On many occasions, we get asked about common ways to treat a wall (or walls) either for broadcast, podcast, or other voice recording scenario – where they not only want to tame the reflections within the room, but also block a certain amount of sound coming into – or leaving the room.
Budget is frequently an issue, major construction is usually unwanted, but effective results are always required.
We’re going to show you how to handle a room upgrade – cut down on the sound transmission and cut the room reflections – all with the same skills required to hang high quality wall coverings! Let’s see how you can cover a wall with BlockAid® vinyl sound barrier to block unwanted sound, then go back and cover that with an absorptive layer of Sound Channels® wall covering to finish it off!
This treatment is not recommended for renters, as this is not an easy upgrade to undo. However, if you have an extra bedroom you are using as Podcast studio, this is a great way to treat it… Let’s get started!
Installing BlockAid®
 1. Measure the wall for the first panel length. Mark the panel width on the wall. |
 2. Measure and Mark the length of the wall on the BlockAid® |
 3. Use a straightedge and a razor to cut the BlockAid®. |
 4. Using a trowel, apply vinyl tread adhesive to the wall, covering the whole area where the first panel is going. (You marked the wall right?) |
 5. Hang the panel starting at the top, install a few screws to hold it in place while the adhesive sets. (You will probably need a friend to help, as BlockAid® is a pound per square foot!) |
 6. Using your hands and a putty knife, smooth out all the air bubbles from behind the BlockAid® so that you get a good bond when the adhesive cures. |
 7. Repeat the steps for the next strip. Measure, Mark, Cut, Trowl, Hang… |
 8. Make sure you line up those seams! push them right up agaist each other. Smooth out the air bubbles, cut out any outles, trim any extra… Let dry! |
Good job! Now, take a breather while that dries, and notice how much less sound is passing through the walls. This is when you will notice that the sounds are now coming from under the door, and through the leaky old window. These can be taken care of in different ways…. but the easiest way is the same way you deal with keeping the cold out! Get some weather strip, a door skirt, seal the gaps around the frame of the door, and windows, maybe go out and buy some heavy curtains for the windows… if you have some leftover BlockAid®, you can always get some Industrial Velcro and temporarily stick a piece over the window!
Installing Sound Channels®
 1. Remove the Screws from the BLockAid® – if you didn’t already… then same as BlockAid®, measure the wall, mark it, measure and cut a piece of Sound Channels® and start troweling on the Chapco! |
 2. Well, when you get tired, make your friend finish troweling out the adhesive to cover where the panel is going. (You are going to overlap the seams.) |
 3. Starting at the top, hang the Sound Channels® overlapping the seam of the BlockAid® under it. Smooth out the air bubbles with your hands. Make sure it lines up well. No screws needed! |
 4. Measure and cut the next strip, carefully following a rib in the fabric, while your friend, (who is way better at troweling than you are anyway,) preps the next section with adhesive. |
 5. Best practice is to run the fabric in the same direction every time. Not just with the ribs, but in the same direction it comes off the roll. So find the top. |
 6. After you find the top, start hanging from the top, lining up the seams and smoothing out the bubbles as you go. |
 7. Keep those seams tight as you go. Keep smoothing… almost done! |
 8. Trim up the extra and repeat as many times as needed. |
That’s it!
Don’t forget to trim around those outlets!
This treatment is a common first step in treating many professional broadcast studios – it gives you extra isolation with the barrier and takes the edge of the sound reflections. Many professional environments then go back and add some additional treatments such as bass traps, diffusers, and broadband absorber panels – especially if these studios are planning on bringing in any musical guests.
This isn’t just for home studios. It works great for kids play rooms, bedrooms, home theaters, home gyms, and any place you want to block sound and tame the sound inside the room.
Customize your space as you will, but this treatment is a consistent winner for cost and performance, and is a great way to get started without breaking the bank!
Big Room… Big Boom.

When Pippin Barnett contacted Acoustics First about an acoustical issue he was having with a new multipurpose space that was constructed for the Sabot School, he was in desperate need of a solution. This space was needed for functions, activities, art displays, music classes, plays, and more, but was almost completely unusable due to the acoustics.
The large space was well conceived; large open floor plan, hydraulic door to open the space to the courtyard, bathrooms, storage and lots of display space for the student’s artwork and creations. The building was also efficiently constructed using SIPS (Structural Insulated Panel Systems), which created a grand open space with no support pillars. 
This space was ready to be used, but there was a problem – whenever they tried using the space, you couldn’t understand what anyone was saying. To say that the acoustics were “not optimal” is like saying that the destruction of the entire universe would be “inconvenient” – an incredible understatement.
Upon arrival, we took some physical measurements of the space to calculate the surface area and volume of the room, as well as got some acoustic measurements.

Whoa… Big Boom! What you are hearing is a 3+ second RT60 time; That’s more than 3 seconds of time that the sound lingers in your space at a level audible enough to interfere with other sounds.
Which is “Inconvenient,” and “Not Optimal.”
So with some magic calculations performed by Joe Horner over at the quietest office in Acoustics First,(no really – he likes it really quiet,) a solution was developed to create a space that sounded as good as it looked.
Joe prescribed 100 2’x4′ Cloudscape ceiling baffles as well as 157 sq ft of 1″ thick Sonora Wall panels to cover the solid hydraulic door – and we listen to Joe (he’s done this a lot!)
So, a short while later, the Baffles and Panels are installed and we receive an e-mail from Pippin…
“I’d say you were right on the money!”

RT60 from 3+ seconds down to right about 1 second. I’d say that’s right on the money too, Pippin!
The Sabot School regained the use of its space and everyone lived happily ever after.
I love happy endings.
Then and now… Diffusers and Don Juan.

Four score and seven years ago (1926), movies had just begun integrating sound along with the visuals, as Warner Brothers released Don Juan – syncing a 33 1/2 rpm audio disc to the video as part of the new Vitaphone system. The era of talkies had arrived, as did a new era of fake accents.
While we still have those fake accents from the days of yore (and Johnny Depp as Don Juan), we have new technologies to bring us our entertainment – high-definition video on big screens with 10.2 digital surround sound, playing in home theaters that rival the best public theatrical venues.
While we have seen (and heard) the technological evolution of movies to what they are today, we have also seen (and heard) the evolution of acoustics – and the one area I’m going to discuss today is one of the fastest evolving acoustic disciplines – Diffusion.
Diffuser design has come far from the early days of scattering sound by changing the angle of your wall, or the shape of the room to negate, dilute, or diffuse unwanted or undesirable acoustic waves. Today, acoustic diffusers are mathematical and scientific wonders, designed to be elements that are inserted into your listening environment to create an acoustic space that is open and airy.
During this evolution of diffusion we have seen the rise of many shapes; The Pyramid, the Barrel, the Binary Arrays, Flat Panel, 1D and 2D QRDs, and more… a veritable cornucopia of geometric shapes and mathematically produced profiles, which are scientifically sound, but fundamentally, inorganic.
The notes on the instruments we play, are based on math and physics, but the music we play ebbs and flows from the pounding of drums to the smooth bass lines, from the intimate vocals to screaming, and from the heavy metal acts to classical symphonies (with or without a heavy metal act). Diffusers have followed suit, changing their shape along with the changing industry – making advances as new discoveries are made.
Diffusers have become important acoustic treatments in listening rooms, recording rooms, sound stages, and theaters – embrace the diffusers! Embrace the future Don Juan’s and their terrible accents… ok… just diffusers… fine.
DIY: Back Wall Diffuser Array/Bass Trap

Getting more out of your back wall diffuser array with a simple hanging DIY array/bass trap.
One of the big “back wall” questions people have is “If I have a large diffuser array, how can I get the bass trapping I need?” A great answer to this question is to turn the entire array into a hanging bass absorber. If you are already planning on getting diffusion for your back wall, here is a great way to use that wall space for more than just diffusion.
Stuff you need:
- 4’x 8’ sheet of 3/4” Plywood
- 32 sq/ft of 4” Cutting Wedge® Classic Foam (Or similar absorber)
- 8 x Art Diffusers® – Model C (or Model F, Quadrapyramid™, or other comparable diffuser)
- 2 x IsoHangers
- 2 x Heavy rings (Think big Curtain Rings or Hanging Wire will also work)
- 2x Closet Rod/Shelf Brackets
- 2 x 7/8” wood screws and fender washers
- Construction Adhesive (Make sure it’s safe for Foam)
Assembly instructions
- Screw the two IsoHangers to the plywood, using a fender washer on each screw. These should be about an inch in from each end -drill small pilot holes first. (These will be used to hang the panel, this side will be designated as the back from here on out.)
- Use Construction adhesive to attach the Cutting Wedge® Foam to the back of the panel in a checkerboard pattern (each panel 90° rotated from adjacent)
- Use Construction adhesive again to attach the 8 Diffusers to the front of the Plywood (Follow the installation instructions for adhesive placement)
- Attach the Rings or Wire to the free end of the IsoHangers.
What you have created is a hanging panel that will diffuse mid-high frequencies and trap the lows. The hanging mass absorbs low frequency energy by moving slightly when pushed by the energy of the Low frequency Waves. The rear facing fiberglass also absorbs low frequencies by dampening the panel, but it also absorbs any of the waves that happen to get trapped behind the panel.
Hanging the Diffuser/Trap Assembly
- Measure and attach the Closet Brackets to the Wall – Use appropriate anchors! If you have standard or double wall construction without Resilient Channels, use the studs – The IsoHangers will keep vibrations from transmitting through the wall.
- Hang the panel on the Closet Brackets using the rings/wire with the Diffusers facing you and that’s it!
This simple DIY project is provided as a way for our customers to learn better ways to use our products and get more value out of the products they buy. For those customers who are planning on purchasing diffusers to make an array, or maybe already have an array and are looking to try a new configuration – this project may be what you’re looking for.
A little History…
If you embark on this little construction project, you will be constructing studio elements that have remained basically unchanged since at least the early 1970’s. Hanging plywood wrapped in studio foam or fiberglass has been used “behind the curtains” of many of the top studios for effective bass control for over 40 years – just no one has ever seen it, as it has been hidden in walls; masked as a false wall of fabric stretched across wooden louvers!

DIY: How to quiet down that noisy equipment rack
Posted by Acoustics First in Absorption, Auditorium, Broadcast Facilities, Data Centers, DIY, Government, Home Entertainment, Home Theater, HOW TO, Media Room, Music Rehearsal Spaces, Music Tracking Room, Product Applications, Recording Facilities, Recording Studio, Sound proofing, Studio Control Room, Vocal Booth on May 2, 2013
DIY Project – Rack issues
Take a few seconds and DIY fix some of the common problems with using equipment racks!
Not too many people think about their equipment racks, but many of us use them. Usually it’s something like what you see to the right – the great, sturdy, utilitarian box. Unfortunately, there are a couple inherent problems with these:
- Ringing – The metal resonates causing a ringing effect – may be masked by program material.
- Reflections – many times your rack is near sound sources causing reflections off the hard surfaces.
- Noise – Fans and other devices in the rack can make noises that are disruptive to recording.
Here are a few DIY fixes for these common problems.
- Composite foam with adhesive backing is perfect for stopping the ringing of filler panels.
- FireFlex™ acoustical foam the inside of your rack to keep the noise down.
- Use some Composite Foam to line your trays, drawers and shelves to keep items from rattling around inside the case.
- Cover your rack in Sound Channels® fabric to keep the case from causing harsh reflections.
- Make a temporary cover for the front and back with BlockAid® sound barrier with minimal ventilation cut-outs to use during takes if rack-borne noise is problematic.
