40 is common during the day on a residential neighborhood. 54 would be obnoxious, the equivalent of someone putting on a roof a few houses away (ask me how I know). 54 nonstop at night when you’re sleeping would be awful. I’m generally pro-datacenter but this isn’t right.
This "awful noise pollution" line everyone says about data centers is complete bullshit.
I bought a decibel meter from Amazon and went to a data center in Ashburn, VA. Right outside of it reads at 52-54db which is not loud!
