Rats! I was thinking of getting an ANC-4, but from the sound of things it would be only 
marginally helpful in my case.

I guess the only real solution is to move to some place at least 100 miles from the nearest 
power line and run the entire house off batteries.

The outback of Australia might be a good place...or possibly the middle of the Pacific Ocean 
somewhere.

Poop! :-(
