NWAA Labs goes nuclear in Stereophile
Posted by Acoustics First in Articles, Company Information, Diffusion, Mentions on July 29, 2022
Ron Sauro of NWAA Labs talks about his massive test facility, speaker measurement, sound diffusion, and more in this article in the August 2022 edition of Stereophile Magazine.
In the article, there is mention of the advances that Jim DeGrandis and Acoustics First® have made in the understanding of diffusion, the developing standards for testing in the ASTM, and their published research into modelling/simulations for refining new acoustic materials.

Introducing the Aeolian™ Diffuser
Posted by Acoustics First in Diffusion, Products on July 11, 2017
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”.
