There's a phenomenon called "coil whine" which is expressed by several types and models of electrical apparati, including chargers, laptops, GPUs, SBCs (single board computers, which are small selfcontained computers), etc.
In particular, it's caused by electrical inductors and coils of a certain metal or alloy vibrating at a certain frequency alongside/when paired up to a board. The inductors and coils' physical (the metal or alloy) material frequencies match up with something else and this causes them to quickly expand and contract many thousands of times per second, which manifests as audible sound.
The noise produced by coil whine happens as long as the electrical machine is on, and is almost always unpleasant.
My own theory is that since it is unregulated flickering noise that is representing frequencies along a randomly chosen spectrum, which are seldom if ever tuned to a main note of 432 or 444 Hz, instead of a calculated static frequency, then it could harm spiritual progress.
AnthroTeacher, could you please ask a knowledgeable being on the true effects and dangers of coil whine?

I'm not sure, but I'm getting the 60Hz US (and 50Hz in places) AC frequency is more damaging.
Could a Ground Loop Isolator help with the coil whine?

"Could a Ground Loop Isolator help with the coil whine?" Like this one www.amazon.com/Mpow-Ground-Isolator-Stereo-System/dp/B019393MV2 ? I'm not sure, coil whine seems to come from actual oscillating coils, which may look like chips, or something like that. On AC power: because it's a low frequency, and in the case of 50 Hz it's not tuned to any good or interestingly positively useful number. All electrical lights, some more than others, particularly fluorescent ones, flicker on 60 or 50 Hz. This may be very harmful on the spiritual sense, although it's not in the physical as "the flicker mimics a flame".

This is a Raspberry Pi 4, a SBC, which is like a selfcontained computer. It can have 1 (not sold anymore except to industrial), 2, 4, or 8 GB of RAM. Its storage is a SD Card. It has been a common issue that these things begin emitting coil whine, either instantly or after some weeks/months of ownership. People have traced the coil whine to the left side, on the cluster of black, brown, grey, greenish chips near the power socket. If you can't feel anything from this static board image, I'm sorry, and I will try to get a live video instead. Attachments:

No, don't really feel anything from it. I think that if you believe it is harmful, then it is for you. If you don't believe it is harmful, then it's not.
