Mr. Hexslinger: Huh? "deep-coding", "FORTH implementation"?
...'Cuse my ignorance, but can you HEXPLAIN?
ALSO, another correlation of low frequencies that I forgot to add to
the list of nine.  Two summers ago, a road construction Company was
rebuilding the road in front of our place.  The employee who's job was
driving one of those ride-on Rego Vibratory Compactor Machines (machines
with a 4 foot diameter steel drum with centrifugal flying weights 
inside used to pack down road aggregates), produced frequencies listed
on a label on the machine to be (dependent on speed) in the range of 
18.33 to 25 Vibrations per second (Hertz).  This guy claimed that he 
often had to find a washroom to relieve himself (#2), because of these
LOW frequencies. Looks like these LOW freq's can cause serious bowel 
movements!
Q: Do you have low frequency capable loudspeakers, 100 watt per channel
   stereo power amplifiers, and a audio generator suitable to produce
   the same frequencies? 
This speculation could PROVE itself to you if your try it on your own!
