It is surreal that this article showed up now. I am going back and forth currently with our electric utility company. They upgraded capacitor pack on the pole by my house. And these new ones are generating so much of this kind of low buzz sound, it is unbearable. I was researching into what generates this noise, and found this article very timely. Only solution is to move these, as nothing else can be done about this sound. Which is turning into quite a project.

It is quite rare for capacitor banks to hum. Much more likely that you're hearing the magnetics (transformers), which indeed have reason to be where they are. Good luck.

Thanks. Indeed those are transformers, upon further digging(for some reason, I think of transformers as big, these are not big but boy they emit this low-buzz sound). And indeed it has been very challenging to have them moved, because as you said they probably picked this location based on a reason.
