If you can't listen it to at all in the bedroom it might be a series of things, from a clock, a tv, etc, you might want to ask your neighbor if they are having any problems or if you know them well enough Jim, ask if they have anything electrical in the bedroom above you. I wonder if they are using a ham radio or a sewing machine, etc. even a hair dryer can give yours short bursts of interuption. Come to think of it, I bet they got a computer above you in their bedroom.
