Freeware like the 'ol "Noise for OS X"?

Noise was a great little app that created white/pink noise that would play through your headphones in a busy environment. Very calming.

Doesn't seem to be up anymore. Any other free solutions?

I'm not sure that is the best way to reduce the disturbance, listening white noise for long periods of time causes serious health issues. IMO you need either some earplugs or noise-canceling earphones.

BTW there must be a built-in noise generator in GB or L8&9.
