Deep Diffusorbers: Real World Application & Scalability of Amplitude Grating Diffusers Covering Ultra-Wideband Absorbers in Small to Medium Sized Venues

Modern sound systems are capable of reproducing audio at substantial levels down to 20Hz. It is therefore of major interest to control room decay rates down to the lowest octaves even in the most demanding situations. To overcome space requirements and performance limitations of velocity-based absorbers below 80Hz and at the same time provide sufficient diffusion and tailor-made absorption characteristics at mid and high frequencies ultra-wideband diffusorbers have been emerged. Real world application together with before-after measurements of such devices individually constructed of layered amplitude grating diffuser panels, porous absorber elements, and metallic rectangular Kirchhoff plates with free boundaries on resilient sheet show their performance and scalability in a variety of rooms ranging from 900 to 280,000 cubic feet volume.
