Adding Nouveau™ wood diffusers to a home theater is not as daunting a task as it may seem, and can be done with a little planning and a few tools. This install used an ingenious mounting method to ease the final install. Instead of mounting the z-track to the wall directly, it was mounted to sheets of plywood which were hung with Gorilla/Hercules hooks.
The first task was to pick a stain. You can use the back of a plank to get an idea of how the poplar will respond to the different options. Poplar has a very interesting and varied structure that will take stain differently than some other woods. Darker stains may be more consistent, but don’t reveal the character and variation in the wood. This install chose a Smoke Gray which grayed out soft areas and browned the harder heart wood. A semi-gloss clear coat was used to finish.
While the stain dried, the mounting plywood was cut down to hide behind the planks. Four hanging straps with eye-loops were then added to the top edge of each of the plywood sections, and spaced to avoid studs.
The Z-track that would normally be installed on the wall was installed on the opposite side of the plywood. This will make it easy to hang the Nouveaus onto the sheet after it’s on the wall.
After the Nouveau™ planks are finished with the staining, and left to cure for a few days, they are ready to have the mating Z-bars attached to the back. They are installed with the same spacing as the Z-tracks on the plywood sheets. This will make it easy to align them after the plywood is hung on the wall.
The Gorilla/Hercules Anchor hooks are rated to around 50-60 lbs each. The Nouveau™ planks are roughly 25lbs each (at 48 inches) and each section has 4 hooks supporting 4 planks plus the weight of the 3/8″ plywood. The hooks are installed so that the plywood will hang level – with the weight distributed evenly across all four hooks.
Finally, the Nouveau™ planks are installed into the Z-Tracks on the plywood, and moved into position. Because the z-bars were installed square and level, there is no shifting, and they hang true. The undersized plywood sections disappear behind the planks leaving the impression that the planks are floating slightly off the wall.
While this mounting method may not be ideal for every scenario, this was an effective way to install 8 Nouveau™ planks with only 8 small hook holes in the wall. These can now be installed in apartments or temporary environments with minimal damage to the existing walls – and once you are done, they’re easy to take down and reinstall somewhere else. You just need a level!
We recently received these wonderful installation pics from our friends at Big3 Studios in Florida. They redid the back wall in one of their control rooms using our Aeolian® Sound Diffusers. In a couple of the pics you can also see our Model C & Model F Art Diffusors® (black) in the ceiling!
Acoustics First® is pleased to announce our latest creation: The Aeolian™ Sound Diffuser. In some ways a simplified version of our popular Art Diffusor® Model D, the Aeolian™ is the latest in our line of ‘Organic Quadratics’. Part of the Aeolian’s™ unique design comes from its use of “implied symmetry”. Although the edges are all asymmetric, the height variations are just subtle enough to create an illusion of symmetry when installed in a standard 15/16” grid, or spaced appropriately on a wall. The lack of a uniform edge also has added acoustical benefits in the way of “randomness”.
The development process for the Aeolian™ was similar to that of our ‘Model D’. Various 3D models were created and refined, after which we ran acoustical simulations. Once we settled on what we considered the optimum design for what we were going for, a full scale 3D model was printed for lab testing. With the ‘real world’ test results in hand, confirming our predicted results, we set about making the final mold, and this new diffuser was born.
The Aeolian™ Diffuser is class A thermoplastic, and 4 lbs. per unit.
Nominal size is 23-3/4” x 23-3/4” with a depth of 5.1”.
Acoustics First® has long been at the forefront of many exciting developments in the world of sound diffusion. In the spring of 2015, we created a method to evaluate sound diffusers using particle computer simulations. Then we utilized 3D printing technology to streamline the development of new diffuser prototypes. Recently, we received a patent for our innovative Art Diffusor® Model D design. Now we’re excited to announce the release of a new comprehensive data booklet for our entire line of sound diffusers!
In essence, this booklet represents an entirely new way to view and compare sound diffusers. “With technological advances accelerating at a staggering rate, we believed it would be advantageous to compile all of the measurable acoustic parameters of these devices, in order to develop an operating profile for each.” Since sound absorption and sound reflection can both be measured with great accuracy, we foresee a use for this data, or similar data, in virtual acoustic room modeling, along with other useful applications.
Contact us for your own print copy of the Acoustics First Diffuser Data booklet (or click here to download the PDF). The electronic data that was used to create the polar diffusion balloons is also available per request (Data compiled for Acoustics First by NWAA Labs in Elma, WA).
Currently, we are working closely with other members of the industry in an effort to develop a universally accepted standard for testing sound diffusion. In the absence of such a standard, Acoustics First is presenting this data in good faith as we believe it represents the best of what is currently available.
We look forward to sharing more advances in the field of sound diffusion!
Sometimes at Acoustics First we get a call from someone who is so knowledgeable that we can’t help but be tickled that they called us to help them. We received one such phone call from Pete Heskin at Barrett’s Technology Solutions in Naperville, IL.
Pete and his team were putting together an acoustic treatment for a listening room at their facility and wanted the room’s acoustics to really showcase their lineup of high-end audiophile speakers. No joke here – these guys have over 50 years of experience in the audio industry – and they keep on the bleeding edge of audio and video. This treatment is serious acoustic business – and these are some of the most discriminating ears in audio.
Happy Easter guys!
In keeping with their high-standards and cutting edge approach, they were looking for an acoustic treatment that is as visually stunning as it is capable of treating a room containing some of the world’s greatest sound sources. As you can see, the results are simple and elegant.
The room contains an array of Sonora® panels, Silent Pictures® and clusters of ArtDiffusor® Model D‘s to make this space sound as good as it looks. (While all of their gear makes the gear junkies at Acoustics First drool…)
So, if you find yourself near Chicago, or on a “Wayne’s World” pilgrimage, stop into Barrett’s – and if you fancy yourself an audiophile – put your money where your ears are, and hear how discriminating ears listen to music…
… No Stairway to Heaven.
