    Good advice but the respirator doesn’t wrap around the ears so in the context of acoustic protection/reflection it doesn’t seem effective. I agree that a shield is conspicuous… I’m just spitballing about total effectiveness in theory. I like the end of the video shared above where the concave parabolic shape of the shield (when reversed) was used to redirect the LRAD sound at the operator. Pretty cool seeing a vulnerability in a system exploited in that way.

      LRAD is just one threat among many. I’ve been tear gassed plenty of times. LRAD? Not even once. I did however, put on my ear pro several times, not due to LRAD, but due to people throwing fireworks at police and having them go off all around us.
