This was quite disappointing. It would be interesting to see what are actually the loudest cities (via measuring sound at various spots), but this doesn't do that. It doesn't even tell you if European or American cities are louder.

I think it does. The loudest American city, Boston, has just 12% of the population exposed to noise levels >65 dB, while Europe's top ten is in the range from 29% to 59%.

You can of course disagree that this is the right metric to measure.
