high pitch sound/acoustic pressure-Acoustics Forum-Acoustic Fields Forum

Hi, we’re hoping someone can figure out our puzzle. We have a high pitch sound in our basement that is pretty much ruining our lives…my daughter can hear the sound, i have heard it sometimes,but when i can’t hear it i experience it as pressure in my ears…and its actually painful in addition to the tinnitus we’ve developed. We have insulated the furnace room, the hot water pipes, the baseboards, replaced valve heads and valves, drained and refilled the baseboards, tried turning off all electricity to house, searched for toys, controllers etc. We can’t pinpoint it….any ideas…? Thank you so much.
