Leave it to researchers at MIT to analyze the effectiveness of aluminum foil helmets on protecting your brain against invasive radio waves. In you read the Onion, you are going love this.

"Among a fringe community of paranoids, aluminum helmets serve as the protective measure of choice against invasive radio signals. We investigate the efficacy of three aluminum helmet designs on a sample group of four individuals. Using a $250,000 network analyser, we find that although on average all helmets attenuate invasive radio frequencies in either directions (either emanating from an outside source, or emanating from the cranium of the subject), certain frequencies are in fact greatly amplified. These amplified frequencies coincide with radio bands reserved for government use according to the Federal Communication Commission (FCC). Statistical evidence suggests the use of helmets may in fact enhance the government's invasive abilities. We speculate that the government may in fact have started the helmet craze for this reason.

We evaluated the performance of three different helmet designs, commonly referred to as the Classical, the Fez, and the Centurion. These designs are portrayed in Figure 1. The helmets were made of Reynolds aluminium foil. As per best practices, all three designs were constructed with the double layering technique described elsewhere (I highly recommend following the 1st link to see these helmets).


The helmets amplify frequency bands that coincide with those allocated to the US government between 1.2 Ghz and 1.4 Ghz. According to the FCC, These bands are supposedly reserved for ''radio location'' (ie, GPS), and other communications with satellites. The 2.6 Ghz band coincides with mobile phone technology. Though not affiliated by government, these bands are at the hands of multinational corporations.

It requires no stretch of the imagination to conclude that the current helmet craze is likely to have been propagated by the Government, possibly with the involvement of the FCC. We hope this report will encourage the paranoid community to develop improved helmet designs to avoid falling prey to these shortcomings.

Thanks Robert

sounds like the conspiracy theory behind LSD.
May be these aluminium helmets are potentially as dammaging to the brain as the good old acid lysergic molecules. However in this case, we can even speak of "pre-effects", given that you must be already seriously infected to start using those helmets.

A Nuerophone can be heard by way of the inner ear and not the outer conventional ear, in fact if the signal can make contact with your skin you will be able to hear it and just the same for any other person in the room,

so may i assume the worlds security and military forces can technically communicate with the targeted individual as long as that signal can make physical contact with their skin ?

so any defence must be in the outer garments ? extending from head to feet,

I am currently trying Steel Wool, this is used in wood work as an abrasive, and usually bought in rolls, Steel Wool will prevent light passing through it when three layers deep,

( no need to twist it into a rope shape in order to achieve a higher density as i did as this simply makes more work when you can just take it from the pack and make those three layers ).

it can be used as a padding in jackets and hood linings and shoes and you would have to make lengths to make a trouser lining, it can be compressed to be quite flat,

may also be tried in blankets and pillows and curtain linings. and im sure there are many many places i have not yet thought of, all the best peebs :O).

Plausable deniability. Cover your covert band with a seemingly rediculous notion that wearing tin foil on your head blocks mind control beams. When you find intelligence agencys involvement the weirder the more plausable that it has some truth to it. Like the movie Ruby stated. These guys do stuff that doesnt make any sense, so if you rat on them, YOU come out not making any sense.

To ben demps: there are classified frequencys by the us government and military. Here is one many dont know about:

You've heard of UHF silent subliminals. The health frequencys are 14.8khz which have an interesting antagonistic effect on ELF waves. You can feel something going on. What this presence is is another thing. But the military used 15khz. Because 15hz bypasses the ears to resonate with the audio cortex. 15hz is too low to play with any loudspeaker, but 1000hf degrees in magnitude seems too have a similar effect. Ditto with other psychoaucoustic frequencys. The same goes for harmonics. So 300hz bypasses the subconscious belief filters. Often played as a droning tone accompanying a vocal track. Dooooooooooooooooooooooooo. You can also modulate it at 3.5hz (adding 303.5 hz) for a double whammy. A kind of a rolling doooooooooooooo sound. The subconscious filter is a big barrier in human psychology and thus in conditioning. Constant bombardment could have a little known pavolovian contrary effect. The usage of people who are primed for conditioning of course would be people already with a tendency for schitzoaffective disorders or who are currently "schitzo".

I assume this was intended as humor, along the lines of the microwaved peeps and high velocity egg experiments, but...I notice from the pictures and commentary, they never GROUNDED the helmets.

Of course this isn't going to stop anything. Any wave energy collected by the foil is going to be directed directly through their body. Just as their experiment confirmed.

This is fairly simple stuff. Probably most of us have made aluminum foil antennas for television sets at one time or another. The whole 'tin foil hat' thing seems to be used mostly as an expression to dismiss people and ideas as ridiculous. Only a 'crazy person' would wear a tin foil hat, right?

But is it crazy to make a television antenna out of the same?

Of course not. Now, granted, whether or not the transmissions of *modern* mind control technology can be redirected or reflected by such crude means is subject to question...but honestly, if you're hearing voices, waking up with dizzy spells, or generally feeling odd compulsions to do things that are out of character for it so unreasonable to take five minutes and give the aluminum foil a try? Somewhere private, where no one will see?

Just remember to properly ground it, or you may end up focusing the waves, exactly as reported by the people at MIT.
