Dodecahedron: 360° Acoustic Source for Accurate Measurements
Audio Design presents the Dodecahedron — a new measurement device designed to achieve the highest level of accuracy in acoustic testing. Built with twelve loudspeakers, it delivers fully isotropic, 100% uniform sound dispersion.
This omni‑directional source enables highly precise measurements of RT30, RT20 and RT10, and is an essential tool for detailed waterfall analysis.
The Dodecahedron features a full 360° dispersion pattern, which means that measurements taken with it are significantly more accurate compared to non‑isotropic sources such as standard loudspeakers. During our initial tests, we observed substantial differences in low‑frequency response when compared to a typical speaker box.
