Someone who is directly in the loop will probably laugh at this.
However, for us mere "mortals", learning about the latest technological achievements is often a real miracle and a very fascinating knowledge.
I have always been interested in the advanced technology of "eavesdropping" or to put it more politely; expanding and improving human senses with the help of advanced technology.
The latest (to me) eavesdropping devices work on the following principle:
1) Sound is a vibration
2) While talking in a room; our speech is a vibration that spreads through the room
3) Vibration affects surrounding objects and materials
4) The glass on the windows "vibrates" to the rhythm of our speech
5) These vibrations are "picked up" and demodulated with a special "laser receiver".
In this way, the range of "eavesdropping" is drastically increased and there are practically no limits.
The limits are defined only by the quality and level of laser "reception".
One would immediately think of a directional microphone. No, this has nothing to do with any microphones.
A very strong, directed and focused laser beam is directed at the window glass and the ultra micro vibrations on the glass cause the returning laser beam to change slightly, delaying the rhythm of the "modulation".
Selectivity is achieved by additional "sensors" (a wide range of choices) that will "subtract" all other surrounding sources of vibrations from the vibrations of the glass caused by speech in the room.
The quieter the neighborhood around the window glass; it is possible to achieve a greater listening range.
It is easier to listen to a speech in a hut in the middle of nowhere than in the center of a noisy urban place.
Who thinks that he has hidden in such a place, far from urban areas; that only allowed the eavesdropper to easily listen to him from a much greater distance.
How to defend yourself? Play loud blaring music with lots of singing in that room. Add recorded speeches from a medium. And then talk more quietly in that room.
People, however, out of ignorance, do everything the opposite! Ha, ha, ha!
When they want to hide from eavesdropping, it is common for them to go far into the mountains, to some hut, whispering secrets in absolute silence.
