It ’s not the first bunch ascendance tool to employ levelheaded waving , butRaytheon ’s patentfor a new eccentric of saturnalia carapace that produces downhearted frequency sound moving ridge to break up the respiratory tract and hinder breathing , sound a little scary .
Crowd control condition tools like theLRAD Sound Cannonemit burst of cheap and annoying sounds that can induce headaches and nausea . But Raytheon ’s non - lethal pressure shield creates a pulsed imperativeness wave that vibrate the upper respiratory parcel of land of a human , hindering breathing and eventually incapacitate the target . The patent indicate out that the sound wave being generated are in reality not that powerful , so while protestors might collapse from a want of oxygen reaching their brainiac , their eardrums wo n’t be damaged in the process . Phew !
What Is the LRAD Sound Cannon ?
And like Roman soldiers unite their shields to take shape a large impenetrable wall , these new riot shields can really be networked together to form a tumid acoustic car horn , vastly improving their range , power , and effectiveness . There ’s no Holy Scripture on what the long - term medical implications might be if you find yourself on the wrong side of one of these shield . But I conceive of the unpleasant experience is not unlike being force-out suffocate from afar by Darth Vader . [ Google PatentsviaNew Scientist ]
