'Silence gun' developed in Japan

Japanese researchers have come up with a gun that forces anyone that it is used on in to silence.
The device is based on the concept of delayed auditory feedback, when it is used on someone it will replay what they are saying back to them but with a tiny 0.2 second delay - this response offset is enough to completely confuse the brain and renders the individual unable to continue speaking.
Ever since humans first invented guns, they've been inventing new uses for them. Some shoot bullets; others shoot lasers. But a strange and unsettling new gun being developed by Japanese researchers shoots sound waves in an effort to disrupt and silence anyone who dares speak out of turn.

I sometimes get this effect when calling Ireland (weirdly, only Ireland) from my work phone for some reason. When I first noticed it it did actually stop me from talking, but you quickly adapt and learn to ignore it

Did they realise real guns can already do this and the results are more permanent...

How is this awesome? This will not be made available to the public. It's obvious that the purpose is for police or government control. There is no way in hell that this kind of device would be made available to the public, it's power is equivalent to a tank or other military technology. If ever there was a physical object which represented the hierarchy that exists to displace any notion of fairness or equality in human conduct this would be it. So now instead of hauling you off to some psychopathic medical facility to stitch your mouth shut a machine can now replace such methods, oh the wonde... [More]

If you've ever worked with digital recording equipment, you might have come across latency during recording. A slight delay of your own voice played back to you through the headphones (Often around 2ms) Never rendered me confused and silent. Its annoying yes, but its not exactly a silence-o-tron. I think I smell something.....what that? yup, thought so,,,,,, BS!

What if you just cover your eyes when someone uses it on you, the feedback can't "confuse" you if you can't hear it.....
