I had a power strip that was buzzing a low sound for a bit, I removed it and threw it away. I've also had light bulbs [[usally florescent) giving off an odd sound. Check all the appliances to see. It took me a while to find out about the power strip sound and it could have been a fire hazard....

I also hear it in my basement because I have gone down there to check. My house is a ranch, no second story to report on.
