Guns are a great way to shut people up, although they tend to do this by the way of gore and blood, which isn’t cool. That facility now comes in a non-fatal form with this crazy gun that works as a Speech Jammer. Developed at the National Institute of Advanced Industrial Science and Technology in Japan, the speech jammer plays with the way we speak creating an effect called Delayed Auditory Feedback.
Basically, as we speak we listen to ourselves and frame the succeeding words to proceed. This gun throws back what we were speaking at us, with an added delay of a few milliseconds. This delay manages to kick in the delayed auditory feedback, and rails the speaker off to silence.
