My first Blinky!

WOW! Just like in the movies.

now I am slowly moving to the door, trying not to make any sudden moves

Yup, just like the movies. One of the first things they'll do is your profile. This includes a rough round about figure of your IQ. Then they'll drug you up on mind manipulating substances and attempt to infiltrate. Believe me when I tell you; your girl friend or wife could indeed be a secret service agent. Your boss might even be one too!

Come to think of it , strange things have been going on....

The thing that has impressed me the most is this gadget they have. I dunno what you'd call it, but what it does is project sound from a distance. When I say a distance I mean a long way, few hundred meters or so. Typically they use it to project voice, and this thing penetrates through most matter including; glass!, gyp-rock walls! Don't confuse a megaphone with this. It's entirely different. I get the impression that, once the projected acoustics hit an object that is not penetrable, or it looses range - that's when you hear the sound. It hits the object, boom! - this energy explodes and translates into audible sound.

So, for example, if there's 2 people standing 500 meters apart - (we'll call these two people a & b respectively) - and there's a 3rd person in between them, person a can use this contraption, pointed at person b's head to transmit their voice to them, all with the person in the middle being none the wiser! I did a bit on sound & acoustics at Tafe many years ago, this thing has me baffled as to how it works.

Any thoughts?

I've heard of something like this. The application I heard about was for advertising purposes. eg. You walk by a soda machine and you can hear a fizzing sound, triggering you to think...."hmm, a soda 'sounds' good about now". You turn and look, and to your amazement, there's a soda machine sitting there waiting for your money! Not sure how they do it either.... probably has something to do with flux capacitors, dingle arms or gertle springs.

Flux capacitors?, like the ones from Back-to-The-Future? lol ...
I think what it's doing is projecting a quantified amount of energy (call this the carrier) - and riding a long side this energy is the audio (or at least part of it). Similar to RF, we have a carrier and the audio modulating it, but instead of an electrical receiver, we have physical matter to do the same thing at receiving end. My guess is that, the carrier is just a huge mass of power. This thing is highly focused and can be used with incredible pinpoint accuracy. I have been standing in a crowd full of people with this thing projecting voice into my ear and no one else around me hears a thing.

(And no I'm not nuts, my psychiatrist assures me)

Yup, that's it!!!
