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. Check your facts again. The LRAD products don't use the "hypersonic sound" technology of the first article, as I stated before. However, it's better stated in this Wikipedia article:
"Contrary to some beliefs, the device does not use ultrasound, nor is it a phased array; it uses an array of conventional acoustic tweeters, the same as those used in many professional audio applications, all driven together in parallel."
Now please, no matter how rude you think I was, admit you're wrong. Go back and print an official retraction or whatever, and set the record straight.
AND, stop publishing ill-conceived copy and paste mindless spew from other sources. Do some homework on your stories and get them right, or don't publish. If all you are capable of is repeating the factually incorrect alarmist hysterical bullshit that a gazillion other bloggers on the planet spit out every day, then just don't.
How many dB does it take for YOU people to consider something a weapon, or merely painful? None of these LRAD devices can produce over 130 dB at over 50 feet, and the LRAD 100x, the one likely being purchased by the Chinese authorities, can only produce 132 dB at 1 meter, 39 inches away, which just about any decent PA horn in a stadium can produce, or a cheap personal or car alarm horn:
From the official dB Drag 2008 rule book: http://www.termpro.com/dbdrag/rules/2008/section1.asp __________________________________________________ The contestant must be outside of the vehicle while the vehicle is being metered and all doors, windows, and other openings to the vehicle must remain closed during this time.
Exception - Competitors may remain inside of the vehicle during metering provided:
* They wear adequate hearing protection at all times. Removal of the hearing protection while inside of the vehicle will result in immediate disqualification.
* The competitor's maximum SPL never exceeds 140 dB. A measured SPL in excess of 140 dB will be recorded as 140 dB.
* The competitor must sign a dB Drag Racing entry form that includes a waiver stating that the competitor understands that "exposure to high sound pressure levels may result in temporary or permanent hearing loss". __________________________________________________
The "adequate hearing protection" includes those little orange foamies you see if people's ears on construction sites. Sticking ones index fingers in your ears is almost as effective, but obviously you can't do any work that way.
Now, go buy an SPL meter that'll register over 130, and go find the kid with the loudest car in town. Ask him to play some bass tracks at the volume he normally does, and stick the meter inside the car. It'll be WELL over 130 dB as a single 12" sub with 250 watts does that EASILY due to cabin gain: http://www.caraudiohelp.com/newsletter/cabin_gain.htm
So, in this Chinese LRAD context, if this "weapon" can be defeated by just sticking your fingers in your ears, would you consider my fist a weapon, if I planted it in your face? My fist would do a lot more damage and cause a lot more pain. And likely the pain would last far longer.;-)
Likewise, if I sold my fists to China, would I be selling them weapons?
The whole point is, as my other post said very bluntly and with the opposite of tact, you all (exception HEbGb) are mindless sheep that can be led anywhere.
Nah. Losing battle. Over 200 people ate this "story" hook line and sinker, having absolutely no idea that they've been 110% misled. And they're happy being misled. One, from what I could tell, knew a little about acoustics, but didn't attempt to debunk. The rest of you are lost.
I just finished reading the specs on the 100, 500, 1000, and extended range 1000. One would have to be inside 50 meters (~160 ft) to experience anything close to 120 dB, and you'd have to be within 50 feet to get 130 dB with the 1000 model. Thus, for these things to be considered "weapons" you'd literally have to be almost right in front of one to sustain hearing damage, and that would be highly dependent on the frequency of the tone being sent through it.
As an example, while changing your flat tire on the shoulder of an interstate, an 18 wheel tractor trailer drives past in the lane nearest you. You will be subjected to a fairly wide frequency band of noise reaching 125-130 dB. Now, would you consider that a "weapon", or "painful"?
IASCA, USAC, and dB Drag, the 3 car audio sound competition sanctioning bodies require competitor hearing protection for vehicles producing over 140 dB. If over 150 dB, you must be outside the car using a remote. Granted, the frequencies are much lower, usually between 50-80 Hz, where human hearing is less sensitive. However, even the 1-2 KHz range, hearing damage doesn't occur until 130 dB.
Any 12 inch car audio subwoofer today can produce over 130 dB with a 250 watt amplifier. Your average punk kid with boom in the trunk in 2008 is subjecting himself to over 130 dB of 30-100 Hz tones constantly, and they love it! It's not pain but enjoyment.
I hate being the one to write this, but someone has to. Megan isn't dead because of Lori Drew, or because Megan was 13 going through all that age entails. Megan is dead because she was bipolar.
Sadly, the world can be a cruel place, and bipolars have a harder time dealing with it, sometimes with consequences such as this. Some bipolars lash outwardly, others inwardly. Be glad Megan wasn't male, or this could have ended like Columbine.
The parent's want to blame someone else, and apparently so do most. In all the media stuff I've watched, the parents have avoided using the term bipolar, but used "ADD" and "depression" instead. This tells me the parents were in denial, or feel Megan's memory would have been stigmatized if they told the truth.
Drew would never have been charged if not for Megan's death. Therefore the judge will likely feel compelled to allow Megan's medical, psychiatric, history to be presented as defense evidence. I hope this happens and that Drew is found not guilty. If she is found guilty, the story dies and everyone forgets Megan. CLOSURE.
We don't need closure, we need discussion. We need Megan, and Columbine, and the Omaha mall shooting discussed daily. Why? Because of the underlying cause--psychological disorders.
We need to constantly be aware that people are among us whose minds work differently, and whose personalities are different. Not because they choose to be, but because nature/evolution/God has chosen to make them different.
Until we have a societal mindset of understanding about this, kids and adults will continue to kill others and themselves, be fired from jobs, abuse their spouses and children, get divorced, and all the other negative things that happen to bipolar people with much greater regularity that the population as a whole.
Doctors and medications are *not* a complete solution for this and/or most psychological disorders. We know less about the brain and how it works by many orders of magnitude compared to any other organ. Because of this, all psych meds are still experimental, when you get right down to it. Some work, some don't, some for a while, then they don't, etc. Lithium in its various forms is still the primary medication, and it's been around for 50 years. What does that tell you about the state of brain pharmacology?
I've not committed suicide (obviously), and I've not murdered anyone. Have I contemplated either, of course. Seriously contemplated either? Obviously not. However, I'm 37 years old, never been married, have trouble with relationships, and have lost many good jobs (and crappy ones), never getting any kind of career traction due to all the start/stops.
I've never lost a job due to performance, quite the contrary. I am excellent at what I do, sometimes too good. And it's the "too good" times that cause the pink slip. Why? Because with most employment, working relationships are more important than one's output or contribution. Bipolar folks, especially in a manic state, have tremendous work throughput and problem solving ability. This is one of the reasons I'm good at tech, beyond just being technical to begin with. However, at these times I am the least congenial, and people don't like to be around me. This creates conflict in "team" projects, especially ones that aren't team oriented, but are turned into team projects for idiotic reasons by management. You've all been in similar situations I would assume.
I'll guess I'll close this down, as it could be a book. Two final thoughts I leave you with:
1. Bipolar people can be turned on/off just like a light switch. Well, easier on than off, but it can be triggered externally. Those who figure this out (whether knowing a person is bipolar or not) often take advantage of it in the worst possible way. Just ask my mother about all the "collateral damage" around the house when I was a youngster.
2. Read up on bipolar disorder. If you know someone who is or you suspect may be, help that person mitigat
My god. Even spoon feeding you doesn't do the trick. You've missed the point entirely. Ok, lets try breast feeding. Back up 500 feet, clear your mind, and re-read this news story again, from the start. Open it in a new window or tab if that helps. You are familiar with browser windows and tabs, no?

Now, do you see two hyperlinks in that news blurb, the very one we're discussing? The first one is "directed sound weapon". Click that, and tell me where in the resulting blurb yawningyellowyak posts the word weapon. He doesn't. Now, there is a link within yawningyellowyak's news blurb. Click that. In *that* article on Technology Review, in any of the 3 pages, do you find the word weapon? NO!
What the fuck is the 3rd word in the original hyperlinked text that you clicked on that took you down this path? "WEAPON"! How the hell do you not get this?
It's the same as pulling into an Amoco station and once there the attendant says they don't sell gas in their pumps but milk, even though the sign out front clearly says "regular unleaded".
You got it yet? Knock knock? Anyone home? Beep beep! Ding Ding! Hello?
If you still don't get this, then I can only assume you're a U.S. kid, less than 30 years old, a result of a failed public school system that taught you zero critical thinking and analysis skills.
If so, you're a lamb waiting to be slaughtered, and worse, you don't even realize it and likely never will. Sad. More sheep for the slaughter.
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.
Not a single person to this point read the fucking article links. There is no sound weapon and it's not being sold to China. This "news" story is a fabri-fuk-ation.
This ATC company doesn't even have a fucking product. And when the Ph.D. behind the company does have a product, it's not going to be a weapon, but consumer gear. You people are idiots. Please do world society a favor and go kill yourselves to cleanse the gene pool. I mean it, go NOW! Quickly! Before you reproduce!
Is this kind of totally fabricated "news" the future of Slashdot? Clean some fucking house please or start losing your intelligent users and be left with only brain dead sheep like all who posted above me here. Sad...totally fucking sad...
