I've been seeing all these mentions of LRADS and I have a question...

[TheMightyFavog]

Couldn't protesters counter the use of an LRAD by wearing simple industrial/shooter's earplugs or earmuffs available at any drugstore or sporting goods store?

1. ear plugs reduce noise, but don't eliminate it.

They have a harder time with lower tones, too. I think ear plugs, or the ear muffs that airport tarmac staff use can reduce the noise by about 30 db. Which isn't much help if the LRAD is running at 151 db.

2. Yes, unfortunately even battery-powered noise-cancelling headphones

may not be effective at those levels, which easily and permanently destroy the subtle mechanisms of the ear.

Sound guy, here, apoplectic about this.

3. No, not really

And this crap it's not hust what is in the audible range. It also creates a pressure wave...I wish I did not know this crap
