Belgrade authorities have used sound weapons on the crowd of protesters. The video description has some educational links.

There are lots of videos around.

    Honestly, we avoided a massive tragedy at that moment. People described that it sounded like a car or airplane was coming at them at full speed, so they instinctively ran away from the roads. People further away didn’t see or hear anything, they just saw a crowd running in panic and so they ran as well. I was maybe 50-100m away from where it happened, and all we heard was noise, yells, and then people running, so the people around me also started running, but we all stopped after maybe 5s.

    A lot of people think that our overlord wanted to cause a stampede which would lead to thousands of injuries and just chaos in order to discredit the protests. Or maybe they wanted to launch the cannon after the 15 mins of silence were over, which would cause mass confusion since nobody would have any idea what was going on, but triggered it early. In any case, the psychopath used an illegal weapon to attack people literally standing still and being quiet.

          “Let every dirty, lousy tramp arm himself with a revolver or a knife, and lay in wait on the steps of the palaces of the rich and stab or shoot the owners as they come out. Let us kill them without mercy, and let it be a war of extermination.”

            My understanding of this is that it is caused partly by bone conduction. It might be possible that closing your ears by pressing frimly on your “tragus” or on the “mastoid process” could reduce the associated effects. The mastoid process is where the jaw meets the ear.

      Fortunately once people are aware of such tricks, they won’t be effective anymore
