This subject is known as "Active Noise Control", and I know that
there's a FAQ *somewhere*, possibly on alt.sci.physics.acoustics
or comp.dsp, and probably on news.answers. Otherwise, try searching
I suspect it won't help in your case - you'd maybe have to measure the
sound at your ears, and replay it there too. But I could be wrong.
Otherwise, move house, dispose of your neighbour, or put a dozen carpets
on the wall.
