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!
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®
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!
We are proud to announce that the Art Diffusor® Model D has been awarded the PUPN Dean’s List Gold Award for 2014!
While the Model D is one of our newest diffuser designs, it is also one of our most recognizable products and has heard the praises sung from video and audio recording and broadcast studios, editing and mastering suites, theaters and listening rooms, music rooms and practice spaces, schools and even acoustic testing labs!

Yocumtown Church of God had a bit of an issue with their multipurpose room – They couldn’t understand anything anyone was saying.
While the space was designed well with a full court, dampers on the HVAC, a stage, movie screen and a good speaker system – they couldn’t overcome the poor acoustics of the space. A great deal of work had gone into the design and they wanted an unobtrusive way to treat the acoustic problems… enter Acoustics First.
We started the work of gathering information about the space; dimensions, some pictures and a few balloon pops.
Here’s what we got.
Wow! This room is big, all the surfaces are parallel and hard, there’s very little to break up the sound… You can almost imagine what it sounds like.
You actually don’t need to imagine. Here’s a balloon pop. CLICK HERE!
What you’re hearing is about 3.5 seconds of reverberation after the balloon pop. (Not good.)
So, whatever shall we do? How will we tame this space?!?!?! Will they ever be able to have movies for youth groups!?
Sure they will! We have Joe. You remember Joe from the Sabot School Big Room Big Boom Post?
Well, I would say that Joe has a 6th sense for hearing, but since that’s one of the 5 standard ones anyway, we’ll just say Joe has great ears – and they should be. Joe’s been using his ears as his primary tools for the past 40+ years; from Studio Engineer to Acoustic Engineer. His ears are tuned instruments, and we rely on his expertise with them to get the job done right – time and time again. (He also makes a mean spreadsheet.)
So after listening to the room, looking at the data, and running some numbers – Joe magically answers the question of what do they need? (Ok it isn’t magic – Joe’s just really good at this… did I mention his spreadsheet skills?)
So Joe says, “You put 280 – 4’x1′ Cloudscape®baffles up on that ceiling and you’ll bring that room down from about 3.5 seconds to about 1.5 seconds.”
Not only does it look great…
… But now they say that they can watch movies and it sounds just like you’re in a movie theater.
That’s about the best compliment you can give us.
(And the best compliment I can give Joe is, his calculation for RT60 time was about 1.5 seconds. When I ran the measurement of the “treated balloon pop” – I got 1.501 seconds. This is why we have Joe – he can tell you what you will get, before you even start!)
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.

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.
