This one is pretty interesting. If you'd heard about noise canceling headphones, you might immediately jump to the conclusion that this gun produces the same effect - offsetting sound waves that cancel the entire effect of a sound. Of course, humans have way more ways to make them silent, and this Silence Gun is a completely different tool.
The silence gun works on the mind. It takes sound and replays it .2 seconds later. That causes your mind to hear an echo of your own voice and pay attention to your words. They sound strange, and BAM! You quiet down because your brain is really really confused. The device is a psychological weapon that attacks the way you experience reality through one of your senses.
The idea of attacking (playing with?) how a person experiences reality is nothing new. Stereograms allow you to focus your eyes and have your brain pick out an image. I also read about a handy way to reduce the pain of a cut using a telescope or binoculars. Unfortunately the silence gun can be used as a weapon... Now I have to develop a sound-canceling gun to point directly at the silence gun to prevent my voice from being silenced (1st amendment anyone?).
