Introducing the Aeolian™ Diffuser

Production Unit – Photo

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”.

3D Development Model

Simulations are compared to final test results before production. (Test result by NWAA Labs.)

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.

AuraGELL-O™ Bifractive Diffuser Technology!

AuraGELL-O™

Biosynthesized Bifractive Polyamide with Diffusive Biomass Technology

Acoustics First® is hankering to announce the first products made with our newly developed AuraGELL-O™ Compound. First realized by Peter Cooper and patented in 1845, this Biosynthesized Bifractive Polyamide has a “sweetness” when combined with our Diffusive Biomass Technology. AuraGell-O™ is a Bio-Polyamide compound which exhibits Bifractive properties, doubling the potency of the Biomass Diffuser Technology by carving the wave in two, thereby creating a phase cancelling stream which functions as a frequency tuned absorber.

The AuraGELL-O™ Infra-Red dissolves low-frequencies, while AuraGELL-O™ In-LIME absorbs the mid-band frequencies (Acoustics First® is cooking up AuraGELL-O™ Ultra-Violet for high frequencies).

Available in AuraGELL-O™ Barrel and Pyramid formats, you get the benefits of classic diffuser styling with the added bonus of the AuraGELL-O™ Biosynthesized Bifractive Polyamide with Biomass Diffuser Technology.

Installation is a piece of cake – Just nail it to the wall!

“We loved our AuraGELL-O™ Barrels so much – we went back for seconds!” – Angelo LeMonjello

Call Acoustics First® and get your AuraGELL-O™ Barrels and Pyramids today – because by tomorrow, they will all be devoured!

Update: Due to an outbreak of AuraGELL-O™ weevils, and massive consumer demand, we regret to inform you that this was an April Fool’s joke.

Bon appétit!

Comprehensive Diffuser Data Now Available!

Figure 1 – 3D Polar “Balloons” are used to display a full hemispheric acoustic level response, at specific frequencies, in front of the diffusive surface. This is how a 5000Hz signal would reflect off an Art Diffusor® Model D: If we could see acoustic energy, this is what it might look like!

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!

Barrett’s Technology Solutions has a Happy Easter

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!

Happy Easter Guys!

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.

Model D @ DesignDC & WBWV

That’s right. Acoustics First will be unfurling some of the wrapping and exposing the newest addition to the ArtDiffusor® Family of diffusers… the Model D.  Where can you see it?

DesignDC 2013 - September 25-26, 2013

DesignDC 2013

 September 25-26th, 2013
  Walter E. Washington Convention Center, Washington DC

Acoustics First will be set up in the main exhibit hall (in Booth 507), showing off the Model D, the newest release into the ArtDiffusor® family.  Come on down to see for yourself what all the noise is about – pardon the pun.

Another interesting development is the first install of Model D’s in a Broadcast studio.  In a move to “liven-up” the very “dead” studio to better accommodate the live recording of in-studio musicians, WBWV 88.7 FM in Beckley, WV pointed to the New Model D as their solution.
