This topic was previously posted on the Hello South Loop page. We received a lot of feedback and found more residents affected by the noise pollution created by Digital Realty. I am hoping we can reach out to even more residents in the South Loop.
Across from the west side of the Transportation Building, there are chillers on the rooftop of 600-740 S Federal Street. They are owned and operated by Digital Realty. Recently, they have doubled the amount of chillers that operate 24/7 above the city's noise ordinance, 55 dBa per Ord. 8-32-090. The sound levels recorded reached 79 dBA inside the units. The equivalent of 70 dBa is a vacuum cleaner, and 80 dBa is a garbage disposal.
I am reaching out to understand if there are more neighbors in the area who are also affected by this. There is another Digital Realty location on 350 E Cermak Rd.
Here are some videos of the noise pollution during different times of the day.
Please comment below or email me (email@example.com) if you have any stories or advice battling noise pollution.
There is also a facebook page with more information on the issue:
