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.

Acoustics First Sound Diffusion Demonstration Video

Acoustic Diffuser DemonstrationAcoustics First has just released another in a series of videos to help explain acoustical principles using simple, easy to understand video demonstrations. This latest demonstration tackles the mystery of acoustic sound diffusion. Using an array of ping pong balls to represent sound visually, this video simply demonstrates what occurs when sound strikes the surface of an acoustic diffuser. First, you will see what happens when sound hits a flat reflective surface with no acoustical treatment. Acoustic Sound DiffuserThe balls all bounce at the same time and in the same direction. This represents what happens to the sound when it hits a flat reflective surface like a wall.  Then you see what happens when sound hits an acoustic sound diffuser. You will immediately notice the energy of the wave of balls is scattered in all different directions as well as deflected at different time intervals.  Diffusers, disperse or scatter the sound like crowd control, preserving the sound to maintain sound clarity without destructive interference.  This is the basic principle behind acoustic sound diffusion.
