Chachacha, try this: When you hear the hum try turning of the circuit breakers to that area of the house. If the hum disappears, I tend to agree with previous comments about a possible power supply problem, LEDs, CFLs, or even your computer power supply. Hi frequency sounds tend to bounce around a lot, so you may have to try multiple rooms. If all else fails, hit the main breaker, if you still hear the sound, I am out of ideas. Once the sound disappears, turn on circuit breaker one at a time, when it comes back, start turning off individual items.
Hope this helps.
