Projecting Sound 'Inside Your Head'
Gregus writes "Projecting 'hypersonic sound' has appeared here before, but NY Times Magazine (FRRYYY) has an in-depth article with its lauded inventor and its applications. John Anderton, you could use a Guinness right now." Plus this story includes screwing with Mall Walkers!
It's good to know that I'm not crazy and someone has been telling me to start those fires...
It seems like many people in the industry thought this guy was a crack-pot, and didn't believe some of his theories. However, he seems to have been able to prove himself and turn many skeptics into believers. This really does have some neat, and disturbing applications.
Yea, great, mucic for the voices i my head to sing along with. Quite badly I might add.
Eve Fairbanks says I drive a hybrid!LOL
With this technology, they can directly beam marketing into your head, and it's not like you can ignore it like you can print/t.v/radio ad's by switching the channels, or averting your eyes. Now they have the ability to force you to listen to it, whether you want to or not.
While research has proven that subliminal messages are, from a marketing standpoint, mostly ineffective, one has to wonder about the advertising possibilities of this type of technology.
Sure, there are the obvious "private advertising" applications mentioned in the article, but this kind of thing can be very interesting - and very frightening.
Picture - you're driving along a road during rush hour. Suddenly, your skull registers the squeal of tires and a massive crash. Or, walking down a sidewalk, a quiet voice inside your head whispers that you're all going to die.
Like any new technology, this one sounds fun, but is going to require some degree of regulations and control to avoid abuse.
This has the potential to be the worst invention ever. How would you feel about being forced to listen to advertisements while riding the subway? You can't turn it off. 20 minutes of commercials, or event (shudder) popular music.
I'm sib888, and I approved this comment.
Till some artist thinks its funny and puts a recording of fingernails on a chalkboard on their CD... and projects that sound inside your head.
For those that looked at me funny while I was wearing my tin foil hats: Apolgies will be accepted in verbal and written form from 6AM to 11:30PM.
Your apologies will be accompanied the cursory "I told you so"

The Sound of Things to Come
By MARSHALL SELLA
No one ever notices what's going on at a Radio Shack. Outside a lonely branch of the electronics store, on a government-issue San Diego day in a strip mall where no one is noticing much of anything, a bluff man with thinning, ginger hair and preternaturally white teeth is standing on the pavement, slowly waving a square metal plate toward people strolling in the distance. ''Watch that lady over there,'' he says, unable to conceal his boyish pride for the gadget in his giant hand. ''This is really cool.''
Woody Norris aims the silvery plate at his quarry. A burly brunette 200 feet away stops dead in her tracks and peers around, befuddled. She has walked straight into the noise of a Brazilian rain forest -- then out again. Even in her shopping reverie, here among the haircutters and storefront tax-preparers and dubious Middle Eastern bistros, her senses inform her that she has just stepped through a discrete column of sound, a sharply demarcated beam of unexpected sound. ''Look at that,'' Norris mutters, chuckling as the lady turns around. ''She doesn't know what hit her.''
Norris is demonstrating something called HyperSonic Sound (HSS). The aluminum plate is connected to a CD player and an odd amplifier -- actually, a very odd and very new amplifier -- that directs sound much as a laser beam directs light. Over the past few years, mainly in secret, he has shown the device to more than 300 major companies, and it has slackened a lot of jaws. In December, the editors of Popular Science magazine bestowed upon HSS its grand prize for new inventions of 2002, choosing it over the ferociously hyped Segway scooter. It is no exaggeration to say that HSS represents the first revolution in acoustics since the loudspeaker was invented 78 years ago -- and perhaps only the second since pilgrims used ''whispering tubes'' to convey their dour messages.
As Norris continues to baffle shoppers by sniping at them with the noises he has on this CD (ice cubes clanking into a glass, a Handel concerto, the plash of a waterfall), some are spooked, and some are drawn in. Two teenage girls drift over from 100 feet away and ask, in bizarre Diane Arbus-type unison, ''What is that?''
Norris responds with his affable mantra -- ''In'nat cool?'' -- before going into a bit of simplified detail: how the sound waves are actually made audible not at the surface of the metal plate but at the listener's ears. He doesn't bother to torment the girls with the scientific gymnastics of how data are being converted to ultrasound then back again to human-accessible frequencies along a confined column of air. ''See, the way your brain perceives it, the sound is being created right here,'' Norris explains to the Arbus girls, lifting a palm to the side of his head. ''That's why it's so clear. Feels like it's inside your skull, doesn't it?''
In the years Norris has demonstrated HSS, he says, that's been the universal reaction: the sound is inside my head. So that's the way he has started to describe it.
Just to check the distances, I pace out a hundred yards and see if the thing is really working. (I've tried this other times -- in a posh hotel in Manhattan, in another parking lot in San Diego -- but HSS is so often suspected of being a parlor trick that it always seems to bear checking.) Norris pelts me with the Handel and, to illustrate the directionality of the beam, subtly turns the plate side to side. And the sound is inside my head, roving between my ears in accord with each of Norris's turns.
The applications of directional sound go quite a bit beyond messing with people at strip malls, important as this work may be. Norris is enthusiastic about all of the possibilities he can propose and the ones he can't. Imagine, he says, walking by a soda machine (say, one of the five million in Japan that will soon employ HSS), triggering a proximity detector, then hearing what you alone hear -- the plink of ice cubes and the invocation, ''Wouldn'
The bit about different people in the car only hearing their own music is cool. The annoying pop machines and, even worse, PRODUCE ISLES, are just awful. I mean, I can look away from an obnoxious billboard etc, but there is no way to stop this! Not even plugging your ears, since it is IN your head!
Also, using it for emergency sirens? One of the biggest problems with CURRENT emergency sirens is that it is VERY difficult for the human ear to tell which direction it is coming from, because of the specific frequencies used. If it projects the sound INTO your head, there will be no way in HELL to know where it is coming from.
Another problem with using it for sirens is that it is important to hear the siren well before the emergency vehicle reaches you. This system appears to be LOS, so how well will that work? It would only work if the ultrasonic sounds can penetrate through surrounding houses and so on, which would be FAR worse than current sirens, as the walls of your house wouldn't dampen it! And if it CAN'T penetrate through your walls, then I don't see how CARS wouldn't block it, too; It is VERY important that people inside of cars be able to hear the siren!
ASCII stupid question, get a stupid ANSI
Fry: So you're telling me they broadcast commercials into people's dreams?
Leela: Of course.
Fry: But, how is that possible?
Farnsworth: It's very simple. The ad gets into your brain just like this liquid gets into this egg. [He holds up an egg and injects it with liquid. The egg explodes.] Although in reality it's not liquid, but gamma radiation.
Fry: That's awful. It's like brainwashing.
Leela: Didn't you have ads in the 20th century?
Fry: Well sure, but not in our dreams. Only on TV and radio. And in magazines. And movies. And at ball games and on buses and milk cartons and t-shirts and written on the sky. But not in dreams. No siree!

The real winner will be the engineer that develops a practical system to counter-act such a device. A small device such as a watch that can detect the signal and then send a destructive wave to cancel the signal would be good.
I'm deaf myself, and I wonder if this thing could work a lot better than ordinary hearing aids.. would be seriously cool, and be much cheaper.
I'm too sexy for you.
We have one of their units at work, and have been using it since the fall. It really does work - you're able to point sound at someone 20 feet away, yet the person standing next to them hears nothing. Also, any sound reflecting surface (concrete walls) that the beam is aimed at effectively becomes the sound surface itself. The only downsides to the unit is that bass is nonexistent - high frequencies only. Also, volume is fairly limited, but it works well enough. I believe we paid about $800 for the device, so it's not that terribly expensive.
It's really fun to aim it out the window of our building at passing people below. (God speaking to them, etc)
