As someone who is sensitive to noise, rural areas bother me far more than urban ones. Traffic is low-frequency and only rarely annoying, but the few times I have lived in rural areas or gone camping, I have been woken up repeatedly by the horrific screeching of birds. Louder, shriller, less predictable than any city noise.

There are birds in cities too, and they are annoying, but they are thankfully drowned out by the cars.
