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."

yawningyellowyak writes "Technology Review has an interesting article on directed sound. Ultrasonic 'sound' is sent out from a 'speaker' and the distortion encountered on hitting the air produces hearable sound, but only in certain spots. You could be standing right next to someone and they would hear nothing.
One step closer to the cone of silence!"

Not to start a slashwar, but our government has redefined many standard terms in the past 8 years, so a weapon may be classified as anything more destructive than the Death Star. Everything else is called "French Toast" and is clearly non-threatening in the greater scheme of things.

That's not to say it can't be used for legitimate purposes; there are just many people who just don't trust China. Honestly, there are a lot of countries who might not be trusted with such equipment. The US is not necessarily excluded from that list, but it's mostly determined by whether you approve or disapprove of the policies of the people behind the trigger.

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.
Re:Mixed feelings on this (Score:5, Insightful)
The reason I bring this up is that lack of protest is not necessarily a sign of contentment with government. And without access to specific kinds of foreign media, there is no way for the Chinese public to become aware that government is, in fact, a mutable thing.
IOW, most Chinese are content with their government because they know nothing different or because they have been indoctrinated with propaganda about their government. By the way, this applies to a lot of people all over the world, including Americans [1].
And here come the kneejerk flamebait mods. Sorry if I've offended some of the super-patriots haunting the halls of Slashdot, but we are all products of what is around us -- and being taught from age 5 that your country is the best is hard to overcome.

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.
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?

Because it's cheaper to buy an existing product than to reinvent the wheel.
Obviously. However, as I said, there appears to be a time factor here that isn't being publicly stated. I'm sure the Chinese government could easily produce their very own "sound weapon" if they so desired.
Later they may decide to reverse-engineer,
Later? Ha! I'm sure they're ordering enough to deploy and RE.
I would be absolutely shocked if the PRC doesn't already have existing teams whose sole function is to RE stuff.
but even then it's cheaper to buy the blueprints.

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.

One of these and 2 or 3 people can effectively fight a crowd of thousands. In fact there is no reason for any government NOT to use these to quell their population and keep them goose stepping in line... except for morals.
Furthermore, if a group or government is willing to use a cheap bullet in a situation they would be highly unlikely to purchase, train crews, and deploy these expensive non-lethal weapons.
While these weapons definitely have their uses, they can also easily be abused. Perhaps even more easily than lethal weapons, since there is supposedly no lasting damage done. (Unlike rubber or plastic bullets which cause moderate too severe damage, can be deadly and are inaccurate.) I expect China to get a lot of use out of their purchase from now on.
And on a final note, a lot of these weapons CAN be adjust to cause permanent damage. A lot of the R&D for these weapons was to design a targeting system to keep them from doing that. Change some settings and depending on the weapon large portions of a targeted crowd may never hear again or may never see again.

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.

160 dB CANNOT kill. It can rupture your eardrums, but not kill. See, sound is measured in dB SPL - deciBels of Sound Pressure Level. The reference is 0 dB = 20 uPa (micropascals) of pressure.
Do some math, and you'll find out that 194 dB SPL is one atmosphere of pressure. Meaning that 160 dB SPL is about 1/1000th of an atmosphere. You experience more pressure by swimming 0.5 meters under the surface of the water.
160 dB CANNOT kill. Pressures - sounds - of 194 dB cannot kill (that's the pressure level of the NASA sonic test weapons). That's 10 meters under water, one extra atmosphere, and harmlessly encountered on a daily basis by millions of divers.
And for the record, yes I am an acoustician, and yes I have worked on sonic weapons.
