Haha,,,I replied to Brad too about the noise being in my damn bedroom!!! No I don't have battery operated devices lol,,but my problem sounds like it's coming from every direction walls n ceiling. It sounds exactly like high pitched ringing in the ears except constant and louder,,,it's over my TV, really strange. I'm not crazy but I was thinking it could be government or aliens lol, only because I went searching for answers and noticed many others all a sudden having same problem
