Chicago Police to Use LRAD Sound Cannons at NATO Protests

occupyallstreets:

Police in Chicago are preparing to deploy controversial sound cannons against protesters at the G8/NATOSummit next month. The so-called Long Range Acoustic Devices, or LRADs, emit painful and potentially harmful tones over long distances.

The device was created for military use, but it was deployed against protesters for the first time at the 2009 G-20 Summit in Pittsburgh. The American Civil Liberties Union later filed a lawsuit on behalf of a bystander, Karen Piper, who said she suffered permanent hearing loss, while the American Tinnitus Association said Pittsburgh protesters had been “acoustically assaulted.

They compared the sound pressure to what armed forces might face from an improvised explosive device. Massive numbers of protesters are expected in Chicago when the summit begins next month.

Notes Anonymiss Express:

Meanwhile, outside protesters will gather: engaged citizens who are concerned about a variety of issues including poverty, labour laws, climate change, war imposed on Syria and/or Iran, apartheid in Gaza, HAARP and weather wars, first nations land and water grabs, pollution and radiation, clean water and the effects of fracking, immigration law and a commercialised prison system, (dis)ability rights, energy consumption, legalisation of cannabis, gender equity, to name but a few of the items.

They will have informed themselves about sound levels and LRAD (it will not be the first time LRAD is used) and because they know the difference between two frequencies is used to get an outcome of probably something around 2.5 kHz plus the sum of the frequencies, they will have figured out several defense tactics.

LRAD

Any protection would serve to prevent the combination of the two in bodies. Foam might appear on the scene? I’m thinking maybe diver and surf suits? Diver suits also protect a major part of the head. No doubt someone will experiment with that.

If not protected, I expect avoidance tactics to be used. The protest will likely be spread out, depending on distance from truck, as it is a focused beam.

Whatever, the protestors are likely to get creative to protect themselves from “authorities” and “protectors”. And just in case, people will have read up on other types on NLW weapons too.

    That’s a damned Sape (Sound Amplification by Parallel Emission)! It’s a sound laser. And just as dangerous as a high effect light laser. While a laser can ruin your eyes, a sape can ruin your ears. Wonder what a sape may do if put on steroids. Water on steroids can cut stone; light on steroids can cut steel; sound on steroids can… bulldoze a town into gravel?

    parabolic dishes… reflective surfaces… give ’em a taste of their own medicine

      It’s a focused beam that can be aimed from the truck. You’d have to run around with those … and rather fast too.

    I wonder if it’s possible to use active noise cancellation against it.

      You mean like high frequency noise cancellation as used in microphones? Hmmm. Thinking of a beam of HF noise now, and how to intercept …

    This is where you send all the deaf people in to kick ass.

      Nope. The two frequencies combine in a body to produce a low frequency (the difference between the two) making whole body vibrate. Hurtful and making u sick. Ye need to block one of the two frequencies, preferably both. That’s why ear muffs, not even the ones used at shooting ranges are enough protection.
