Only parts of the financial district are that way. In my experience the rest of the neighborhoods in Boston proper are annoyingly loud compared to other cities I've lived in (except NY, of course). I had an office on Newbury street that was an absolute nightmare to work in from about 6pm every night due to shoppers and restaurant patrons, and an office in DTX where I always wished the windows were way thicker due to the constant noise from crowds, buskers, etc. A few blocks away from that office, in Chinatown, I basically lived in an office where it was just constant noise from all the chinatown gate crowd even at 1 in the morning. And most of the last 20 years I've spent living in Mission Hill, Back Bay, Fort Point, South End, South Boston. All of them were lot louder than, say, Midtown Atlanta. South Boston in particular has both constant airport noise and a weird obsession with rooftop parties and fireworks, much to the detriment of my young kids' sleep.
