The Cavity Is The Absorber.
Acoustic Physics Tuned To Geometry.

Most acoustic panels are a material problem. Ours is a geometry problem. A slotted face over an air cavity acts as a Helmholtz resonant absorber. The depth of that cavity determines which frequencies are absorbed — deeper cavity, lower bass resonance.

02 Resonant Cavity Helmholtz Simulator

Certified Octave Band Sound Absorption (ISO 354)

With JOMETRY's adjustable standoff, the same tile targets different parts of the spectrum simply by adjusting cavity depth (50–220 mm). The wall is tuned specifically to the room rather than forcing the room to accept generic foam.
