China Buying US Directed Sound 'Weapon'
holy_calamity writes "The directed sound weapon made by US company ATC is being exported to the Chinese police, despite the public law banning sales of weapons to China. Turns out that such 'non-lethal' technologies are not covered by this law — an omission that may become more widely known if they are used to quell high-profile protests during the Olympics."
What a great way to oppress folks and not leave bloody bodies around for cameras!

I don't really know much about this device, but let's, for the moment, assume it can't actually hurt anyone, just make them uncomfortable / stun them. Is it really a weapon then?
I don't know if it's such a bad thing to provide China with safe crowd control devices. If China wants some form of crowd control they will use whatever they have, including deadly force (such as back in Tienanmen Square).
Giving them something safe to use is probably a good idea and could save peoples' lives.
I think the counterargument would be something to the effect that the US shouldn't help a government such as China's to maintain control over its people. It's a difficult moral dilemma to be sure. However, China is not Burma and by and large the population is content with their government.
Once they finished slaughtering the objectors it sure got quiet over there for a while, didn't it?

You're right, I wonder what became of that whole thing? I haven't seen that come up in the media lately... oh wait.

Unless the PRC plans on using this sometime in the immediate future, why wouldn't they simply develop this technology locally?
AFAIK, the principles behind the technology aren't all that complicated.

Economic relations between the US and the ChiComs are arguably more important than supporting those opposed to the Chinese government.
We don't need more adversaries than we have already, and the cultural war with Islam is a greater concern than how the Middle Kingdom deals with its subjects. We have no duty to sacrifice for others, and our own prosperity should be our first consideration. I say sell Beijing whatever it wants, and quit caring about how Asians handle internal affairs.

If it's not a weapon, so that these laws do not apply... then I want one!
But really, this Chinese thing looks like a mess waiting to happen. More reason to hate / distrust the United States government... for both Americans and Chinese.

We were working secretly for the military
Our experiment in sound was nearly ready to begin
We only know in theory what we are doing
Music made for pleasure
Music made to thrill
It was music we were making here until
But they told us all they wanted was a sound
That could kill someone
From a distance
So we go ahead
And the meters are over in the red
It's a mistake in the making
From the painful cries of mothers to the terrifying scream
We recorded it and I put it into our machine
But they told us all they wanted was a sound
That could kill someone
It could feel like falling in love
It could feel so bad
But it could feel so good
It could sing you to sleep
But that dream is your enemy
We won't be there to be blamed
We won't be there to snitch
I just pray that someone there can hit the switch
But they told us all they wanted was a sound
That could kill someone
From a distance
And we go ahead
And the meters are over in the red
It's a mistake we have made
And the public are warned to stay off
And the public are warned to stay off

The images of pretty affluent Chinese living in modern-looking cities we've come to enjoy in the Western media are not exactly indicative of what actually goes on over there. It's a big country with a billion people.
In any case, it's illegal to express negative feelings about the glorious Communist Party or its leaders, so I'm not sure who you've been talking to over there. Just about every Chinese I've ever met here in the US love their country, but they've rarely had anything but negative things to say about their government, regardless of the era they happened to leave.

likey it will be seen being used at the Olympics on free Tibet protesters.
the vast majority of Chinese are very happy with their government at the moment
On the other hand, it was recently reported that there were over 85,000 protests in China last year, some of them violent. That is a staggering number. I suspect these sound machines will see a lot of action.

Random Thoughts From A Diseased Mind (Not For Dummies)
What "makes no sense" is your post.
People protest to effect change. One way of effecting change is to draw attention to a problem.
In this case, people are protesting China's actions by protesting at the Olympics.
I'd say those protesters have pubes a' plenty... assuming you mean "guts" when you say "pubes."
wants to be the first monkey to touch the monolith
The "pain ray" the US has developed is pretty well suited for a totalitarian government as well. It leaves no marks, so you could also just round up anyone at a protest and subject them to microwave beams that activate the pain nerves in the skin just enough to be able to cause agonizing pain without leaving any marks . You have the double bonus of driving your victims insane from the pain without any ugly wounds to photograph and get people upset. However, China is not Burma and by and large the population is content with their government. China has a very effective ability to stifle dissent -- Tiananmen square is an excellent example. How are you going to know if anyone is unhappy if everyone is too scared to say anything? When you surf the internet in China they love to have little animated policemen popping up on your screen to remind you that you are being watched. People are scared enough there already of doing the wrong thing -- imagine what would happen if deaf people started showing up as not-so-subtle reminders of what happens to people who complain?
Imagine the scenario of one man in a truck with a sound weapon shutting down a whole protest without any ugly pictures to shock anyone into action, with no effective recourse by the protesters. This kind of thing is the way that your typical 'nightmare dystopian science fiction movie' would become reality. Once the people are unable to complain or protest, how nice would the government have to be?
I get it and I resemble that remark.
Just callin' it like I see it.
So, to work around it, all protesters need to have sonic-activated bleed-makers. Insert in the ear, or as a collar around the neck, tuned specifically to government frequencies. When the government uses said offensive device, the "sound proof" will be earmarked or collared around the victims/protesters/dissidents.
ANY time some damned government (regardless of the country, EVEN if it's the u.s.a) dares to make zero-evidence weapons, a defiant nullification of anonymity should be created in the event the weapon's use is domestic vs true battlefield. Damned weaponeers and deviant policy makers...

Your incredulous attitude is troubling.
The sound weapon being sold may be non-lethal, but who is to say they won't RE the device and make lethal sound weapons. Sound can kill. If you stand next to a speaker when 160db of sound comes out of it, you'll be dead. NASA uses sound to test the tiles on the shuttle, anyone caught inside that tester would be killed instantly when the sound came on.
Your vocabulary is mean and impoverished, but more than adequate to express your thoughts.

The worst part of this is, the fact that this sales was allowed to go through is troubling. There is very little difference between the military and the police these days here in the USA. In other countries it is much worse, and in China the two are usually indistinguishable.

Well, from the Tibet point of view, it certainly seems to have backfired. Everyone here knows about the issue due to the riots and the torch protest, but they are even more determined that Tibet is part of China.
All it's done is widen the divide between China and the west (mostly the US, of course). Perhaps that's the intent - or do you *really* think these protests are spontaneous and not orchestrated in some way?
A documentary was shown recently on Chinese TV, in English, outlining the history of Tibet. It was very interesting. It went right back to when Britain invaded, and included the meddling by the US to try to encourage them to become independent (presumably to try to counter "evil communism"). It also covered the atrocities perpetrated by the Tibetan leadership using their 'caste system' and used that as justification for removal of their leadership - seemed reasonable.
I wish they'd publish it more widely because I'd love to hear 'the other side', so to speak. I'd also like to see it again...

actually, the grandparent says some facts. believe or not, here is a huge and growing middle class in China, especially in large cities. In large cities like Beijing and Shanghai, the average income is about $300/month, if not higher (but with common goods much cheaper than here). And stores like starbucks is very popular there, who sells coffee at the same price as in US, if not higher. I am not saying that there is absolutely no people earn $10/month in factories, but the inflation in China and devalue of dollar here the same time, it will be very hard to find a wage at that level. China is not in Africa, after all.
I just filed a patent for "direct sound earplugs"! Should be rich by the end of the year.
So a better example would be for me to protest your daughter playing with barbies because I don't agree with what you the parent do? Drawing attention is a valuable tool, but protesting the olympics is not going to make anything better, especially when the olympics is pretty much the longest standing global gathering where representatives from around the world join IN PEACE to compete. But.. then again.. Babies will cry. Why not protest China instead? Isn't that the point? Why not protest chinese products. Anything that is a bit more 'relative' to the purpose would make more sense.

Last bit of Chinese crowd control I saw used a tank - they want to switch to non-lethal sound weapons, I think this is a good thing.
It's not like we haven't violated every other weapons treaty thrown at us, or sold terrible weapons to terrible people in the past.
I hear accelerating tiny bits of metal towards people works perfectly well for killing them, and as China has both the capability to do so and few compunctions about doing it, I don't see them making Killer Scream Mk1000s.

This is outsourcing, simply. The weapons industry need to run large scale tests, and they don't want to have too many high-profile cases too close to home. By making this kind of 'loophole' in the law they get to test their controversial weapons without too much public outcry, and if things get too noisy, the government can say "By God, you are right! Fancy how we could have overlooked that ", and of course it takes a lot of time to change a law.
It doesn't just happen to be in China. China wanted it for entirely political reasons (which is fairly common) - basically, to demonstrate that the rest of the world agrees what a wonderful and politically stable place they are now. In particular, the torch relay that people were protesting at was intended to show world unity with China and demonstrate that Tibet was still a part of China.
Also, China is apparently doing some pretty nasty things internally in order to clean up before the games...

Did you read both? And after doing so do you not realize that the author of this "news" blurb co-mingled two completely different types of technology from two different articles in an effort to portray a device with the characteristics of both? A device which doesn't exist? Yes, both pieces of tech come from the same company, ATC, but they are completely different, and have completely different applications. He crafted this shit to make it appear something exists in the real world that doesn't. When you read the article at http://www.technologyreview.com/Biztech/13597/ that is double linked through his hyperlink "directed sound weapon", did you read the word "weapon" anywhere in said article? No, you didn't, because it's not there. The ultrasound device can't reach anywhere close to the sound pressure levels of that "LRAD" device, which is nothing more than a high power high efficiency compression driver and horn. This LRAD is little different than the civil defense (tornado warning) sirens installed in cities and towns all over the US, technology that is decades old, and has never been considered a weapon. Again, this is totally fabricated, sensationalized, BULLSHIT. Plain and simple. Put your common sense cap on. Please.
This reminds me of "Project X", a fictional sound weapon in Atlas Shrugged, both in nature and in likely use.
If I'm not mistaken the tolerance decreased sharply after the event. On a more macro scale I feel more sorry about this than for the individuals who were arrested or maybe killed in the incident.
Don't quote me on this.

I would like to know what to classify you as. First, you immediately begin ranting that the article is entirely false and claim that no one has read the article. Second, you're making claims that words don't exist in an article that do actually exist. Go read the article you just linked and use your browser's search function on the word 'weapon'. I count 7 not including tags and comments. So, what are you? A shill? A troll? Angry at something? Politically motivated? I can't really understand what I'm replying to but I felt it must be done.
Why don't you go to ATC's website and check out the specs? 100+ dB @ 300 meters, which by common standards will cause lasting hearing damage after only 15 minutes. If you go to one of the reSELLers of ATC's products you'll see that there are at least 2 LRAD products that specifically list that they can be used for "behavior modification" in addition to their communications benefits. Both the 500 and the 1000 series product list a sustained power output of 146dB, which equates to hearing damage in seconds.
So I'm really not sure where the confusion about this "device" is coming about. This was designed for "behavior modification" directly. It has offensive capabilities. Its a weapon and an American company is selling it to China. How much Koolaid have you been drinking? This is a Bad Thing(tm).
"Don't feel bad for me child; I'm the monster that hides under your bed."
"...and in China the two are usually indistinguishable."
No.
I just returned from my second trip to China and it is VERY easy to tell the difference. The uniforms are completely different and different colours. Also, there are at least two different types of police forces in China, just like in the USA.
There are the "local" police who wear the blue uniforms like in the little pop-up animations that are only shown in Internet Cafes. I never saw one of those pop-ups. (I wanted to see it, actually.) I've seen local police alone or in pairs, and I've seen male and female officers.
And there is what can be considered the "People's Liberation Army Police". Their uniforms are a light green, different from both the local police and the PLA uniforms. I saw these folks, always in pairs, at various national historical sites. I always saw them in pairs, and it was funny that the two guys (I never saw a female PLA Police officer while I was there) in the pair were always nearly the exact same height. Strange.
Also, the PLA Police are easier to spot because of the bright white holster/harness thing that they wear for their sidearms. It consists of a white belt with a white strap that on a right-handed officer would go over the left shoulder down to the right side to connect to the belt and onto the bright white holster holding what appeared to be a some form of 9mm semi-auto pistol.
The real "Army" uniforms are a different color. The different branches have different color uniforms, dark blue, light blue, and a dark green (sort of like the Marines in the US wear), but none of them have the light green color of the PLA Police.

I think we're more likely to *hear* it used at the Olympics...
Things need to be put in perspective. I criticize the U.S. all the time, but I find myself defending the U.S. against foreigners when I go abroad. My brother who is a bleeding heart liberal told me the same thing happens to him.
Also, China has much to criticize, but I think this is just taking everyone's focus off the problems in the U.S. (or whatever country you are from). We aren't the great country that we are taught in school (well, I think it is a great country but we have done many terrible things that we should admit to, move on and never repeat - such as the genocide of the Native-Americans, enslavement of a race of people and then discrimination against them, assassinations and coups perpetrated against democratically elected leaders, but ones who we didn't like, all the shit going on now that Slashdot talks about with our freedoms and privacy, and the list goes on).
Anyway, criticism is important. I just don't want everyone focusing only on China, as our government also needs criticism (so it will hopefully improve).
The link to the earlier slashdot article describing directional sound via ultrasound has nothing at all to do with this (LRAD) product.
LRAD is just a big loudspeaker (actually a bunch of regular tweeters). There's nothing "directional" about it, other than that fact that *all* speakers are directional at high frequencies.
This is 100% hype nonsense. Read the wiki:
http://en.wikipedia.org/wiki/Long_range_acoustic_device
There is no "weapon" any more than any other speaker or bullhorn. Enough with the sloppy reporting, slashdot.

It's the Chinese government's own figures. They have been widely reported. Here are a couple of links and I am sure Google can provide many more. (That tresriogrande troll might want to check a few before shooting his mouth off next time.)
For instance: http://www.nytimes.com/2006/01/20/international/asia/20china.html
A paragraph from http://www.cpj.org/Briefings/2006/DA_spring_06/china/china_06.html
"Mass incidents" is the term the Chinese government uses to describe demonstrations, riots, and group petitioning. In January 2006, the Ministry of Public Security announced that there were 87,000 such incidents in 2005, a 6.6 percent increase over the previous year. Protests over corruption, taxes, and environmental degradation caused by China's breakneck economic development contributed to the rise. But some of the most highly charged disputes have occurred over government seizure of farmland for construction of the factories, power plants, shopping malls, roads, and apartment complexes that are fueling China's boom.Leave the gun, take the cannolis.
I apologize for not explicitly defining every single absolute. Obviously I, and the submitter of the article, were not perfectly clear in such statements. I will attempt to fix this issue immediately.
The article, the first link in the submission, which ultimately leads down to http://www.technologyreview.com/Biztech/13597 is a tech piece from May 2004 describing a hardware device for deploying sound along a narrow beam and being able to control and direct it. This first article describes the technology behind the device that is listed in the second link of the submission which leads to http://www.newscientist.com/blog/technology/2008/05/loudhailer-or-weapon.html, a product review as of May 2008.
Here is where the disconnection has occurred and again I apologize. Both articles are speaking of the same thing. The first article relates to the technology in a general scope that the product in the second article is based off of. While the May 2004 article doesn't explicitly discuss that the technology can be used to modify behavior, it is indeed the same technology being used for the LRAD product being sold currently.
For future correspondence, instead of using so many words for personal attacks, assumptions, and generally unintelligent conversation you should concentrate on looking at the sources displayed. I understand that today's Slashdot may be suffering from some quality control issues but that is a far cry from being able to pen every reader into the same field. I hope I've been able to clear up this inconsistency for you.
"Don't feel bad for me child; I'm the monster that hides under your bed."
The vast majority of Chinese ARE happy with their government. It is NECESSARY: China is not like Russia, they do not control the populace with a secret service and giant army, they HAVE to keep the people happy.
If you would like an example of one way they do this, check out the article on slashdot a few days ago saying 60-70% of people actually favor censorship of the internet. This is a result of a government propaganda campaign against pornography. In China there is a TV station that broadcasts nothing but patriotic songs. I thought they were horrible (the music is very bad and repetitive), but when I mentioned it to a girl there, she told me she really liked that channel. The music is motivational I guess.
The main way the government keeps their people happy is by growing the economy. It is true a lot of people in the country are still very poor, but they are still better off than 10 or 20 years ago. Think about it....throughout most of the history of China, famine has been a periodic way of life. Compare that to now, when there is not likely to be a famine within the foreseeable future. This is a good thing.
Finally, I'm not sure about the Chinese you've talked to, but in general I've found if you talk to the young ones, you will find they absolutely love their government. If you talk to the ones that were college age around the time of the Tian-An-Men square massacre, you will find they are unhappy with the government, but their unhappiness is mostly that the government is not changing fast enough, they don't want to destroy the government. Finally, if you talk to some older people, you might find that they are unhappy because they miss the times of Mao Ze Dong.
Qxe4
For all the people complaining about this, what would you rather have them use bullets instead?
How many protests were there in the US last year? Then compare population/population density.
The fact that there were over 85,000 protests shows that a LOT of people are not afraid to protest in China. They feel that it is worth it to protest their causes. If interviewed, I bet you would find that a lot of the protestors aren't all that upset with the government, just with specific policies. Protests are being used as a way to let the government know that change is requested for those policies, not necessarily as an attack on the government itself.
That said, if any of these protests involve incitement to violence or rebellion, I am sure these machines will be used. I believe that the bullhorn will still be used to combat most of them however, and it will probably be very effective.

How many protests were there in the US last year? Then compare population/population density.
The US is about 1/4th the population of China. If there were 20,000+ "mass demonstrations" last year then the main stream media is doing a much better job of suppressing the news than even I give them credit for. I suspect if it was even a tenth of that Cheney would have declared martial law a long time ago.
I am not sure why this post has generated such contention. The Chinese released the figures. The Chinese bought the sound equipment. It isn't that much of stretch to think they are going to use it when they feel they need to do so. And like so many of these technologies (e.g. taser guns), the justifications for their use tend to expand rapidly.

Wow, after your vitriol filled comment you look quite the regular ass, don't you?
There is historical proof that sound kills. During WWI there were numerous cases of persons being killed near the proximity of explosions with no external injuries (ie no shrapnel or entry exit wounds). These persons had various internal injuries, but not from being hit by anything. It was later determined that the sound of the explosions caused internal organ ruptures. I'm not sure why 160dB is considered lethal, 200 dB is generally considered enough to cause: the lungs to rupture, and/or air embolisms which causes death. So if you can survive ruptured lungs and embolisms, then no sound isn't lethal to you and congratulations on making the medical books.
.05 atm .001 atm
By the way every 10 dB = a 10 fold increase in power and intensity.
atmospheric pressure is about 101,000Pa
Let Z = sound pressure of 160 dB
160dB = 20 log (Z Pa/0.00002) = 2000 Pa ~
not
and 194dB ~ 100,237 Pa ~ 1 atm
and 220 dB ~ 19 atm
and 250 dB ~ 620 atm which is more than six times the pressure at the bottom of the Marianas Trench. So if you can survive 600 atmospheres of pressure, then no sound can't kill you and you're also not human, or any form of life that originated on this planet. And that's no BS. It's simple logarithmic math. Or maybe not so simple.
So I guess someone needs to do a little better math.
But just because the sound isn't some high number of atmospheres, it doesn't necessarily follow that it can't kill you.
There is truth that the frequency counts. But not strictly in the way that is being put forward here. It is more about whether the sound is periodic or non-periodic (the sound weapon is non-periodic, as is a bomb blast). Of course not all ears are created equal, and my statements of course oversimplified things, sound is a complex topic. But all the medical and scientific experts agree that sound of sufficient power will kill you. Because it is already known to have killed in the past.So unless you can explain away the historical evidence then there really is no argument. I have no doubt these weapons could be modified to kill.
