Marko Samardžić, ex Serbian athlete, who was wearing pacemaker and was severely wounded by Vučić's sound cannon, issued a statement about these new manufactured lies about students simulating an attack so that regime can be blamed. #Serbia #lrad #soundcannon nova.rs/vesti/hronik...

@adafruit There was a video that clearly demonstrated how to #resist the effects of an (admittedly, home made) #LRAD on YouTube.
The Summary is: In-canal Earplugs, Passive over-the-ear earmuffs, and a curved plexiglass shield -- and if I remember correctly, the inside of the curve facing the LRAD (the opposite orientation of a standard riot shield) was the best way to reflect and diffuse the sound, making it possible to approach within just a few feet of the unit.

I’m seeing conflicting reports of LRAD use in Minnesota (probably not by ICE/CBP despite some reports, more likely to be state police).
Most detailed report here:
https://www.cbsnews.com/minnesota/news/minnesota-state-patrol-long-range-acoustic-device/
LRADs have been used for civilian crowd dispersal in the US before and have quite a range of operating settings, from benign focused audio transmission over a distance to REALLY EFFING LOUD AND DAMAGING TONES AT 160 dB
One of the original use cases for an LRAD is actually to communicate between ships across distances prior to boarding to provide warnings (e.g., mounted to a coastguard vessel). They weren’t really designed for civil urban use (although that’s a slippery one) but have wide military applications both as communication (including psyops) and in a more weaponised form.
Sounds louder than 85 dB(A) require hearing protection at work for context).
Interestingly even the CIA back at the height of black site torture recommend that music or noise louder than 79 dB(A) shouldn’t be used in ‘interrogation’ so that gives you another interesting yardstick.
State police say above that they are using them at the benign end of the spectrum but I haven’t seen anything that confirms this.
(I spent a whole year researching sonic weaponry/use of sound in interrogation so know far too much about this stuff most of which I never used)

Of particular importance to #iceOut organizers in #Minneapolis #Minnesota and other cities under #gestapo occupation: how to protect yourself and others against an #LRAD, including how to reflect the attack towards the attackers.

TL;DW: Get a pair of noise cancelling headphones if you’re potentially having to deal with crowd control stuff like LRADs.

If you happen to shoot then whatever ear protection you currently use will work.

#LRAD is not rad, and you might like this video if you are protesting, as is your #FirstAmendment right, and someone points one at you

Great #LRAD safety info.

tldr: They will probably use it to broadcast loudly first. Find it and move out of the cone, not away from it.

@a_fine_day @LevZadov @Lazarou
Definitely looks like a LRAD.
Which brings up a question:
Are there any ear-protective devices that can at least mitigate these?
-
I believe the trick is to carry a large curved shield, with a concave surface that reflects sound and radio, and point it back at the transmitter attacking you.
I'm sure cleverer people will be able to tell you how to tune it for a particular user's threat model.

Panik, Provokation, #Schallwaffen: Was geschah bei der #Großdemo in #Belgrad?
Am Samstag hatte der mutmaßliche Einsatz einer mysteriösen Waffe eine #Massenpanik und den Abbruch einer Großdemo in Belgrad ausgelöst. Die serbische Regierung gibt mittlerweile den Besitz von #LRAD-Schallwaffen zu. Es gibt Hinweise auf einen koordinierten Angriff und ein weiteres Waffensystem. Eine Spurensuche.
