At least one heavy metal deejay and musician is aware of how loud he can be. Benjamin Sachwald might be bringing the noise at night, but at his day job he's rewriting the noise code! Metro reports that at his firm, AKRF, he's "updated the sound standards for the 21st century, adding requirements for Mister Softee trucks. The company also does readings for fed-up tenants living above bars and developers planning projects by elevated subways."
And about those subways... beneath the N/W tracks at 39th Avenue in Queens, the noise measured in at a pretty high 82 decibels. While the MTA is under no orders to follow the city codes, they do "plan to issue recommendations by January for reducing subway clamor." We'd be curious to know what how high the decibels get in DUMBO.
