Generally speaking NYC is loud because of things people do. If we can reduce the amount of noisy shit happening in the city, then yes, it'll be quieter and a better place to live.
People in large cities are allowed to demand a decent quality-of-life.
NYC != Midtown Manhattan
Generally when people bitch about NYC in some kind of stereotypical way, they're complaining about Midtown. The majority of New Yorkers neither live in, work in, nor spend much time in Midtown Manhattan.
Yes, the article refers to something that affects a relatively small number of New Yorkers.
It sounds like you live in NYC. Do the helicopters tend to bother you?
Yes, helicopters fairly regularly fly over where I live. They can be very loud.
Is tourist helicopters really the biggest source of noise problems for you in the city? Why not instead focus on reducing the number of honking cars that drive by you?
When I worked in London, my office was very close to the flightpath for LHR. Aircraft were at 580m overhead (according to FlightRadar24.com) about every 90 seconds all day. If the noise stopped (wind in the "wrong" direction) it felt like a huge stress just disappearing. Pretty much the same effect as an unexpected sunny day in winter :-)
