I guess it's a shield from the conductive properties....

Robbie,

Correct, the YShield paint is electrically conductive. Painting over it only has aesthetic effect. But if you prefer coal-black walls, you can always leave it as-is ;-)

Hello,
Recently I`ve purchased and installed in my room stainless-steel gauze HEG03. Since the installation the level of radiation coming from the outside has decreased significantly, nevertheless inside the room now I can hear a kind of a whistling noise that is disturbing me especially at night when the house is silent. The shield is connected to the house grounding system.
Is it possible that this kind of shielding can cause this type of audible noise inside a room?
Thank you in advance for your answer .
With best regards,

Artur

misiek73,

Only thing I can think of is that there's an air draft that's being forced through the tiny masks in the gauze, causing a high-pitched sound.

Its a wild guess.

-> misiek73:

What kind of house grounding system are you using?

Depending on your electrical installation leak currents from other parts of the installation can be transferred to the protective earthing conductor. Depending on the frequencies of such leak current it is possible that the grounded faraday cage acts as a loosely tuned antenna for the frequencies in the leak current which resonates with the faraday cages eigenfrequency (or hamonics thereof). This resonance can be converted to acoustic signal by electrophonic phenomenon.

There are at least two ways one could determine whether such effects are causing the noise:

Simple:
Disconnect the grounding conductor from the faraday cage to the house grounding system and attach it to a new (neutral) earth electrode placed at least several meters from the house grounding systems earth electrode.

(note: Assuming an otherwise sound installation such procedure will not put you in any kind of danger; but it *might* be a violation of local electrical code.)

Technically correct:
Measure the dominant frequency (and its harmonics) in the house grounding system (for instance with a digital oscilloscope), and test (via a tone generator and a suitable amplifier) whether the noise can be experimentally re-created.

1. Many groundings do contain dirty frequencies: from 5kHz up to 10, or even 30MHz.
The walls do pick this up and start radiating it into the room.

2. Be aware thet biologically, thye longitudinal waves are more harmful than the measurable transversal waves.

-> Charles:

Yes, foreign frequencies are a common occurrence in grounding systems, however misiek73 did not state the type of grounding system used. It makes significant difference in regard to mitigation strategies (and the occurrence of leak currents) if the grounding system is TT, TN, TN-s, etc

I am a bit puzzled by the last paragraph in your post...

By longitudinal waves I presume you are referring to sound waves, as there (AFAIK) are no longitudinal solutions of the Maxwell equations in a vacuum. Sound waves (and seismic P-waves) are (as far as I know) the most normal occurring longitudinal waves.

Why do you think such sound waves are more harmful than the transversal (electromagnetic) waves with the vast array of scientific evidence documenting the bioreactivity of such electromagnetic fields???

Guy Hudson here. I have worked out what works for me.
Yshield paint, providing you follow the instructions, works well at reflection-shielding emf's. It also rarely seems to cause problems for multiply-chmeically-sensitive people which is quite an achievement.
If you paint walls, floor, ceiling, doors and foil on windows you have a Faraday cage. Because it all reflects, any radiation causes multiple internal reflections. Cyril Smith noted that his ES patients in a Faraday cage would radiate signals due to their disturbed immune systems and zap themselves.
He used plastic water carrying jerry cans with rock salt in them to dampen this radiation down by absorption.
I recommend reflective wallpaper as a first layer - quicker and easier than 5, 6, or 7 layer of paint.- Yshield sell some (new product), or aluminium backed paper, continuously connected and earthed to the mains earth or to a grounded earth on the same earth system as lightning conductors. Great care needs to be taken not to bridge to the electrical earth if you are using this system.
On top of that I recommend ABSORBING wallpaper from my website http://beneficialenvironments.co.uk/product/emf-shielding-wallpaper/
(I sell it because it works for me - I am ES) which dampens the reflections down and also makes it more feasible to only have to do shield less than all 6 surfaces.
Y-shield paint is useful for the cornices, architraves and windows and doors which the wallpapers won't cover.
nb the aluminium backed paper is not suitable where any hint of dampness is around becuase it stops the wall breathing and mould is famous for upsetting ES/MCS sufferers.

the whistling may be microwave hearing on your part - does anyone else hear it, too? Because if it is onlt you then you need extra shielding close to you.

Hi, could you explain this a little more? ie how much to fill the cans with water and.or rock salt, and where best to place it in a faraday cage?

Thanks!

Do you have any tests of the attenuation properties of the material? A test made after ASTM D4935-10 tells a lot about the properties of the material.

BTW, you write on you homepage that the absorbing wallpaper must be grounded. As such I suppose it is electrically conductive, which usually means that the material will have some reflecting properties along with any absorbing properties.

What material is the absorbent wallpaper made of? Carbon/graphite??

Is the absorbing material dispersed in the wallpaper in such a way that it will absorb regardless of polarization?

Water - with or without salt - is a really good absorber of microwaves. This is probably the main reason that this site exists...

BTW... The dielectric properties of water actually drops as you add salt (NaCl).

I'm not very scientifically minded, but I'm keen to try a can of rock salt and water and see what effect it has on my shielded area. I am one of those people who is probably zapping themselves at times due to a combination of high EMR levels and auto-immune dysfunction.

Note that the water only absorbs the microwaves that actually hit the water. It does not lower the the overall intensity in an area.

But strategically placed containers of water can be used to dampen reflections - but it requires quite exact placement.

As I noted in an earlier post the dielectric properties of water actually drops as you add salt (NaCl). This means that the best dampening properties is achieved without adding salt.

As to the size of the containers: Large enough to cover imperfections in any existing shielding enclosure, or large enough to substantially shield by themselves. The water ONLY absorbs the microwave which actually hits the water.

Thanks for the extra clarification - I sometimes find it all hard to absorb, if you'll excuse the pun.

I had the same problems with HF54 paint. Already while painting I felt strange and tense. After covering it twice the direct impact got less. But after the second night I started to get heart and severe circulation problems. Just last week the carpenter was there to remove the whole wood wall...

I'd rather be cooked by the nearby antennas then decay by HF54

(Our next try will be with steel net, if it won't function, we will at least not destroy the house.)

Sabine,

Have you previously experienced reactions to water-base paint? YShield is water-base.

For the paint to gain full shielding capacity, it needs to dry completely (evaporating all the water).

What country are you in? Some countries have different exposure guidelines.

Hello Henrik

thank U for replying. No, I never had any kind of reactions like I have experienced with this HSF54. Actually, I feel quite good with paint since I am an art teacher and in contact with lots of paints and materials.

We live in Switzerland.

First, I thought that it could be the smell of the colour itself, but the problems began the second night and stopped only one night after it was removed.

I think somehow the "tension" in the room changed (not in the sense of HF). That sounds maybe little bit strange, but I think that such a big surface of graphit is unusal. Diamonds are said to give you power and energy. Just emagine a whole wall of diamonds. You don't want to sleep there.

I have also heard that people sleep bad over filled oil tanks (in the cellar).

So, I think - beyond the discussion of HF and LF that started only 15 years ago - materials have a bigger impact on health and well being as believed.

It is sad enough that one must protect himself with "crazy" things like all kind of metall clothes, graphit walls and other stranges materials to the body.

WHAT A TIME WE ARE LIVING IN ?!?

"Just emagine a whole wall of diamonds. You don't want to sleep there."

That's not a valid comparison. Graphite powder mixed in a water-base and painted on to a wall does not equal "wall of diamonds".

Agreed that the situation is absurd - that one must employ special technical fabrics and paints to reduce ones fully legal exposure to a potential carcinogen.

Sabine,
did you only paint one wall? That could reflect any emfs that reach it and increase their effect because they don't dissipate.
As for working with paints and seemingly be OK sensitivity can develop at any time during high exposure.

Hello Anonymous

Yes, I had only one wall painted, because the electrobiologist that was there, measured that from the back nothing was coming in.

Now I gave the same wall a new try and shielded it with steel cloth. Since more then a week now I have a normal sleep again and all the problems with my heart and apnoe has stopped the second night after I removed the graphit wall.

Maybe I would use HSF 54 only for outside the house, but not for the inside again.

My question: has anybody experience shielding a house outside with HSF 54?

Hi Volker/Hernik,

Is the paint always 90% reflective or does grounding redirect a higher percentage to the earth reducing the reflectivity rate?

I can thoroughly recommend the shielding paints from Yshield.

I have extensive experience with HSF44. HSF44 and HSF 54 are rather similar in regard to shielding effectiveness, however HSF44 are are somewhat better choise for external application. You can achieve very significant exposure reduction if applied in a manner appropriate to the structure one intend to shield.

When constructing a faraday cage (which a HSF44 painted house essentially is) one should be aware that any imperfections in the shielding enclosures will have a different impedance than the rest of the structure. If the shielded frequencies (and harmonics thereof) somewhat resonate with this impedance some of the shielded RF-energy can be re-radiated from the faraday cage. Mitigation of this unwanted characteristic of a farady cage is usually done by thorough grounding.

It should therefore be noted that grounding, although essential to remove re-radiation as descibed above, in itself does not increase the shielding properties of the faraday cage.

Furthermore the quality of the grounding installation is quite important. If situated in an area with higher than usual conductive properties in the upper layes of soil one can experience a situation where leak currents from other parts of yours (or neighbours) electrical installation can be transferred to the protective earthing conductor. Depending on the frequencies (and harmonics) of such stray current it is possible that the grounded faraday cage acts as a loosely tuned antenna for the frequencies in the leak current which resonates with the faraday cages eigenfrequency (or hamonics thereof).

As such it could be appropriate to check the grounding possibilities in the area before commiting to a sheilding strategy which is dependent upon such grounding.

Hi Kim.
Merry Christmas and a Happy New Year to you.
You address your letter to Volker as well as Henrik.

Volker worked for Yshield some years ago, and he was a FIND for Mast-victims as he, after I asked him only once, followed MV Forum and when someone asked about protection he would give us the REAL Facts about what to do, what to expect, how to earth, and so on, he was truly knowledgeable and so prepared to help everyone needing help out.
And yes, he was a Yshield salesman, put in links to their products, but his advice on Forum was invaluable to us.
Since he (of reasons unknown to me) left the Yshield company I have tried
to get them to help us out, Christina gave a tiny bit of info, but under Deep pressure from me, and she never followed up on questions asked after her posting which made her postings worthless to all,
We deeply miss Volker, and wish he would come back to Forum with his great knowledge of protection against this environmental pollution catastrophe.
But at least we do have you and Henrik to help us, not professional like Volker, but the most informed people at this Forum today.
All the best to you two, and truly thanks for your good advice in 2015.
May we get "Smart" and win some upper hand (even in a small way would help) in 2016.
Best regards.
Agnes

Hi Kim,

Thanks for your detailed answer about the grounding. I have a few more follow-up questions:

1) If I painted only one exterior wall to deflect a point source near it and not trying to achieve a faraday cage effect, does grounding matter?
2) With no ground, if I have two layers of latex paint, and someone drives a nail and hits an electric wire, will the entire surface now conduct despite the layers of latex paint and become a safety hazard?
