So I've got this neighbor who doesn't really realize (or rather, don't care) that we have quite thin walls between us and when he blasts his stereo on full I get a uninhabitable sound environment in my apartment (over 80dB of bass). I've complained to him and to the landlord but nothing really happens so I've thought maybe I could do something about it myself.
The idea is that when you put a cellphone in close vicinity to unbalanced audio equipment it creates a lot of distortion when you make a call to it. So I figured maybe I could amplify this, or replicate it some other way so it would distort equipment in a larger radius. Would it be possible to do this without creating a device that would be dangerous to use?
