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

        Sound is moving air and carries energy. With the right frequency and intensity it could definitely physically fuck you up even if your ears are covered.

        Wikipedia:

        Studies have found that exposure to high intensity ultrasound at frequencies from 700 kHz to 3.6 MHz can cause lung and intestinal damage in mice

        Nope. It’s a sonic weapon, not loud speaker.

          LRADs are loudspeakers. Loudspeakers which can output in the order of 160db at 1m. Anything can be a weapon when you make it powerful enough.

            Technically, yes. A bullet is just a fast moving object.

            I was refering to sheer power of the thing. Guy asked if earplugs would help. LARD gets a tree swinging. It’s not “just a speaker” at that point.
