A lot of the things they name aren't inherently city noises, either, though. I don't live near any concert venues or airports, so I don't hear noise from either of those sources. You could live in the middle of nowhere, but if you live above the local bar, it shouldn't come as a surprise that it's loud on Friday and Saturday nights. Dogs and birds aren't exactly uniquely urban phenomena, and the sound of peoples' shoes on the sidewalk being a major source of noise just strikes me as absurd.
