Without a doubt, the city is much more exposed to noise. You've got constant traffic from cars, buses, and trains, and there always seems to be some kind of construction going on. People live in close quarters, so you hear everything from your neighbors to nightlife on the streets. On top of that, shops, restaurants, and entertainment venues all contribute to the overall noise level. I live in a city myself, and honestly, it can be noisy even in the middle of the night.
