Electromagnetic Bubble?

Hello, I shared an experience with a partner, where while we were laying with each other, I felt a strong, thick physical energy surrounding and or eminating from us. As I was feeling it, they asked me, "do you feel that?". I simply said yes and we did not discuss further. What was it? I know there has to be a scientific explanation. Ive asked others but only received jokes, such as Star Wars references. If there is another, more appropriate scientific forum, I'd appreciate the direction. Thanks so much

High V/m Reading (50-60) Near Window In-Front of Power Line

Does it make sense that if I press the sensor very close to the window glass I get these readings but just a few inches back it goes back to 0 or so? For extra info, the mG measurement is 0.
This is in the kid's bedroom.

Thanks!

[Shielding: Wi-Fi] Polyethylene shields Wi-Fi.

Plastics: Plastics such as polyethylene and polypropylene can block wifi signals due to their high dielectric constant. These materials can absorb or reflect wifi signals, disrupting the flow of data.

Scroll down webpage to:

Material Dielectric Constant Absorption Reflection Diffraction

Polyethylene 2.5 High Low Low

https://www.clrn.org/what-materials-block-wifi-signals/

I installed thick greenhouse polyethylene sheeting over double paned windows and glass doors with double sided tape. Greenhouse polyethylene is much thicker than shrink wrap plastic that is marketed to shield windows. Polyethylene sheeting insulates windows. It also shields radiofrequency.

https://www.amazon.com/gp/product/B0CM8QP5B5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

I leave a window cracked open in every room for negative ions to flow inside and to prevent mold and mildew. I don't place double sided tape on the bottom of the window I crack open.

Seeking advice on purchasing signal blockers to protect my home from local drones

Hi there, I recently saw an ad for a hand held DOS looking device which was supposed to be able to neutralize radio signals within 50' or so. I would like to find who was selling that device or something similar to have at home which will prevent drones from being flown into my yard while I am outside. I know all these drones have cameras and I feel very intruded upon. i don't know where the drones are from. I only want something to use for my personal space at home. Unfortunately i cannot locate the device for sale, it may have been something to do with CES 2024, but i cant seem to backtrack and locate the article which mentions it. Too many emails! lol.

Recommendations of hearing aids without bluetooth?

Which other models besides Phonak Virto P NW with size 312 batteries? The technology in the chip depends on how much noise reduction features you need, which changes the pricing. Here is the link to the Phonak website:

Current and Magnetic Field Relationship

I was living in Hughes county when they started surveying using thumper machines. That is one of the hottest counties for new fracking wells.

There is a website where you can search for petroleum wells including fracking at Drilling maps dot com.

It used to be free, but now it is subscription based so I don't whether Seminole county is on their radar now or not.

When you put more load on power lines, they produce higher magnetic field strength.

Perplexity AI says:

"Yes, a heavier load on power lines does increase the magnetic field strength. This relationship between current and magnetic field strength is fundamental to understanding electromagnetic fields (EMFs) around power lines.

Current and Magnetic Field Relationship

The magnetic field produced by power lines is directly proportional to the amount of current flowing through the conductors.

As the electrical load on the power lines increases, more current flows through the lines, resulting in a stronger magnetic field.

Factors Affecting Magnetic Field Strength

Several factors influence the magnetic field strength around power lines:

  1. Current magnitude: Higher currents produce stronger magnetic fields.
  2. Distance from the source: The magnetic field strength decreases rapidly as you move away from the power lines.
  3. Line configuration: The arrangement of conductors can affect the overall magnetic field distribution.
  4. Time of day: Magnetic field levels vary depending on electricity usage patterns, with peaks typically occurring in the morning and evening.

Typical Magnetic Field Levels

The magnetic field strength near power lines can vary widely:

  • Under 400 kV double circuit overhead power lines, the magnetic flux density at 1 meter above ground is around 6 µTrms (microtesla root mean square).
  • Most homes and businesses receive 0.1 to 3 mG (milligauss) from power lines and other sources.

It's important to note that while very high voltage lines (345 kV) can carry high currents and produce relatively strong magnetic fields, the voltage itself does not determine the magnetic field strength48.

Practical Implications

Understanding the relationship between electrical load and magnetic field strength is crucial for:

  1. Power line design and management
  2. Assessing potential EMF exposure in residential areas
  3. Energy harvesting applications, such as powering wireless sensors near power lines

In conclusion, increased electrical load on power lines does result in stronger magnetic fields, but the strength diminishes quickly with distance from the source."

Any changes we can make to our Wi-Fi router to give off less EMF?

Besides, lowering the signal strength, I’m wondering if things like a single SSID versus a split band putting 5 and 2.4ghx on different bands has any difference in putting off less EMF?

Is this a safe distance from radio tower?

My SO and I are looking to buy a property that is approximately 368,89m away from a radio tower. We are worried about the exposure to EMF from the tower.

This is the only informations I could find about the tower itself.

BB60c Spectrum Analyzer

Hi,

I’m trying to use the BB60c spectrum analyzer by signal hound to locate radio frequencies reaching my home from another country.

This is the spectrum analyzer below:

https://signalhound.com/products/bb60c/

If one uses a directional antenna, such as this one below:

https://signaltronics.eu/product/rohde-and-schwarz-he200/

and potentially a GPS, is there a way this can be achieved? Basically, can I identify and trace where a radio frequency signal is coming from? From thousands of miles away?

If yes, how precise can the location be?

Thanks, timatuu

Airtube earphones & making calls safely

I was curious about Airtube earphones, I've seen a lot of conflicting information and curious to gain insight on the subject.

 It's intriguing how some Airtube earphones have magnets and for me, that's an instant fail. I realise the metal jack to plug in the earphones could also be counter productive... although where the Airtube begins is where the harmful EMF is reduced to a safer level. Either way, keen to gain insight on the subject

 e.g. What would be the safest way of making calls without using the speaker function? e.g. would bluetooth headsets still cause issues but less than Airtubes

 Thank you & much appreciated!

Effects of headphones with wire AND bluetooth? Tinnitus, sleep, mental health, etc

https://www.reddit.com/r/Electromagnetics/wiki/index/#wiki_bluetooth

As a strategy to facilitate falling asleep & avoid being overstimulated by society's noise - which can fry my tender brain quite quickly - I bought headphones with good noise cancelling. They can be used wireless (bluetooth), but the wire can also be attached optionally. (Sony WH-1000X M3) I have a multilayered curiosity of using these and effects on my health. I'm curious if I can use this device in an acceptably safe way, or if I better get rid of it.

  1. I often use these headphones. For the noise cancelling however, the bluetooth must be switched on. I do not let the BT connect to my phone, but it is searching the whole time while this is on. Does BT searching give the full effects of BT, or is it minimized / absent? What is your experience?

1+) Would this use mean the effects are more that of wired, or wireless BT headphones? Or both?

  1. I have tinnitus, and see wired headphones are related to that. It seems to have intensified recently. Does anyone draw connections between tinnitus and headphones from experience / research?

  2. I am a very sensitive sleeper, if I use no sleeping strategies, depending on the situation, it may be very hard for me to fall asleep. I have developed certain strategies. I often use wired earbuds connected to my (airplane mode) phone, playing background noise (pink+brown+white noise from youtube). That can drown out sounds that could keep me up. In case I need more, I use my Sony headphones, put noisecancelling (and so BT searching) on, AND the white noise. Sometimes I even add earplugs under that if I'm forced to be in loud environments in daily life, lol. What ill effects could this have? I only let the noise play for about 1 hour, but the earplugs / headphones are in all night. Does using white noise from wired earbuds/headphones from an airplane mode phone cause concern over quality of sleep, tinnitus, mental health?

Being careful and recently concerned over sleep health and tinnitus, I've stopped using this last strategy. But the tinnitus can be loud, delaying sleep, and hearing any noise can keep me up. I'm intent to land on the most healthy strategy for sleeping, and will greatly appreciate all help. I also use these frequently for loud environments in daily life, and so also want to decide if this is a good option or best avoided. I also frequently use them in the car to listen to podcasts.
