High over Fulton Street in Downtown Brooklyn, foot-long microphones are being installed, which will pick up and analyze the neighborhood’s potent mix of sounds, allowing the city to move towards the automatic identification of noise polluters. Roberto Gautier, whose apartment at 140 Cadman Plaza West overlooks the Brooklyn Bridge, suffered through years of noisy bridge repairs. The major work wrapped up in 2016, but Gautier said the nightly drilling of jackhammers and annoying backup beeps of construction vehicles affected the health of many of the building’s residents — and even their pets. Gautier, a member of the Department of Transportation’s Working Group, says residents of the building experienced “almost continuous sleep deprivation” for roughly three years. “Noise pollution in the ‘city that never sleeps’ involves having one’s sleep interrupted, which affects one’s ability to function healthily and happily,” he told the Brooklyn Eagle on Saturday.
