    Always bring earplugs, ear defenders, and if possible a large, flat rigid object. A sign made of corflute is meh, a big flat book is pretty good.

    If possible, wear glasses and put the flat object between you and the LRAD while it’s going, these can cause ear and eye injuries by vibrating the fluid in your eyeballs. Even a thin barrier can attenuate the sound down to a safer level.

      I was wondering why they turned it off too.

      Totally unrelated, an old satellite dish or really anything concave and hard can be used to direct the sound waves at the emitter/operator. Also, most hard materials can block most of the negative impacts of sonic weapons like this.

        Even better, any old round plastic trash bin can be cut out into a rounded dish that when turned around will reflect the beam, and it can also be held like a riot shield to protect against projectiles!

        (do keep in mind that most jurisdictions would consider you deliberately reflecting an LRAD to be an assault against the officers, and would literally throw you in jail for it, though curiously it’s not bad when they do it directly to you, just not when you defend yourself. Who would have thought?)
