Now that phones work on the subway (here in Toronto), I sometimes find myself having to take calls while in transit. And one of the things it has made me realize is that the subway is a very noisy place. It's not a suitable place for calls.
But interestingly enough, I only really realized this once I started taking calls and once I wanted it to be quiet. Before that, it was just the sounds of the subway and it was perfectly fine from an auditory perspective. And that's maybe the thing about noise in the city: it's relative, and it depends on your expectations.
Here's an excerpt from a recent article in the Atlantic by Xochitl Gonzalez that refers to urban silence as "the sound of gentrification":

The city [of New York] started going after boom boxes, car stereos, and nightclubs. These were certainly noisy, but were they nuisances? Not to the people who enjoyed them.
And here's another quote that directly speaks to its relativeness:
