It's not the first crowd control tool to use sound waves, but Raytheon's patent for a new type of riot shield that produces low frequency sound waves to disrupt the respiratory tract and hinder breathing, sounds a little scary.And like Roman soldiers joining their shields to form a large impenetrable wall, these new riot shields can actually be networked together to form a larger acoustical horn, vastly improving their range, power, and effectiveness. There's no word on what the long-term medical implications might be if you find yourself on the wrong side of one of these shields. But I imagine the unpleasant experience is not unlike being force choked from afar by Darth Vader.
