Hi Tom--
Looks great. Is that a carved wood handle or furniture recycling?

It might be confusing folks that the desired sound source you are 
isolating with the dish is pink noise. Here's a re-edit that might 
make your success easier to hear. Remember, the pink noise is the 
desired, distant subject:
http://ad2004.hku.nl/naturesound/TomR/PRHSB/Three%20Section_Frags_Hinted.mov

(1) the first few seconds is just the wider-image parallel 
boundary/barrier extension in front
(2) the middle few second is a _mix_ of the above and the below (done 
in the field)
(3) the last few seconds is just the dish

If you can use a distant, natural sound source sitting in the same 
spot for the test, I think people will be able to fully appreciate 
your accomplishment.

Wouldn't it be great to hear it with EM-23 capsules with 14dB(A) less 
self noise? Rob D.
