And I thought the voices in my head were already bad.

I can imagine walking down a sidewalk and being barraged by soundblip advertising from the stores I walk in front of. Or...by their competitors across the street. Un-nice.

Also, what happens if some dumbass kid gets ahold of this and shoots Metallica at 130 decibals at passing motorists? This is a dangerous technology. I hope it gets some lawmaker attention before it gets public.
