I visited Copenhagen a while ago and one of the most remarkable things was how _quiet_ it was. Or rather, what I could hear. People talking, birdsong, passing bicycles, and just.... life. It hurt to leave.

I still remember standing outside with my finger in my ear shouting in to my phone just barely able to hear people walking around in cities in California.

Notjustbikes does a great video on this https://www.youtube.com/watch?v=CTV-wwszGw8 - "Cities Aren't Loud, Cars are Loud"
