Low frequency noise pollution can be very disturbing to anyone suffering from such. It can become a form of low level torture
1. Any motor hat is not vibration isolated from the buildings structure can transmit low frequency noise into that structure and local structures sharing the same foundations or party walks.
2. Ball race Bearings are used in machinery and these can be a source of noise and vibration. Ball race Bearings can be noisy in operation and when they fail they can be particularly noisy. He noise is usual, in the higher frequency ranges however. Frequency mixing remains a possibility however.
A faulty Ball bearing from a semi-industrial fan hung on a supporting beam was part of my hypothesis during first year. (As written below), when the neighbor renewed flats in his building, I wondered how much I heard the drills and bore machines. As I was recording I have particular Spectrum of that period.
Any bed matress is going to act as a huge attenuator to any building vibration.
When the problem started, it was highly noticeable, head on the pillow.
It's hard to notice as it is a very discrete shake. As soon as I sit down on my computer desk, get quiet to code, I feel it under the thighs when sitting. Foot on the ground I notice a feeling of impatience, as with the "ants in the legs". I rest my legs on some leather+foam pouffe to avoid as much as possible that impatience in the feet.
Neurologist stated nothing particular when I visited her. I later made some Xray related to hears and the physician, a long time specialist, stated everything was fine. Good ear boy !
I was particularly feeling well in the waiting room for the Xray chamber, weighted down by this big farraday's cage walls. *moan*
If I lay down on my matress, the side laying connected to the matress is feeling it. And the most annoying the head's side laying on the pillow raises the same feeling. I would say the frequency your box shake on the video could be what I feel. So I tried to change matress. I put silent block under my matress. I put layers of antivibration gummies under those silent blocks. It was lowering a bit the stress. Doubling the pillow wasn't better (I sleep with german pillows, as they are best pillows IMHO, BIG pillows.)
Added to the difficulty to sleep, I was waking up with cervical contractions, feelings of fatigue pain in the vertebral column.. Insane. My eyelids were turning black, with bags under my eyes.
I dunno why but wondered how people are doing in high seismic activities' area, like in Central America or Japan, and remembered a friend told me about his year in Guatemala, and how people of that region put the brat in hammocks to make them sleep.
So I bought a king size hammock. Effect was quite immediate. Where I wasn't able to sleep before like 7 o clock in the morning, totally exhausted from trying to fell asleep, and waking up at 8.30AM for the job.. *cheers*.
I was still feeling some nights of troubles, thinking about it as "higher intensity" of what I get. But at least I was able to get to bed at midnight and do a complete night. What a deep progress. I think it took me like 14 months to regain the lost nights. And at least I can mostly sleep, be productive again.
MrBakerNeighbor started to wipe his whole building floors and build 4 flats to rent in it.
A point to notice was they dug a big hole just after their entry door, which is the closest to my Deskroom and Sleeping room, wall to wall.
Asking a contractor there, he told me they were going to pass all cables there, a fill it with concrete. I was sleeping quite well at that time and feeling less stress. Even if the noise for building flats was high, I was going better.
They stayed like 3 months with this hole in the entry and plywood boards above, making bread and "Le Patisserie" just nearby, without the slightest sanitary measures of insulation. Crazy.
After one year of different daily noises, they finally ended up the construction process and added this winter a second 400A line to his building, to connect new flats. Which, ended for me as feeling higher stress. More hard nights like in the beginning.
As some people pointed a cause effect to possibility: It's not some nocebo effect because I hate this guy and he is a complete stupid asshole. If there wasn't any trouble, I could perfectly live well just ignoring its proximity. As I already told Those troubles started long after he established his business there.
I maybe forgot to mention the FIRST time it started, it was a beautiful and perfect weather outside. Birds were singing, I just woke up from a normal night, perfectly rested. Window was open. It was like 20°C outside. 6'O clock, not the faintest car's noise coming by the window. I had just the time to think about what I was going to experience with an old Amiga I was customizing during my week-end that I heard a loud scraping sound of cast iron, metal against what I interpret as tile or stone.
Then the shit started, very high. I thought it was a refrigerated truck delivering a restaurant down the street. After 10min, I decided to go the street's front window. Nothing, not even a single bird whistling in the street. The "noise" never ended until the next TUESDAY afternoon, 15:40. I did a lot of shit in the week end, tried things to test my own house.
Exhausted by the stress, I also tried in summer 2019 to sleep in like every parts of my house, even in parts of my warehouse of my business and in the attics. Shit was the same. The feeling can dominates all the grounds of my house sometimes.
I never tested the basement to be complete, even if it's some descent concrete wall basement.
I did tries to rent a tiny house in the countryside also. It was fine.
If I go to a friend to sleep, it's just fine. But as we all have our own life, you can't always count of imposing your presence to friends.
As It's a convenient way to travel as well, I'm about to buy a boat and sleep in it when the trouble is too high.
Even hammered, I'm still interested to find the solution.
To get back on Grid Another weird thing in the neighborhood, is that sometimes at night, opening the window, no one in the streets, I can hear sometimes a regular buzzing sound. And in the perpendicular street the same.
If I go to the 2nd street next, nothing.
Concerning my house, it's 12x8m 2 higher floors and a business on ground floor. Sometimes I feel the stress while working at the ground floor, but less frequently.
On 1st floor I can feel the stress at table in the kitchen, but less frequently the same.
I can feel a rythmed noise in the living room often at 19:00-20:00 in the evening. I have 4 windows there under the distribution cable that runs the length of my cornice.
And nerdy, I'm mostly living on second floor. 1m50 from my office seat, there is this power distribution cable that runs all along the street.
Concerning the garden, in the back of the house, separated from the street by the house. I can also feel the shit. There is a boiler at the bottom of the property, which belongs to the town hall, and is also supplied with electricity.
This is why that small experiment with Copper rod and Multimeter reading Voltage on AC values remains still a point I'd like to perfectly understand.
Last but not least, I've read our Grid distributor is removing RLC filters from their 20kV transformers because of SmardGrid communication. *I strongly need a bunk/debunk on that claim*. Could it be possible that strong interferences arise from that ?
And that article raised my interest:

This is becoming schizo some will say again. This is why I'm asking questions into a Cartesian forum.
What I feel from my experience, but it's just my own empirism, I try to prove, is that there is Vibro-acoustic troubles AND Electrical troubles.
Thanks anyway for all the interest and tips you already provided. As someone tipped, I think about leaving by the end of 2022. What interest me the most on writing all my wrong experience, are materials and techs I could use to bust the problem. Not here for whinings or receive sorry guy "bon courage". I don't feel the need to talk to a psychologist's cell. That's for loonies.
I have courage.
