Agreed, as most of the buildings have great insulation or double-pane windows. Though during the summer, just don't have an open window facing a major inclined street like Universitätstrasse with constant tram and vehicle noise, and high revs up the hills (this is a major problem in SF, except many buildings are thinner and less updated). In Switzerland, one issue is the older churches ringing their bells every 15 minutes 24/7. The Swiss Noise Council is trying to limit the bell-tolling to day-time hours. http://www.swissinfo.ch/eng/for-whom-toll-the-bells-_church-bells-charm-and-annoy-their-listeners/40807288 http://www.swissinfo.ch/eng/for-whom-toll-the-bells-_church-...
