DEFEATING LRAD

We test a few different methods for protecting yourself against an LRAD system.

Nothing - 3:54
Earplugs - 4:50
Standard Headphones - 5:54
Electronic Headphones - 6:46
Face Shield - 8:21
Riot Shield - 9:23

Putting earplugs into your ears correctly is actually a skill

[mrclown]

You should have tested the Wile E. Coyote technique of using a U-shaped pipe to beam it back at the operator.

[BooDamnHoo]

Something to keep in mind: in the air force the jets I operated on could produce sounds in the 150+ dB range. EXTREMELY loud. We would wear the ear foam inserts AND headphones together. That works well.

[TheJoeman]

I love the idea of reflecting the energy back to its source when the energy is being used without justification.

[MakeItorBreakItNow]

how about foamies + headphones? That what we use in the Navy around loud aircraft.

Ah quality father son bonding time, testing weapons of war on each other.
=P

[DarelGabriel]

Thank you ! 
It's very helpful to know how to protect yourself from the government when engaging in legal, constitutionally-protected activities.

[RobertGallop]

You’ll never please everyone! But most of us appreciate the work and dedication you all out into each video to keep information ‘open’ that would otherwise not be. Your unique facility and access to materials and tools is something most of us don’t have easy access too. Thank you for what you do!

[sidraket]

politics? ive always considered you a low key agent of chaos, ensuring everyone can have jet powered smoke screen deploying laser drones. most delightful

Knowledge is neutral, neither good or evil. Like you, and I am sure the other people watching your videos, I am a curious person. I like learning about lots of different things, even if I don’t intend to do anything with that knowledge, other than satisfy my curiosity. My day always get a little better when I watch or even re-watch on of you videos. Thanks

A retro reflector is made of three mutually perpendicular surfaces. (inside corner). They are easy to make and could make awesome LRAD armor or shields, because they reflect back at the source. I mention this because flats are probably easier to come by than curved sections.

[Conlan]

Plot twist: He was only able to get closer after each test due to severe hearing loss.

Imagine the police is trying to shut down a demonstration with LRAD and the crowd starts unfolding dozends of parabolic reflectors with UNO Reverse cards painted on them xDDD

[ThatBastardSnow]

G'day from Australia.
Thank you for doing this research. It seems to be vital today more then ever.
I'll be sharing this video.

Next Video, combine the LRAD with the fog machine from a few videos ago. Would love to see if the sound pressure produces some visible effects in the fog clouds. If so, maybe you could even see the waves bouncing off from the riot shield?

[pseudonymity]

That's good to know that you can use a reverse riot shield to defend your self from a LRAD, and also reweaponize it for your own defence in the case of being assaulted by such a weapon during a peaceful protest. I would say that having a PPRS setup (Plugs Protectors Reverse Shield) would make this useless, and counter productive for the aggressor.

[LazerLord]

Walk softly, and carry an LRAD
But TBH, no one would know if you walked medium-loud.

"I can demonstate how to throw a punch-" [goes Super Saiyan]

[danielcarter]

In the Navy we were "required" to use double hearing protection when around jet engines ie: foam plugs as well as head set, gel ear surrounds work better than the foam ones.

Having a dad like this must be incredibly nice, to say the least!
