Mr. Robbins shames me again...I shudda googled it!

However, as N4ZR points out, of the first 6 references,
three are acoustical, one of them in water and two in air.
Two are on-chip noise dealing with detection of digital
edges.  I couldn't open the 6th link.

The on-chip stuff is pretty much conducted noise present in
the logic lines of the chip itself.  Nothing seems 
to relate  to EMC, and radiated fields.  Additionally,
the power line antenna environment is so complex that anything
other than empirical measurements probably won't work.  Trying
to model the radiation from such a system will turn your hair
grey.  (If the 60Hz fields don't do it first)

If someone cares to educate me on 'noise flow analysis' techniques,
I'd be happy to learn.
