We had that happen last year. Kept hearing a high pitch noise. Hubby couldn't hear it...but then he can't hear a whole lot!

Anyway...thought it was coming from the refrigerator. Called our repair guy, he came out, didn't hear anything...but I still could. Unplugged the fridge...NOPE...still there. He couldn't find anything wrong and left.

While I was getting something out a lower cabinet I realized it sounded louder. Turned out it was the AA battery in our waffle maker. It was dying and causing the "finished" tone in the waffle maker to emit a low frequency. Removed the battery...and the sound stopped. So glad I wasn't going crazy!

So check your small appliances or timers that use a battery. It could be that. Good luck!
