Of course reddit took it down. There’s a decent video on protecting from these systems on youtube; the gist is that normal industrial headphones provide the best protection by themselves, but the protection is even better when paired with a riot shield. I imaging you might even be able to reflect the sound back of you had something stiff and dense.
Thanks for sharing this video! It’s a great resource. $5 shop headphones and a polycarbonate shield you can make for under $100 beats a $20,000-$100,000 LRAD. I wonder if ear plugs, shop headphones, and a shield would be any more effective.
If you are at an action, a set of hard plastic ear protection and a P100 can easily fit into a light backpack. A shield is a bit ridiculous and you’ll look and feel like a bit of knob, not to mention, be extremely conspicuous. If you are still concerned about LRAD, stick some foam ear plugs in before you put on the hard plastic ear protection.
If you insist. I’d prefer the freedom of movement and comfort that not carrying a giant, heavy thing that I’m barely going to use offers me. Also, I’m somewhat less likely to come across as a bellend.
Good advice but the respirator doesn’t wrap around the ears so in the context of acoustic protection/reflection it doesn’t seem effective. I agree that a shield is conspicuous… I’m just spitballing about total effectiveness in theory. I like the end of the video shared above where the concave parabolic shape of the shield (when reversed) was used to redirect the LRAD sound at the operator. Pretty cool seeing a vulnerability in a system exploited in that way.
LRAD is just one threat among many. I’ve been tear gassed plenty of times. LRAD? Not even once. I did however, put on my ear pro several times, not due to LRAD, but due to people throwing fireworks at police and having them go off all around us.

Also, physically destroying the system works too.
Would a breaking bottle of flammable liquid with a flame work?

Just make sure to get the shop headphones. They are hard plastic. And if you are looking to gear up, I would recommend a P100 before a poly-carbonate shield. Something like this: https://www.lowes.com/pd/3M-Full-Facepiece-Respirator-6000-Series-Reusable/1002442040

Polycarb shield only needs to be about the size of, say, a protest sign…

All good info. A bit outside of this post context but helpful nonetheless.
