PLAYTHINGS OF THE GODS
ULTRASONICS
If you are in a room with loud music, you will notice that liquid in a glass is vibrating. Also, if youtouch the wall or some solid thing, you will feel vibration. So, we know sound waves affect things intheir immediate environment. When things in the vicinity of a sound source vibrate, you can analyzethese things and reconstruct the sound which caused the vibration.
Now, please refer to the above schematic. There are common devices in almost every home. One is theTV set. In the TV set is a very stable crystal oscillator on a frequency of 15.575 KHz. Some people canhear this high pitied "whine" coming from the TV. This frequency creates an ultrasonic field whichcovers your house and extends beyond the walls of your house. When you speak, the sound waves fromyour voice interact with this known [fixed frequency] field to create an interference pattern. Thisinterference pattern can be detected by spy satellites and, from it, the voices in the room can bereconstructed. This is how the government listens to you in your home when it wants to.
Now that you know this, you can jam the spy equipment by installing "trashy" ultrasonic generators inyour house. Try to find old ultrasonic bug repelers at a flea market or second hand store because thenewer models have been "fixed" so as not to interfere with the spy equipment. This will produce somany random ultrasonic fields that the spy equipment will not be able to lock onto a stable pattern andso will not be able to reconstruct your voice.
