Defeating LRAD
By Tech Ingredients
We test a few different methods for protecting yourself against an LRAD system.
Here’s what others had to say:

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

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

Remember: the non-engineer asks, “Could you build me an amp that goes up to 11 instead of just 10? That would be cool, I’ll pay good money for that.” The regular engineer says, “The scale doesn’t matter. It just comes down to wattage and efficiency.” But the great engineer says, “I think I could build one that goes up to 12, but it’ll cost you.”

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!

The combination of earplugs and a motorbike helmet with the visor closed would probably also be pretty good.

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

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

Regarding electronic headphones, some of them are frequency-dependent in their protection triggering (“gating,” to us audio nerds). Given your LRAD is outputting sound well within the peak speech band, and the headphones are tuned to pass speech through, it could explain why they behaved unexpectedly. Also, I’d love to see an acoustician chime in on this subject of deflecting high SPL. A riot shield has its uses, but it would probably not serve well at a concert, for instance.
