Do you wish you have a magical stick that makes people shut-up? Do you feel sometimes annoyed and you wish you can say “be quiet”?
The two Japanese researchers Kazutaka Kurihara and Koji Tsukada, came up with a prototype for a device that makes your wishes come true and makes people shut-up! According to the researchers, scientifically when “we make utterances we not only generate sound as output, but also we utilize sound actually heard by our ears” in our brain. This process called Auditory Feedback and humans’ natural utterances are jammed when this process is artificially delayed.
The researchers used the idea of speech disturbance by Delayed Auditory Feedback to build their device. The developed a system that can impose strong constraint on speech-based discussion by making speech difficult for some people. They focused on two major negative features of human speeches; unavoidability and occupancy.
The portable speech-jamming gun transmits signals via the air in a round-trip manner between the gun user and the target. The device works by aiming and shooting the target to disturb him/her.
