I wonder if there are similar complaints near large data centers. Because that’s all a crypto mine is.
My guess is a large data center has better sound insulation.
Do you remember the huge data centers of the 1970s and 1980s?
They were gigantic buildings with massive A/C systems.
My memory is that they were very noisy inside but quiet outside.
The data centers in northern Virginia look and sound like office buildings (on the outside).
