Today's article is probably a landmark in this series. We will present our first tangible evidence of the biological effects. As the effects of this system were perceptible, it led to the idea that random rapid movements of muscles would cause pressure, or sound waves. Low frequency soundwaves are felt, rather than heard and this is known as infrasound. Higher frequencies can also be felt, as they are pressure waves.
To test this hypothesis we made use of an electronic stethoscope, connected to a known target and began to listen for sounds that were abnormal. What we were expecting was a collection of pops and clicks as nerve endings fired and small muscle movement were instigated.
We were not disappointed.
An electronic stethoscope is similar to the normal devices doctors around the world use everyday. It is simply a modern version that amplifies the sounds electronically, rather than just directing it into your ears. This allows for direct recording to be made and complex analysis to be performed rather rapidly.
It is important to understand what sounds would normally be expected in the human body. I have found a good series on Youtube everyone can use as a point of reference:
Have a good listen, not just to the foreground elements, but also to the background noise. Try to become familiar with those sounds. A good audio setup is critical here. If you have a cheap on-board soundcard, on either a desktop or laptop, it will not reproduce the sounds with great fidelity. Further, a decent audio setup or headphones is a must. The difference in quality is dramatic. Most important in all of this, is the ability to reproduce the low frequency sounds.
We connected the stethoscope to the neck of the target, fed the output to a 24-bit delta-sigma ADC line-in of a high-end sound card and hit record in a professional wave editor.
This is what we heard.
The first recording is the raw, unedited output from the device. We hear a low rumble that appears to be composed of disceet pulses and a periodic loud pulse in the foreground. Have a listen:
The pulse in the foreground is so violent that it causes physical pain. As far as we can tell, this is peripheral nerve stimulation and propagates muscular motion as it is fired. The sound that can be heard is the sudden motion of a muscle, not an electrical discharge.
The sound in the background is a genetic algorithm hard at work. Although the firings sound random, a program is stimulating nerves to map the structures in the brain and throughout the central nervous system. The genetic algorithm is seeking a functional control system that can coordinate the entire body.
Note that we cannot hear the heart or lungs. This tells you just how loud the effect is.
Next, we run the run the raw sample through a bandpass filter. We can now make out the lungs and get a clearer reproduction of that foreground pulse. Listen here:
Finally, we pass the original sample through a low pass filter. This allows us to focus on the underlying rumble. We can hear clearly now that it is a complex array of rapid pulses, each firing a small muscle group. You can almost visualize a brute force attack being conducted. It should also be clear what exactly I meant when I stated that the system "plays" the body like a piano. Listen for yourself here:
Well, this is obviously not normal by medical standards. For these muscles to fire, they require signals to trigger those events. No known disease on the planet produces such an effect, so we are certainly looking an external source. The only possibility is radio, no other method is physically possible.
So, we finally have some solid evidence and more importantly a detection method, at least for those subjected to physical effects.
