Low sound, comes and goes like a boomerang. It first starts out of nowhere but once I hear it it's almost like it's doing oval circles around me. The sound increases and decreases but doesn't go away until I finally fall asleep. So far ilI have only heard it at night. I'm a healthy 27 year old who doesn't take medications, I don't drink alcohol and my hearing is great. This humming noise is something really different from anything else I've heard. When I first heard it, I turned off all the plugs on the walls as I thought it was electrical, I then turned off the fan and walked in other rooms but it seemed the loudest in the bedroom.
