Playing With Sounds in Your Head

 
Police and government aganecies can certainly use these types of devices to discredit activists (ie. make them believe they are schizaphrenic)psyops, or continually drive activists crazy with different mood altering sounds as described below in the article.
The device because of the mood manipulation potential can also become a behavior modification weapon

The sound of fingernails scraping a dusty chalkboard makes a listener
immediately squirm and cover her ears.

One company believes that there is real science behind such a reaction to
sounds. NeuroPop  http://www.neuropop.com/ is integrating neurosensory
algorithms into music to create a certain mood and evoke more intense
responses from listeners. The company hopes to market its compositions to
the movie industry and video game companies.

Its first CD, Overload: The Sonic Intoxicant, contains tracks ranging from
"chill out," meditative music to a piece that generates a feeling of motion
sickness in some.

"I want to do something that messes with people's heads," said Lance Massey,
a longtime composer of commercials and the creative director of NeuroPop.

"We've gone through all the data to find what kind of sounds or signal gets
a specific response, and then we can merge it back into an existing piece of
music or sound," said Seth Horowitz, chief technology officer of NeuroPop
and an assistant research professor at Stony Brook University
 http://www.sunysb.edu/ in New York.

Horowitz said that if he wants to get a certain response from a listener to
a piece of music, he looks at what part of the brain is responsible for the
desired response. Then, using his own data or other published literature, he
looks to find what kind of stimulus makes that part of the brain active.

"By analyzing the connectivity pattern of parts of the brain sensitive to
sound with other non-auditory parts of the brain -- parts of the brain
responsible for attention or fear, for example -- you can put together a
library of sounds that will evoke these specific responses," he said.

Horowitz said he hasn't published any studies related to his work yet, but
expects to do so in about a year.

In the past, the company tried to work with advertisers, but to no success.

"In hindsight, it's a shady area," Massey said. "They are already pummeling
us with manipulative messages and they really don't need much more help."

Dr. Mark Tramo, director of The Institute for Music & Brain Science
 http://adams.mgh.harvard.edu/brainmusic/tramowebsite/homepage.htm , isn't
convinced that NeuroPop's product is supported by solid science.

"As a rule of thumb, until the empirical work is done -- the unbiased,
experimental work -- anything that's sold could be snake oil," Tramo said.
"First comes the (research and development), then comes the product."

The connection between music and neuroscience is a field that is ripe for
study, Tramo said. So far, most of the evidence has been anecdotal.

"Humans, from infancy, acquire music as effortlessly as they acquire
language," he said. "By understanding how the brain processes music, we will
understand how the auditory system, how memory, how development, how
learning, how talent, how creativity, how all of this works in the brain."

Tramo's institute is gearing up to study the effects of music on anxiety and
depression in cancer patients and critically ill infants in intensive care
units. The institute plans to conduct rigorous clinical trials similar to
the types of trials done when drugs are tested for Food and Drug
Administration approval.

Despite the skepticism about the physiological effects of NeuroPop's music,
listeners like what they hear and see potential for interesting
developments.

"It's got a really beautiful unusual texture that you can hear," said Lucas
Gonze, creator of Webjay
 http://www.wired.com/news/digiwood/0,1412,62982,00.html , who has added a
clip of the piece to one of his playlists.

"I can imagine NeuroPop's algorithms making bright instruments fade into the
mix, intensifying climaxes, giving woodwinds a more cutting sound, and a lot
of other musical effects," he said.

Point-'n'-Shoot Sound Makes Waves

 http://www.wired.com/news/technology/0,1282,50483,00.html

Those voices in your head may be real.

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."

"..mood altering sounds as described below in the article...
..The device because of the mood manipulation.."

There is also no direct mention of modd altering sounds or mood manipulation in the correct article that was supposed to be diplayed "Point-n-Shoot Sound Makes Waves" by John Gartner. Another mix-up, sorry about that.

This may be factual...

'babylon' including america is a fear consciousness/reality mind virus...THIS is usually the way it works..rather than by technological means. Because christianity is a factor of screaming racist dodge occult rituals...'tripping into fear' can lead to these effects...rather than a pyscik opening into love and light telepathy...instant space time travel and so on....that should happen with a goddess revering religion...whther it be Islam or tibetan Buddism or paganism. Yes it also depends on your karma...you can liberate from karma and transend. Yes it is also possible that this isn't goanna happen on a 'world wide basis' (as quite a few 'new age prophets correctly predicxt SHOULD be happening...as the western freemason christian scapegoat abuse trip is (obviously) a doomed paradigm....because it is quite possible that the insane leadership of the christian sadist death cult wishes to (trying again and again to end this curse of endlessly repeating eternal hell that is their destiny...) and kill themselves (but failing, realising that thisthe 'afterlife'...a 'dreamspace' of sorts created by their insane dodge occult rituals of ultimate fear...and also that the senario has terminally fucked karma. Think more in personnel terms...how can I liberate and transend myself...and escape into a more auspicious reality.
