There's quite a lot of work being done on using TetraMic for Sound Intensity stuff. I first thought of using a Soundfield for this when B&K introduced their SI wand and I heard a really poor paper at IoA Windermere. Did some theoretical work on it in the mid 80's which I'm pleased to see confirmed in practice this millenium. TetraMic's superior calibration helps here. In a 'reactive' environment, you have XYZ much bigger than W ... as you'd expect. No surprises there. > The business end appears to be a metal sphere, loosely comparable to a > bathroom in size, which will soon be filled with argon.

Presumably you know that you can't breath Argon and even Argon/O2 mixtures can give strange physiological effects due to skin counter diffusion of inert gases and other stuff .. even at 1 bar. Fon's is a Scuba Instructor and can advise on the use of Scuba for the 'presenter'. please reply to rica...@justnet.com.au NOT to the yahoo address which is riddled with spam. I never look at it. _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
