City streets seem to work the same way. I realized while making a phone call back in the summer how noisy it is outside. The key, though, was not just to make any call - I've made plenty outside in the past without really worrying about it. The realization came when I made a phone call outdoors that I usually make indoors. The contrast was enough for me to realize how loud the street was.
I've tried to remember this lesson anytime I'm tempted to make a call outside. Things are much better from my apartment where it is much quieter...unless it's one of those weird moments where I've just noticed the refrigerator humming...
