Finding that pesky ground loop hum - or not

[Schwingding]

Thought I would share this with you for its humor.
-------------------
I spent a whole lot of time last evening trying to narrow down a ground loop hum in my system.

Everything appeared to be connected together correctly - and all of the power cords go into the same conditioner/suppressor except for the amp separates, but they're all on the same GFI circuits, and since I wired them in, I know the ground is good.

So I started unplugging devices, one by one. Hmmm... no change. Completely disconnected the sub from the power cord and the lead. No change. Did not want to unplug the DVR, but did it anyway. No change! OK, pulled the plug on the whole darned system.

Still hums!

Wait a minute.....

Walk into the kitchen a room away - its the damned refrigerator! Unplug it, still hums!! AAAAHHHHH!!!!

Microwave? Unplug it. Still hums! I'm nearly beside myself with frustration at this point.

Then it dawns on me. I'm on an antibiotic for an ear infection. It is in my head, literally! I walk outside - and hear the hum! I hear it this morning in my office, too....

I had the same thing happen except it was a little different. Last Thursday I started taking Clindamycin (strong stuff) and Saturday I started hearing a faint ringing type oscillation. At first I thought it was the monitor on the PC, then the TV then the air conditioner. It was following me around upstairs, down stairs, kitchen etc. I didn't notice it outside and sometimes it was louder than others. My wife never heard a thing. After checking every electronic and electrical device in the house and listening to the walls (South Philly has some really bad wiring), I happened to be reading the side effects leaflet from the drug store. Why I still had it I don't know but there it was in black and white the sound was in my ear. I still have it off and on but now I'm not chasing it around. My wife was beginning to think I was getting schizophrenic but I kept telling her I wasn't hearing voices.
