A device that silences incessant talkers or mutes people who talk too loudly has been created by Japanese scientists.Dubbed the SpeechJammer,The gadget has been devised by Kazutaka Kurihara, a researcher at the National Institute of Advanced Industrial Science and Technology, and Koji Tsukada, a professor at Ochanomizu University in Tokyo.
The hand-held device consists of a microphone that it pointed at the speaker and records that person's voice. It then transfers the sounds to a speaker and replays them back in the same direction with a delay of about 0.2 seconds.
The microphone and speaker are directional so the device can be aimed at a speaker from a distance, like a gun.
"The system can disturb remote people's speech without any physical comfort," the scientists said
