The Voices In Your Head May Be Real
By John Gartner Wired.com 2-21-2
Researchers have developed technology that can project a beam of sound so
narrow that only one person can hear it. "Directed" audio sounds like it's
coming from right in front of you even when transmitted from a few hundred
meters away.
Inventors of the new "ventriloquist" technology say it could provide an
added dimension to entertainment. The military, however, is investigating
using it to confuse opponents or even inflict pain.
The Audio Spotlight is one of two competing audio transmission systems that
emit a one-foot square column of sound that can only be heard by people in
its direct path. Joseph Pompei, a PhD student at the MIT Media Lab, decided
to develop it while working at audio company Bose, which he joined at 16 as
its youngest-ever engineer.
Pompei, who used to play jazz trumpet in nightclubs in Chicago, became
interested in how sound systems reproduce and distribute music. He thought
it would be cool to "choreograph sound just like you would dancers on stage."
Pompei imagined that instead of loudspeakers blaring the same cacophony of
instruments to all parts of the room, it would be more interesting to
selectively spotlight the soloist to the left side of the audience, while
featuring the percussion up front, and then switching them around.
"Sound in real life is occurring all around you. Regular speakers only go
so far in reproducing an accurate environment," Pompei said.
Pompei developed the first demonstration systems of the technology for
installations at Sega's Joyopolis theme park in Tokyo and the Boston Museum
of Science, and he's planning to start selling it commercially soon. He
said museums like the system because visitors who stand in front of an
exhibit can hear the appropriate audio track without being distracted by
sound from other displays.
The Audio Spotlight transmitters range from several inches in diameter to
about 20 inches and generate a column of sound between one to three degrees
wider than the transmitter.
The technology could also be used to prevent fights over the car's radio
tuner, Pompei said. He put several Audio Spotlights in a concept truck from
Chrysler, which enabled passengers to hear their own radio stations -- the
kids in the back seat enjoyed heavy metal while the parents relaxed to
elevator music. "It could make for much happier trips," he said.
The Audio Spotlight converts ordinary audio into high-frequency ultrasonic
signals that are outside the range of normal hearing. As these sound waves
push out from the source, they interact with air pressure to create audible
sounds.
Pompei said the "non-linear" effect of air pressure modifies sound waves in
a consistent fashion. He wrote algorithms that "reverse-engineered" the
desired sound waves to determine the appropriate ultrasonic source signals.
According to University of Texas professor David Blackstock, high-frequency
signals are easier to focus, and control like a flashlight, than sounds
that are within the human range of hearing, which disperse in all
directions. Blackstock said ultrasonic signals "decay more slowly than
lower-frequency waves" so they are easier to send farther.
The Audio Spotlight emits sounds in the 60-kilohertz range, which,
according to Blackstock, is well above the 20-KHz limit of human hearing.
Blackstock said the first experiments to use ultrasonic sounds were
conducted underwater in the 1960s, and Japanese researchers made advances
in the 1980s but were unable to create a commercial application for the
technology.
Pompei said Audio Spotlights are currently being installed in Australia for
the upcoming Fringe Festival. Pompei started Holosonic Research Labs to
sell Audio Spotlights to corporations such as Kraft and Kodak, which are in
the process of integrating them into information kiosks and retail displays.
An alternative to Pompei's invention, which also may be commercially
available soon, is American Technology's Hypersonic Sound System. The HSS
system similarly converts audio into ultrasonic sound waves, and Blackstock
was impressed by a demonstration.
Blackstock said he heard a clear signal at about 100 meters, but then heard
nothing by moving two steps out of the audio's path. "It's remarkable, a
spectacular effect."
American Technology president Terry Conrad said the company is going into
its first mass production of chips that convert the audible sounds into
ultrasonic waves in February. American Technology recently signed an
agreement with the U.S. Army to develop the technology for a decidedly
non-commercial use: psychological warfare.
According to American Technology CTO Jim Croft, the technology could be
used to confuse opponents by making them think there was someone nearby.
Small transmitters could be kept out of sight, and ghost sounds could be
bounced off "rocks or any reflective surface" to fool people into believing
they were not alone.
American Technology is also working on a stronger version of the technology
called Directed Stick Radiator, Croft said. This "acoustic assault rifle"
is shaped like a gun, but instead of bullets, it dispenses high-decibel
sounds that would cause discomfort or even pain.
Croft said the company is developing prototypes of the debilitating weapon
that could be mounted on a jeep and used for crowd control. "It could be a
very effective first-level deterrent," he said.
Pompei, conversely, is happy to make music, not war, with his system. He
said U2's Bono is a fan of the Audio Spotlight and recently flew him to Los
Angeles to measure the acoustics during a Staples Center performance.
He would prefer that others adopt his invention to returning to the stage
himself. "I make a much better scientist than musician."

Hi -
I've only scanned this article once, but I know it is highly significant to
us mind control victims.
What this is saying is, here is a type of field, called a "torsion field"
in this reference, that is generated as a normal consequence of either
mechanical motion or electromagnetic fields, which UNDER SPECIFIC
CONDITIONS can have powerful effects on biological entities (us).
This statement by Mojimir:
"(the generators using geometrical shapes were described as well in the
excerpt of Gurtovoi's book I was mailing to the list few months ago)"
.and this new article translation point directly to so called
"psychotronic shapes", or, simple, inert objects of specific shapes which
were described in the book "Psychic Discoveries Behind the Iron Curtain" by
Lynn Schroeder and Sheila Ostrander.
These devices were demonstrated to the authors on their visit to the then
Soviet Union, and are the invention of Czech industrialist and inventor,
Robert Pavlita, and date from the 1930s.
In addition, these torsion fields, their effects seemingly dependent on
SHAPE, point to "pyramid power", and "sacred geometry", two concepts which
are often dismissed as nonsense.
We know that we are not likely to be able to sit down and build a
demonstrator device from this article, but it may give some clues to our
'power researchers' and that is why I'm sending it out.
MANY THANKS to Mojimir!
