It's not air interference from the walls. Just test it.
-Get a power strip and put your PC and monitor on the floor in the biggest room in your home, in the middle of the room - the farthest possible from any wall and sockets
-Build a "tent" from aluminium foil -the foil should be on the floor with the PC and monitor sitting on the foil, and then simply cover both PC and monitor with foil, fully. Use duct tape to seal the foil on the floor, and then simply cover entire area, so both monitor and PC would be fully inside the foil tent, no air gaps - leave only the very small hole for your mouse and another small hole where you could see on the monitor, and a small gap for power cord - which should also be covered in foil.
Any air inteference from walls / outlets would be suppressed, if you are far away from walls and use aluminium foil it is not possible to interfere anymore. If the problem is still there, its the wall electricity problem, not air.
The problem is 95% overloaded / loose neutral wire, because in many apartments, the neutral wire is shared between all apartments, and someone has some heavy load on it and mess up entire building. At the night, many people stop using electricity = less noise on neutral. And what can we do about it? Literally nothing, they would need to re-wire neutral through entire building, or install extra neutrals, and this would cost 10,000€+.
