Default [HELP] DIY College project

Hi All,

i've been looking around for days now and cannot seem to find the depths used by the RPG Omniffusor (the wooden one).

I'm currently working with discarded materials, trying to transform them into this specific diffuser.

Can anybody help me out with the correct depths for these units?

Thanks a lot!

much like an anechoic chamber, the depth defines the longest wavelength (lowest frequency) that the diffusor will diffuse. The cavity width/height "unit" dimension defines the highest frequency. Hence for a really broad band diffusor you need a huge number or very deep cells in your fractal/binomial pattern.

On the up side, the technology works very well.

qrdude for generating a QRD, Calculate a Two-Dimensional Primitive Root Diffuser for a PRD. QRD's are easier to build. If you have any other questions let me know.
