How to Build a Speech-Jamming Gun

[MindMover]

The drone of speakers who won't stop is an inevitable experience at conferences, meetings, cinemas, and public libraries.

Today, Kazutaka Kurihara at the National Institute of Advanced Industrial Science and Technology in Tskuba and Koji Tsukada at Ochanomizu University, both in Japan, present a radical solution: a speech-jamming device that forces recalcitrant speakers into submission.

The idea is simple. Psychologists have known for some years that it is almost impossible to speak when your words are replayed to you with a delay of a fraction of a second.

Pump Lush Rimbaugh's audio into his "cans" with a second or two delay.

4. Hack your own at home - easy

Item 1 - directional microphone

Item 2 - 200ms delay

Item 3 - portable amplifier

I don't actually recommend this combination - three random items off the internet. It just illustrates how easy it is. A hacker can make all three components, but a cheap guitar delay can be had for $20 - why bother?. A super-directional mic might be worth making.

Nearly anyone in a band, on the other hand, can probably chuck the thing together in ten minutes.

The bigger the amp, the better. A death metal concert PA is ideal, but not terribly portable.
