I have uploaded renderings of MLS and Quadratic Residue diffusors, if anyone can provide a link etc giving a way to calculate the geometry of a primative root diffusor, or any other types, let me know. Noodle snacks 03:26, 11 June 2007 (UTC) reply

Here's a link to a Primitive Root Diffusor calcuator: http://www.oliverprime.com/prd/ Do you have a source for the absorption notch effect? Solarbird ( talk) 18:00, 25 September 2012 (UTC) reply

Thanks, I don't have access to the software I used to make the other drawings any more though. I probably could have just calculated things by hand nowadays anyway. Unfortunately the earliest revisions of the article have been lost. I am not sure if I added that line about the absorption notch effect or not. I had a quick look through one or two acoustics texts on my shelf, but I couldn't spot that line in my cursory examination. JJ Harrison ( talk) 08:18, 28 September 2012 (UTC) reply

How woould a primary root diffuser like like? Is there animation too? Correctorgrande ( talk) 21:22, 14 July 2020 (UTC) reply
