Here's A Weird One For You!!

I wasn't sure where to post this, so please move it if you think there is a more appropriate forum for this question....

I am picking up the TV audio from the downstairs neighbor in my apartment building through my PC speakers!! My system is acting like some sort of an 'antenna' or something, I would think. Granted, it is very low, but it is noticeable, and since they seem to watch a lot of TV, it is irritating and actually I can hear their TV audio when I play music and that really is annoying.
I am wondering what may be going on here. Could it also have something to do with the wiring in the building? This is a two apt. dwelling.

And if you have an idea as to what is going on, some possible solutions to get rid of this. Thanks.

 

What may work!!! I got away with it awhile back, take a length of phone wire long enough to wind around the speaker leads, Start at the machine with that end grounded to the case, wind the wire all the way to the speaker one for each lead, doing so breaks the natural field of electricity around the wires. May or may not work depends on the signal strength coming from down stairs.
