Been living downtown for a month and it's still a delight. The noise at night took some getting used to but now it's like rainfall. The muffled thump of music from the bar across the street, late-night conversation from a sidewalk cafe below my window, it's strangely soothing in the dark.
That's one of the things I miss from living in the city, and I enjoy getting to hear again whenever I do a NYC trip or the like.
Urban background white noise is a whole soundscape.
