      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.
