Yeah, I've just bought an AM radio for the purpose. And yes, on the first floor at the electric meter box it began to receive this noise. I will contact the owners of those appartments soon.

I recorded a video about the problem, added the Youtube link to original post. Did you mean something like that noise?

If it is a loud RFI, can the coils in AC/DC adapter pick that up and make it audible? btw, the noise in the adapters in load dependent. For example the mobile charger does this buzz too, but when I attach the mobile to charge it, it does it louder, the same is true for the computer's power supply too.

Yes the house is pretty old and I believe the wiring is quite old too... And yes the source is the AC/DC transformer. Even my speakers make this noise quite loudly when the signal cable is not plugged in. I don't experience overheating yet. Maybe it's due to undervoltage?

Assume they don't have the same problem. Wouldn't the power company able to detect these kind of problems somehow?
