Bad hearing due to shielding on ground

As we go through the Dirty power Research by Prof. Dr. Magda Havas can already know, depending on the frequency, harmonics of less than 5 millivolt the maximum recommendation of 50GS units for the electrosmog-Exceed loads in living spaces. This means that even very minor disturbances on the crowd will have negative effects on the human nervous system and thus significantly worsen the musician's experience. This means that it is essential to avoid that the ground can radiate interference - that is, it becomes an antenna.

High tension on the ground

As can be seen from the two oscillograms above, if the mains plug is inserted incorrectly, the voltage on the ground can clearly exceed 100 volts. Even when the mains plug is turned correctly, over 100 volts can occur - here approx. 45 volts. But we don't know how strong the harmonics are that are particularly critical, i.e. those above 2kHz.

Any music lover knows that reducing this interference improves the sound, as he phases out his hi-fi system when it is set up - i.e. tests the correct direction of the power plug.

Dirty power measurement on the ground

It can be seen in the upper measurement that interference can be found on the ground in the entire spectrum from 2kHz to 1000kHz.

In order to test the effects of the radiation of the mass, we “cleaned” the mass with a special circuit, see measurements below. The hearing test showed significant changes in the sound without anything having changed in the signal.

The radiation of the ground disturbance through the screen

The question is, what function does the screen have to degrade the sound? The answer is that the screen is an antenna for interference.

For a test we assembled a coaxial cinch cable once with the ground outwards (normal) and once with the ground inwards (inverse). The cable parameters and thus the electroacoustic oscillating circuit with all its frequency and phase influencing parameters were the same.

It was noticeable that in the blind test all people clearly preferred the cable with the mass inside! This is also confirmed by the field measurements. The cable with the ground inside clearly has the lower field radiation (see below).

Phase out is a standard optimization in hi-fi. All medical examinations over Dirty power from Magda Havas show an influence on the nervous system and thus on hearing.

All of our measurements on the ground show the same problems that were raised by Magda Haves. All hearing tests with manipulations on the ground and the radiation to the outside show that there is a considerable sound problem here.

The innovation in HiFi - the massless one VORTEX HIFI Nano Shield umbrella

Vortex HiFi only uses massless shielding technology. So it is possible to protect against mass disturbances of the devices through open inputs and outputs with the Vortex HiFi Nano Shield Plug's to protect. Also the Equipotential bonding can be perfect over the Vortex HiFi Nano Shield cable which are shielded via earth potential.

This field sink around the vortex cable makes it impossible to radiate the interference from the field source mass. The Vortex HiFi cables can be used as universal cables as digital, video, signal and equipotential bonding cables and this without ground interference, as even the plugs with the ground-free Nano Shield technology are shielded.

2 thoughts too "Mass-free screen"

  1. I don't know what to make of all of this. I am an electronics specialist and I am very familiar with hi-fi.
    But I find it difficult to cope with the crowd inside and the signal outside.
    I suspect this could be charlatanism with the aim of getting people's money out of their pockets.

    1. Dear Mr. Gottfried Karenovics, dear readers
      Thanks for your comment. This comment shows 4 facts as an example:

      1. Many people are stuck in old ways of thinking. This according to the motto - We have always done that. And if someone else does it he is stupid or wants to fool others. The field measurement on this side around the coaxial cable clearly shows the advantage of taking the mass inside. The radiated field strength is reduced. The text also clearly describes why we are doing this. We want to protect people from mass disturbances - that is, to reduce the field strength. So there is absolutely no question and it has been metrologically proven that the path we take with the rotated mass is the right one for our objective.

      2. The self-appointed, so-called “experts” do not argue either. They only evaluate and do so on a basis that is not made transparent for others. But since they are supposed to be “experts” it must be true! Why our inverted coaxial cable is exactly wrong for this specific application and objective that we are describing, the "DRAUFHAUER" is silent. This is because these so-called "experts" do not deal with the goals and often only know THAT YOU DON'T DO IT THAT. Why it should be wrong in this case, these self-proclaimed "experts" do not know at all. Otherwise you would enlighten us all and the criticized person could go into it concretely. But since these people have no idea about the specific problem, nothing specific comes up. You could be embarrassed. If you don't say anything, you can't say anything wrong.

      3. Many so-called “electronics specialists”, especially in the hi-fi sector, have a huge problem with adopting a point of view other than a technical one. A technical solution in HiFi has a signal problem to solve - period! For these experts, it does not matter at all how small the signal error is compared to the total error in the transmission chain. Except that a signal error counts!
      Here is a cable example: If a loudspeaker produces a 140 ° phase error at 20.000 Hz, but different cables can only change the phase by 20.000 ° at 4 Hz, “HiFi specialists” have long discussed how to improve this tiny phase error by 2-3 ° and they see it still considered extremely important. How absurd this is becomes clear when you know that the wavelength of sound at 20.000 Hz and 343m / sec speed of sound is 1,7cm. 1 ° then corresponds to a distance of 0,05mm! You read that right 0,05mm. Even different postures when listening to music generate changes in the relative phase through a multi-way loudspeaker by a multiple of the signal error that is caused by each cable! Nevertheless, we hear significant cable differences! The errors in the amplitude frequency response are even more blatant if you compare cable errors and turning your head when listening to music. According to our own measurements of head-related transfer functions (HRTFs) using a dummy head, the frequency response errors are basically never (2-channel consideration) below 15 dB. While cable faults make up tiny fractions of 1dB in the audio sector. The signal-related perspective makes no sense in practice with cables.
      Despite these clear facts, people who go other ways and pursue other goals, namely to achieve an optimal music experience by reducing electrosmog, are vilified. We present tons of facts, such as medical examinations, HRV EKGs and technical measurements that can be traced at any time - as here on coaxial cables - which underpin our point of view.
      For real professionals it would be easy to understand our measurements. On the basis of these concrete facts, one could then start a discussion, at the end of which one would then make an assessment. So do it real Professionals. But for these self-proclaimed "electronics specialists who are very familiar with HiFi" it does not matter how many metrological and medical facts are listed. These are simply ignored - because they do not fit into your worldview.

      4. On the Internet, many think you can simply insult and denigrate people. Mr. Gottfried Karenovics puts forward without any single argument and to go into the facts listed in the room that we are charlatans who want to pull people's money out of their pockets.
      We are a small company that uses a huge amount of our funds to research fundamental relationships. I claim that with over 50% of our funds that we spend on research and development, we are at the top in the hi-fi sector. Our share of the costs for advertising is less than 1%! We don't have to sell our products like warm beer with pseudo price discounts and huge advertising expenses. Our dealers are convinced by conviction! Many of them are musicians themselves and also engineers. One is even a metal instrument maker and he was a professional musician.

      Why are you denigrating us, Mr. Karenovics? I have 2 children at school and my co-worker had his third child a few days ago. What makes you want to harm people you don't know? Before denigrating people, think about the fact that there are real people on the other end who can harm you personally.

      With kind regards,
      Norbert Maurer
