For urban sounds, I'd put my club, Carolina Golf Club (Charlotte) high on list. (All of this "noise" has been nicknamed the "Carolina Symphony," and once you get used to it, it sounds mighty fine.) --
Heavily used train tracks border the north side of the course -- not quiet commuter trains, but noisy freight trains. On top of the track noise, the trains are required to sound their horns, which they seem to do with great glee, at a grade crossing at the road bordering the east side of the course.
Not only is there a road bordering the east side of the course, there's also a road bordering part of the west side of the course. Beyond the usual car traffic (and big boom speakers in many cars), the neighborhood seems to have more than its share of public safety vehicles blaring their sirens responding to 911 calls. (Gunshots in the vicinity of the course are quite rare, however.)
The Charlotte-Douglas International Airport is just west of the course, but, thankfully, flight patterns are north-south so the planes, while routinely visible, are not heard (for those who don't know, this airport is the 6th busiest in the world, just after Beijing, in terms of the number of take-offs and landings -- it's an American Airlines hub, among other reasons). However, the police department's helicopters routinely fly low directly over the course between their base at the airport and their downtown headquarters, and you do hear them quite well.
Then, just across the street east of the course is a large junk yard whose machines make mega-noise when crushing cars and such. On the other hand, in the past few years I haven't noticed the loud parties that used to take place at the veterans' hall just down the street from the junk yard. The junk yard just across the street west of the course is now closed, but it never was as noisy as the one one on the other side. I should also add that the residential neighbors on the south and west side of course are very quiet (and I hope that our sometimes-events with outdoor music does not disturb them).
