I live on Second Avenue between 11th and 12th streets. Verizon has been testing their emergency generator on the roof of 204 Second Ave., between 12th and 13th streets for the past year or so. The noise from the generator is incredibly loud, like the sound of a jet engine at close range.
The DEP told me that by code, the emergency generator must be tested at least once a month. The tests last an hour or more each time. There is no predictability when the testing will take place. Verizon has turned the generator on very early Sunday mornings, and sometimes in the middle of the day. On Monday, the generator came on twice, once at 5:30 in the morning, which woke us and other neighbors up, and then again around noon. Wednesday night at 7 just as we sat down for dinner, the generator went on again for about an hour.
I have taken to calling the DEP each time the generator goes on and they have offered to come to my apartment to monitor the noise level. The DEP needs to take a reading when the generator is on and when it is off to get the ambient sound level in the apartment. If there is more than a 10db difference between the two then we have a case and Verizon could be ordered to do some sound attenuation to bring the generator noise below the threshold set by code.
The DEP has been very helpful, however so far we have been unsuccessful in getting them here with a meter while the generator is running. I have taken readings on an iPhone app and have found the sound of the generator to be over 10db from the ambient noise level in our apartment.
I am wondering if anyone else in the neighborhood has taken any action. Thanks for your help!
The noise is coming from the metal chimney shown here on the south side of the Verizon Building roof.
