2: LRAD SAFETY FACTSHEET FOR PROTESTERS compiled by: Ron & Frosty Crunch 2020. GET OFF-AXIS FIRST. GET FAR AWAY SECOND. Folks out in the streets: this is a short guide below to staying safe from LRADs (Long Range Acoustical Device), which is a form of sonic weaponry that police have deployed in recent protests to disperse crowds. I am sharing what I know not to cause alarm, but so that people are aware of what LRADs are and can act to protect themselves, should they be deployed at any point. I am writing this as an electrical engineer working in audio and do not claim to be an expert on LRADs or sonic weaponry. This fact sheet has been cobbled together from available information online (LRAD instruction manuals, marketing datasheets, interviews, other disparate online sources) and from professional experience working in audio.

LRADs (Long Range Acoustical Device) have been deployed at actions in many major US cities. They produce high-frequency, highly directional sound to disperse crowds. Typical LRAD maximum SPLs (Sound Pressure Level) are 140dB-160dB. This is enough to burst eardrums even at a distance. The longer you are subjected to the sound, the more severe the damage to your hearing may be. Depending on proximity, permanent hearing damage is very possible.

The best safety measure is getting as off-axis and as far away as possible before it's activated. If you can't do that:

First priority is still to get as off-axis (i.e., out of its "spotlight") as you can, as far away as possible, as quickly as possible. Side-step the beam first, move away from it second. Try not to panic and abandon caution when trying to do this.

Bring earplugs, but keep in mind they alone will not be sufficient protection for prolonged periods of time. Inventor Woody Norris said in a 2008 AP interview, "What if they wear earplugs or put their fingers in their ears? The device is designed with sufficient intensity… That doesn't do a heck of a lot." Despite that, the LRAD 100x, 500x, and 1000x instruction manuals indicate that the operator (who is standing behind the beam) and people way off to the side of the beam should wear hearing protection (such as foam plugs). Having them will be better than nothing, but do not rely on them solely.

Given the high directionality of the sound, sufficiently large obstacles create effective acoustical shadows. Treat the LRAD almost like a spotlight and find large, dense cover. That said, remember that sound is a wave: it will reflect off of hard surfaces. Account for reflection when trying to take cover.

There is a video circulating suggesting signs (depending on their construction) may provide effective acoustical shielding. There are significant trade-offs and risks with this method. It should go without saying that if you block your face with a sign, you will not be able to see in front of you, leaving you vulnerable to both projectiles and to direct attacks by police. Additionally, the sign will reflect the signal, potentially at another innocent party. Bear this in mind if you are forced to use this method.

Additionally, an LRAD is not as directional as a spotlight, and depending on the model, the beam angle can be arbitrarily focused or widened. It is safest to be behind one. Since that won't be possible (that's where the police will be), getting perpendicular to the LRAD's beam (not perpendicular to the LRADS face) will also provide cover. That may also be difficult since police will likely occupy that space too. LRADs are often mounted on a pivoting stand too and can be pointed and aimed. Keep this in mind when finding cover.

LRAD Hazard Areas (from Acoustic Deterrent Systems website - a distributor of LRAD):

A diagram of the hazard areas when the LRAD is used at limited power and maximum volume. A circle around the LRAD is labeled Operator Hazard Area (Hearing protection recommended for sustained operations). A cone shoots out from the front of the LRAD in the direction of targeted subject(s), reaching 15 degrees to each side of the LRAD's aim. This cone is labeled Tone Hazard Area (Hearing damage may result in tone mode. Do not use tone if individuals are within Tone Hazard Area. Use voice mode only.). In this case, the cone shoots 10m out from the LRAD.

Another diagram illustrates the hazard areas when the LRAD is used at maximum power and maximum volume. A half-circle behind the LRAD is labeled Operator Hazard Area (Hearing protection recommended for sustained operations). A half-circle in frong of the LRAD and a beam 40 degrees to either side of the direction of targeted subject(s) reaching out ~15m is labeled Voice-Tone Hazard Area (Hearing damage may result in both tone mode and voice modes). A narrower but longer cone shoots out from the front of the LRAD in the direction of targeted subject(s), reaching 15 degrees to each side of the LRAD's aim. This cone is labeled Tone Hazard Area (Hearing damage may result in tone mode. Do not use tone if individuals are within Tone Hazard Area. Use voice mode only.). In this case, the cone shoots 75m out from the LRAD.

Tone Beam Width: 38m at range of 75m, 25m at range of 50m, 5m at range of 10m.

im especially scared about the infants and the disabled. children born in this genocide only know the constant sound of bombing. it's very terrible.

if you can, please consider donating to nour, mother of mohammed, a disabled child and mona, a little baby girl. the family needs all the support they can get to feed the children. the fundraiser is verified.

They wear suits, but they don't even know basic etiquette.

So my trainer’s bf cheated on her. She broke up with him. He’s holding her stuff hostage until she agrees to talk with him. Which she refuses.

She trains; for free mind you; three college linebackers, a college wrestler, two martial artists, a body builder, and… wait for it…. a Navy seal. We’re gonna go get her shit for her.

Arrival:

So the super friends all jumped into one of the linebacker’s explorer and headed over to dude’s house. Ok the squad: you all know me, but the other martial artist is a little wirey hapkido guy, the linebackers are all giants (an estimated combined weight of I’d say 750-800lbs), the wrestler looks like an escaped gorilla, then the navy seal looks like your average guy but something about him is unsettling. Really unsettling. Unfortunately, the body builder had to work. Anyway, we send the Hapkido guy and the wrestler to the door first and dude answers, screams at them, and then slams the door in their face. Then the giant linebackers head over and they ring the door bell again. Lo and behold, he was much more polite, but still denied access. Finally, me and the seal join the fray. I casually make my way towards the front of the group, but the seal decides to CLIMB THE BANISTER. We all just turned and started at him completely shocked when dude answers the door. He looks at this weird mismatched group of relatively threatening individuals and one guy perched on his banister like batman. He was like “FINE. Go take what you’re looking for.”

Retrieval:

So we’re all walking through the house gathering what we think are her things and putting them into two boxes. Mind you. We are completely guessing. We didn’t even tell her we were coming, therefore we had no list of items.The only one really being productive was Hapkido, who was legitimately looking for stuff. The linebackers were just randomly picking up furniture, turning it over, and putting it back down. Just showing off how strong they were. In case the numbers game wasn’t enough, I guess they were letting him know they could break him if they wanted to. The seal was just shadowing dude in his own house. Walking behind him, not saying much, just being creepy. Then there’s me. Who was causing general mischief…. He said to take what I was looking for, that’s what I was looking for. Ahaha and the wrestler made a fricken sandwich. Because “you guys look like you have it under control, and I’m a sucker for egg salad.” We were in and out in 15 minutes.

Delivery:

So the autobots rolled out and headed towards homegirl’s spot. She was conveniently outside when we rolled up. We got out and she was like, how do you all even know each other. The truth is, we don’t. She sent us all an email once and didn’t blind copy us all. She vented to all of us about dude holding onto her stuff and we started emailing and that was that. We told her that we went to see her ex. “OMG what did you say to him?” Nothing. We’re not messenger boys. We’re delivery boys. And we gave her her boxes of stuff. She went through the first box and said that was most of her stuff. Then she got to my box and asked “Wtf is all that shit.” So I explained that I took all the batteries out of his remote controls, his deodorant, the light bulb out of his master closet, every pair of dress socks that I could find, the laces out of his running shoes, and all the toilet paper in the house. The guys just looked at me and kind of nodded like they were impressed. She then unexpectedly started CRYING and thanked us. So you have this group of meat heads all standing awkwardly with this weeping trainer. It was quiet for a second when the seal was like “So…. chipoltle?” And we all got burrito bowls.

Yes, Organised Religions serve as a poison that slows down societies and halts their progress, in addition to oppressing said societies in varieties of ways.

It preys on basic human needs and fears, then twists them into new self-serving forms that only function to perpetuate the power of the religion and its leaders.

Yet, the day to day adherents are still people who are being exploited by their elites. They should not be villainised for seeking comfort in the belief system they were born in. Only the elites and their bootlickers are at fault, not the muggles.

Also, you are comparing Urban secular women with rural religious women. They are not the same.

Even a Utopia where Organised religions have no power over the masses, people would still be free to choose how to dress and what to believe in, and that would mean letting the rural women believe in what they want to believe.

Them choosing to wear abbaias should never be grounds for viewing them as less than the urban women who choose to wear dresses and suits.
