Thanks for the URL. I wonder how accurate their
calculated surface acoustical image is to the real
world? There was a book published in the 1960s' that
had lots of interesting photos of sound that were
taken with a moving arm that had a microphone attached
to the end.
The arm swept up and down to capture the Y axis and
the platform moved backward in steps to record the X
axis.
The idea being that the arm would start close to the
speaker which was emanating a fixed signal or signals,
as the microphone moved up and down it took point
source readings that created a 2 dimensional pattern
sideways to the emanation of the sound matrix of the
acoustic wavefronts.
I think I made photocopies of that book when I
borrowed it from the library years ago because the
photos were so intriguing and done in real time, if I
ever find it again, it might make a neat page. The
experiment isn't that complex to duplicate.
But it led to the realization of scanning a 2D matrix
as opposed to the more complex 3D matrix and what it
would entail.
Chuck Shramek was originally using an orgonoscope to
detect point source variations, then figured out that
a CCD could be used to generate 2D images by scanning
on the X,Y matrix which resulted in the pictures at;

There was a company many years back who were selling
rare earth piezos that were about 5" across, 2" thick,
in a plastic donut type housing that focused on a
small cylinder shape that was threaded for a 10/32"
screw thread. You could attach this piezo to a wall
or any of semi-flexible medium, then inject audio into
it to make the entire surface vibrate.
At the time I was going to tech school and shared a 3
bedroom apartment with 2 other schoolmates...our
downstairs neighbors had a penchant for cranking up
their music although we asked them to keep it down.
So we pressed two of these transducers against the
floor of their bedroom one morning about 1AM and
turned on some music with the bass cranked up....the
whole floor started vibrating...we left it about 15
minutes and they never turned theirs up after that.
In experiments with those transducers the sound wasn't
very good though with an equalizer you could
definitely improve it. The nature of the vibrating
medium made all the difference, with the greater
flexibility bringing out the higher frequencies and
the less flexible having a lot of lower frequencies.
Ron Barker used to work as night security manager at a
local hotel. He said one group rented one of their
conference rooms and were using software called
Turtlebeach to send various acoustic signatures down a
network transmission line, then comparing what was
sent with what was received. They could then adjust
the components of the signature to compensate for
nodal type interferences inherent in the wire.
Kind of neat that the wire was 'tuned' to the load,
much like Avramenko's claim of the single wire power
transmission using his 'Avramenko plug' as at;

Being able to make an entire body vibrate in a
controlled fashion is one step closer to a crude
approximation of a bose einstein condensate, similar
to Keelys idea of 'graduation'.
