Wristwatch Jokes

What could this noise? Subtle, acute / ears ringing as from a single piece of the house.?

Four family members age Miscellaneous hear sound in one room. My son can not sleep in her room where noise is heard. We have checked all the electrical appliances and toys, windows (thought it might be crickets and is not), TV, lava lamp, smoke detector, etc. You can not hear the noise in his closet or hallway or any other room in the house. We even took his watch from the room. It is a constant, barely audible, high pitched sound, as if your ears are ringing and the sound is not real, but you have an eye / headaches, and if in his room for more than a few minutes. What else could it be??? What should we check? He sleeps in the guest room at the moment, because it is unbearable. Myself and our 30-husband to hear, and my son who is 10 and our daughter who is 6. This is not a joke or a riddle ….. Please then only offer thoughtful suggestions. Thank you!

I would like to first turn the main power in the cutting area listen for noise. If it disappears, it is something electrical. Possible the bell transformer, etc. .. Next turn the electricity back on a circuit at a time to see if the noise reappears. Then follow the circuit to isolate the malfunction. If this does not sound try to isolate the noise to see if it comes from the attic, walls or floor. It could be water flowing in a pipe or air flowing an air / ventilation pipe. Good luck …..
