Presumably much less- the datacenter was apparently not that disruptive until they tore down the trees between it and the homes. The manufacturing facility may not have been 24/7 either

It likely didn't have the power requirements either. I'm just guessing here, but that sounds a lot like turbine whine. (I've heard them elsewhere, not to mention been around plenty of aircraft) My guess is that they brought one on site like they've done to other facilities to provide on-site power where the local grid isn't sufficient.

The pledge by their CEO to shut down crypto-mining equiptment feels like a deflection to me, because I don't think that's the source of the noise. It's the turbine generator, and switching to AI I don't think will change the power requirements any. We'll see I suppose.
