What could this strange vibration noise be?
Here is a sample you can listen online on Whyp.
Other recordings can be find on GitHub.
What I have confirmed are:
- It is not ambient
- It often has an area of effect with a radius less than 1 meter
- It is distinct from some other normal vibration sources
- The centres of occurrence can be ordinary things, sometimes right at my head
- There can have multiple occurrences at the same time
- Since the area of effect is small, the occurrences I noticed were around/at my head
- It is faint most of the times, tend to be louder at night with the quietness of night considered
- Sometimes a centre of occurrence seems to be able to move
- Other properties such as pitch(frequency), volume(strength) and size can also change or vary
It has been a few months since the first time I noticed it around my head when I was sleeping.
What could it be?
Here are some things I have found. Whether the noise is produced by one of these hypersonic, microwave or EMF devices or not, it is most likely produced by some kind of technology.
The most important information is in the first OHCHR pdf. I have experienced most, if not all, of the what it lays out. Some which are still on going.

I do experience vibrations in my head but it is not constantly, it comes and it goes. Mine seems more like a subtle vibration, it's hardly tangible on the outside and when there's less background noise, it gets a bit louder.
Mine isn't constant either. I have spent quite some time to confirm mine is external. Sometimes it is inaudible but still cause discomforts.
Tangible as in being able to feel the sound and where it is coming from.
That's a great start, hope you find and understand more about it.
