Crypto mines consist of literally hundreds of PC servers. They need two things, lots of electricity to power them and lots of fan power to keep them cool.
And fans, especially LOTS of fans, generate a lot of noise!
China outlawed cryptomining because of the energy consumption. North Carolina, and many Southern states, have inexpensive power and loose regulations. And an increasing number of cryptomining operators. Residents complain of an almost constant 50+ decibel whine/hum from the mines that can go over 70 dB at times. And have taken to their local governments to issue noise abatement rules and fines and it's members of both political parties that are objecting.
