Cheap alternative: cover the walls with thin chicken wire.

  I got a better one. Use an ethernet cable.

    what? is that like some sort of wifi over wires? neat.

      No, it's just easier to obtain than chicken wire but has similar metal content for signal scrambling, and plastic insulation to avoid scratch damage to skin.

  Unfortunately something like this is not nearly as effective as you may imagine. I spent more money than I'd like to admit a few years ago trying to shield my hi-fi stereo from all sorts of interference. I lived on Avenida Paulista with about a half dozen to a dozen massive radio and tv antennas within about a mile. No matter what trick I tried the noise was still getting through in every way imaginable.

    These kind of filters are attenuators, not blocks. If you're that close to very powerful transmitters, then even reasonable attenuation is going to allow some signal through.

      Yup. I learned that the hard way. The best I was able to achieve was putting power cord chokes along the entire length of the interconnects (RCA <-> RCA). The ideal solution would be balance power amp and balanced pre-amp with XLRs carrying the audio signal. Unfortunately this would have required completely new amps.
