After awhile, I stopped noticing the noise. Maybe because I was so dog tired from a day's work that I was ready to sleep.
When we were able to move to a quiet neighborhood, my wife (who had gotten used to the road noise as well) had trouble getting used to the sound of crickets chirping and frogs croaking. We still laugh about it.
I grewup listening to air hammers at night at the Dana Corporation in Toledo, Ohio, one block over from us. I had a lot of sleepless nights when I moved.
