I thought this was ADS since I can’t hear the sound in any of the videos of this protest I’ve seen, like in this LRAD video and in this LRAD defense video its super loud.

So I don’t think headphones would help here since ADS just heats the water in your body but a riot shield would help just on the parts of the body it covers since the ADS can’t penetrate very far, not sure if conventional clothing would work or if you would have to cover your body in something like aluminium foil to stop the millimetre waves penetrating skin.

Edit:

Seems like it was some form of LRAD, the speakers probably weren’t focused on any of the microphones from videos I have seen.

Those exposed to the weapon experience sharp ear pain, disorientation and panic, security experts say.

Many who say they were in the epicenter of the alleged attack complained on social media about strong headache, nausea and disorientation.

More than 3,000 reports had already poured in, with witnesses detailing “a powerful sonic impact, accompanied by a wave of heat or wind”, the organisations said in a statement.Some described the sound as a “deep roar” akin to a jet engine or a train in a tunnel, “combined with a high-frequency whistle, a cannon blast or an explosion”.
