Move. This one sounds drastic, but it may be worth it. Sometimes barrier walls and thick curtains can only do so much (and we’re not about to line our walls with egg carton foam). While moving outside the city (or perhaps suburbs) will reduce your sound levels greatly, it is not possible for everyone. However, be aware that sound levels can vary quite a bit even within a city. You may not have to move very far to experience a significant drop in noise. Choosing a home away from aircraft paths, trains, highways, or industrial districts is your best bet. Several cities (such as San Francisco) have even published noise maps showing which streets and areas are the loudest.
