Aeolian™ Diffuser

|
 
Acoustics First® Aeolian™ Diffusers use a mix of technologies to create an organic quadratic diffuser. Similar to the Art Diffuser Model D mathematically, the Aeolian™ is a bicubic interpolation of a Prime Quadratic Diffuser, bridging the mathematical with the artistic. This combination creates a smoother frequency transition, wider operating range, and more forgiving diffusion pattern. Created for use in a drop ceiling grid, or direct wall mount, the Aeolian™ can be placed where you need it to optimize your acoustic space.

Construction
The Aeolian™ uses a unique design process that incorporates "implied symmetry" to defeat lobing problems. The entire diffuser is asymmetric, including the edges. Each edge is designed to vary in height by less than the width of the flange gap, creating an "implied symmetry, without actually being symmetric. This feature eliminates all symmetry from the diffuser, complementing the undulating topology of the geometry and creating a unique aesthetic, while also enhancing the acoustic effectiveness.

Installation
Aeolian™ Diffusers may be installed into heavy-duty 15/16" face lay-in ceiling grid systems. They may be direct mounted on a wall surface as well.
