The several Corel Draw 3 .CDR drawings referenced below will NOT
display in most browsers.  The idea is that you SAVE TO YOUR LOCAL
HARD DRIVE each one, then print from a compatible graphics package.
This method gives the clearest quality prints.

** I HAVE ALSO INCLUDED .GIF DRAWINGS, HOWEVER, DUE TO THE COARSE
RESOLUTION OF MY GRAPHICS SOFTWARE, THESE MAY OR MAY NOT PRINT
TO MEET YOUR NEEDS.

An office services shop should be able to print the .CDRs - BE SURE
THEY SELECT "FIT TO PAGE".  Most recent full featured graphics
packages can read and print a Corel Draw 3 (VECTOR) drawing.

The entire set of .CDR files will fit on one EMPTY 1.44 MB floppy
diskette.  Here are the clickable references, sizes, and paper
orientation.  PRINTING THIS PAGE will assist the office services
shop:

SAMPLE SILENT SOUND DEMO Q & A:

vfmdemo.htm, for a much more complete how-to-demonstrate
writeup.

I estimate it could be done for about $200 US,
though this would vary upwards if you had
to purchase a tape recorder, say, or a frequency
meter along with it.

Tape recorder, a small one, is necessary.  A
frequency meter is not, subject to conditions
below.

With the largest Radio Shack plastic project box,
it's 8" x 6" x 3".  With the 12-volt gel cell inside,
it weighs perhaps 3 lbs.

> Could you briefly describe how you demo it
> to curious onlookers?

I keep a tape recorder with sample ordinary voice
with the unit, so I can demonstrate both the 1,500
Hertz normal speech center freq.  then raise the
center frequency up until it is not audible.  At that
point, the visitor is hearing "silent sound" carrying
speech, using FM rather than nature's AM.

I also unplug the attenuator/patch cable from the
"earphone" jack on the tape recorder, which allows
the visitor to hear the ordinary voice on the tape,
which is AM (amplitude modulation).

Also at that point, the brain is using "slope tuning"
to recover the normal voice from the inaudible
signal.

I tell them this is an unclassified device which can
hypontize SILENTLY, show them the label with the U.S.
patent #5,159,703, and tell them a unit like this was
used in the 1991 Gulf War by the U.S. Army
Psychological Warfare branch to persuade, silently,
all those Iraqi troops to surrender so quickly.

That was DOCUMENTED on ITV, and you should have for
your reference (one copy, not to hand out - it's too
long) the Judy Wall article at this link:

http://www.raven1.net/silsoun2.htm

I go on to tell them that this device gets it's REAL
destructive power when connected to a voice to skull
transmitter, one of which is under construction here
in Ontario.  It can beam hypnosis silently into
someone's skull for years and they won't be aware.

** You CAN also use the Radio Shack sound level meter
to show, when the frequency setting is high, that
sound is coming out of the tweeter even though they
can't hear it.  Due to having to use the bus, I'm
restricted on how much I can carry, so I haven't used
this but once.  (Doesn't seem to be required,
actually.)

But there are a couple of important caveats if you
want to use a sound level meter:

- Radio Shack's sound level meters are 
  calibrated to match the human ear 
  response.  Since the demo unit can 
  easily tune the center frequency up
  above 20 kHz (the meter's upper limit)
  you must have a FREQUENCY COUNTER
  with you or your sound level meter
  may miss your then-ultrasound signal

- This demo unit, in order to pump out
  any kind of signal near the high end of
  human hearing (around 15 kHz) uses a
  small PIEZO tweeter, 2 inches dia.

  The readily available, simple, 
  LM386 audio amplifier chip will handle
  this frequency, but without much power
  to spare, so the actual amplitude is
  not great at 14.5 kHz, the Lowery
  patent specification.

  Therefore, especially OUTDOORS,
  a demo to use a sound level meter
  needs an ADDITIONAL STAGE of 
  amplification.  That could be added on
  to the circuit board, but room is a
  problem with the 276-158 board, or,
  an amplified speaker, like the Radio
  Shack 21-541 would be needed for a
  reliably convincing sound level meter
  demo.  (The 21-541 should also have
  it's low-frequency speaker replaced
  with a 30,000 Hz PIEZO tweeter.)

  The GOOD news is that so far,
  the sound level meter demo does NOT seem
  to be necessary, though I do have the
  equipment should that be necessary.
  The full demo would probably be used for
  a pre-arranged meeting with a group.

> Are visitors instantly convinced?

YES, as far as I can tell.

What's more, most who stop to ask questions clearly
do NOT want me to turn it on, for what they fear it
might do to them.  I think I've turned it on half a
dozen times in the last three months.
