ICE is now using LRAD to disperse crowds. How to defend against it.

8. Short transcript

yeah i got you so first lrad stands for long range acoustic device it was developed for the military to send loud long-range messages either through a microphone or pre-recorded and to work as a crowd disbursement tool it does crowd disbursement by playing a very loud set of sounds that are at a decibel count and a frequency that can be disorienting and downright harmful to humans we're talking loud enough to cause someone to become disoriented confused giving them temporary or even long-term hearing damage and if you've been exposed to it long enough you can actually experience blood coming out of your ears and there are a few ways that you can mitigate this and protect yourself against it but first i'm going to show you an lrad and while they have different sets of sounds depending on the model of lrad they use this way you can actually see what one looks like and hear what it sounds like so this is your headphone and volume warning it's going to be about a five second clip coming up next

[Music] all right i'm not going to play that sound the rest of this video so you can go back to headphones a normal volume now but that's what they look like and they're going to be mounted on top of vehicles as you can see from the hands on each side there's actually a person there focusing the direction in which it goes and how effective this is against you depends on a few different factors like i said it is directionally focused so the person operating it has a viewfinder and crosshair so they can aim the device but you can use that to your advantage

if you're off to the sides or even behind it while you will still hear the sounds it will not cause as much disorientation or damage but the decibel levels are still loud enough that you may still get the ringing in your ears so that means one of the main advantages for you in defending against this is distance and direction the further you are away from the device the less it's going to affect you but that also means since it's directionally focused when you see it and they start activating it don't just turn around and run straight away from it treat it like a riptide in the ocean

if you're running away from it you are still in the directional path of the audio waves you want to first run perpendicular to it to get out of the line of fire and then you can retreat a solid material can help block some of the sound waves you want to find cover get something between you and the device such as a wall if you think one of these devices is going to be used at a protest you're going to you need to bring hearing protection and you wanted the highest decibel rating that you can find cotton balls and noise cancelling headphones will not work noise cancelling headphones cancel out different frequency than what lrads operate on so no bows once they bring this out they're not going to stop using it until the crowd's fully dispersed so this is where pre-protest planning comes in before you start protesting you should have designated fallback and rally points not just for the protest as a whole but the group that you specifically came with and not just one multiple that way when this device comes out you can fall back to the predetermined rally point regroup and plan how you're going to proceed to continue your protest
