High frequency noise at night doesn't stop for many years. Moving to other home doesn't help to rid from it. Is there someone who suffer from the same? What can be helping?

Have there been any recent changes in electronics in your home? Has the utility company installed a smart meter ?

Sometimes tv's can put out a high pitch when they are turned off and revert to standby mode.

Unplug ALL your electronics at night and let us know what happens.

I would even shut off all Breakers. Water can make noise, maybe try shutting off water as well. If no luck, may not be at your house.
