Usually don't have a fan running but we run the A/C and have a fridge. when it's at night I know its not the fridge because we are at the other
end of the house and the bedroom door is always shut. I would think if it is the fridge ( when I hear it during the day) that when I walk closer I
would hear it better but it just fades away as i walk to where i think it might be.
