### Corel Draw Drawings, Silent Sound Demo Device Construction
April 3, 2001

Use CHIP SOCKETS! Old timers may tell you they are unreliable, but unless you like trying to unsolder/re-solder the 16 pins on the XR2206 chip if you need to replace it or troubleshoot, USE THE SOCKETS!

    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.

    > Are the items in question expensive? I MIGHT be
    > interested in paying for a demo unit. How large
    > and heavy is it when finished?

    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.
