Invented by the Japanese, the device could be used to hush noisy speakers in public libraries or to silence people in group discussions who interrupt other people's speeches. Can I please have one to point at the loony far Left? (Just kidding, I'm for free speech, but you've got to love the idea of this gadget.) As Sweetness and Light notices, it cannot stop people making meaningless sounds, such as "ahhh," that are uttered over a long time period ... which means Mr. Obama and most Democrats are safe.
Kazutaka Kurihara of the National Institute of Advanced Industrial Science and Technology, and Koji Tsukada of Ochanomizu University, developed a portable "SpeechJammer" gun that can silence people more than 30 meters away.
The device works by recording its target's speech then firing their words back at them with a 0.2-second delay, which affects the brain's cognitive processes and causes speakers to stutter before silencing them completely.
Describing the device in a research paper published Feb. 28 at arXiv.org, Kurihara and Tsukada wrote, "In general, human speech is jammed by giving back to the speakers their own utterances at a delay of a few hundred milliseconds. This effect can disturb people without any physical discomfort, and disappears immediately by stopping speaking." (Fox News)
