How to protect my ears of an acoustic attack?

I think it was EMF too, grape in the microwave kind of thing. Resonance

I should answer your question OP. Your ears have nothing to do with the effectiveness of high power ultrasonic. I've stung myself messing with those ultrasonic crystals and felt it with my finger while hearing nothing. The main reason ultrasonic sucks is air, in water it can travel a long ways but in air 30-40ft would require a incredible emmiter. And 99% of that energy would be lost, it diffuses like ripples in a pond, there is no way to make a beam like with radio waves, well not anything that is a tight "beam". If you want to protect yourself fiberglass insulation will stop the waves in the air because it is basically sound. Just sound. Egg crates would probably be great too. Ultrasonic is sound and doesn't even travel as well as sound we can hear.

5G?

5G towers could be used as microwave weapons but 5G itself isn't that, regular 5G transmission is on a lower frequency

Russian shills confirmed.

IIRC the weapons exploit the Microwave Auditory Effect, so rather than being caused by acoustic waves, modulated microwaves are causing your inner ear to resonate.

The answer is literally tinfoil.

You have to go back, Hillary.

Can you not read?

it probably (probably) wasn't a weapon but eavesdropping tech with an unknown side effect.

imagine rhe amount of power would be needed. its alot easier, quicker, more efficient, and easier to hide to kill you more convential ways for no ones like us like guns and poison. they wouldnt even target us anyways.
