      I still don’t understand. People clear the street very quickly but I don’t see anything like a car or teargas. Does the sonic weapon sound like a vehicle or something like that?

        It actually really simple. High-pitch, high intensity (around 150 Db) sound projected directly towards your ears causes pain to your ears. If you’re close enough then it can permanently damage your hearing. It can also blow out some microphones so many recordings of this from a victim’s perspective don’t actually contain audio of the actual deterrent sound.
