Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Does anyone know if noise cancelling works against or diminishes this sound?

[–] catloaf@lemm.ee 16 points 6 days ago (1 children)

No, your airpods will not protect you from this. Not only will the sheer volume of sound overwhelm their tiny ANC speakers, but sonic weapons affect more than just the eardrum. They can affect your heart, lungs, and other organs.

Exact right, as it's untrasonic, the sound is transmitted directly through the target's body. Noise canceling earphones/plugs will have no protective effect whatsoever.

I watched a video after this happened where a guy was testing defenses. He tried what he called electric headphones that I'm guessing are noise canceling, and they made it worse. Best defense was ear muffs and a riot shield.

No, the sound is transmitted through the body rather than just via the auditory system in such a way that simply plugging or covering your ears will provide no protection from the effect. As analogy, imagine the effect of a train whistle or jet engine on someone who's within 1-25 ft., but 100% deaf. It wouldn't need to be heard by their ears per se as it would be so powerful as to be transmitted into the target's body, which would reacts accordingly to a 100+ decibel sound.

Absolutely not 🤦‍♂️

This just in: wearing noise canceling headphones to a protest is now illegal.

[–] Redditsux@lemmy.world -4 points 6 days ago

I would think it provides some protection.
