I had a next-door-neighbor who complained about my getting into her computer 
speakers. I fixed the problem by GIVING her a set of speakers in which I had 
added disk-ceramic bypass capacitors directly across every speaker lead into 
and out of the speakers.

She still has my speakers.

Her own speakers were still receiving interference when they were completely 
disconnected from both the computer and their power supply with all wires and 
the speakers lying on the floor..
