you'd need to calculate an enclosure size. It would be a moot point, as the ceiling speakers are designed to simply mount into the ceiling. Covering them to prevent the introduction of debris is not a problem, but you honestly needn't worry yourself with calculating an "optimum" box size, porting, damping, or anything along those lines.

Should the volume of this material be removed from the box volume?

Asked by: Geoffrey
With this type of product, it is not necessary to subtract the volume from the internal cabinet volume.
