Does White Noise Help In A Noisy Environment?

HenryWirz asks: "My cube is situated next to the office 'Relationship Consultant' which is quite distracting. For coding I crank up my tunes, but I find it hard to read documentation with music. I think the solution to my problem is white noise. So my question is: Where can I find good white noise CD's? How about those white noise generators?" Do you find that white noise helps you concentrate in a distracting environment, or are there other methods that might work better?
