Shut up machine

We have all faced at one time or another to people who speak terribly strong in a place where they should not do: the sucks on a train who thinks that if he shouts into his cell phone, it may be able better reception when you try to nap for example

And sometimes even if you do tell them, this does not always discourage them from continuing their noise ...

But a handyman explains how we create our own reverberant sound gun, which will immediately soothe the most stubborn of talkers

The principle of SpeechJammer is simple: it is very difficult for a normal human beingwhile intending to discuss his own words, offset by only a few moments.

The unit is equipped with a directional microphone that will capture the words of a personat one point very clear, and a directional speaker, which will broadcast the sound to your target, its neighbors did not hear the words absolutely broadcast.

                                                 

               Seriously we need this speechJammer in home,work ,school ...... :D
