Construction noise inside a nearby apartment building: way off the charts (though not as bad inside a unit); maybe state, FCR officials should check it out

Atlantic Yards Report


Maybe Arana Hankin, the state official in charge of Atlantic Yards, and Jane Marshall, a Forest City Ratner executive, should take a relatively brief evening walk from their Fort Greene homes to check out the deafening construction noise at the intersection of Fourth Avenue and Pacific Street.

Marshall recently likened the additional stretch of overnight noise to a dentist's appointment that would be over in a month.

But that's not quite right.

It's probably closer to a long-term dentist's visit without any novocaine. After all, one resident of 568 Pacific Street described it as "torture."

At that building on Monday night, inside a hallway, a visitor registered a 94.0 dB reading on a decibel meter, as shown in the photo at right.

That's way, way off the charts.

Measuring impacts

The upper acceptable limit at night, according to the city and state, is 65 dB, which itself is way above the recommended level of 45 dB, as noted below.

But there's no evidence anyone officially involved in Atlantic Yards has tried to monitor this, or to offer promised mitigations (see below). Hence my suggestion above.

As shown in the chart at left, from a New York State Department of Environmental Conservation (DEC) guidance on noise, sound becomes intrusive as it approaches 70dB.

It becomes annoying at 80 dB.

At 90 dB, it becomes very annoying, and can cause hearing damage after continuous exposure.
