Well went thru the links and not one sound clip I heard of this noise - which I find equally just as odd, lots reports of the noise and clips of people getting there slot of TV fame, but not one link to the actual noise - least what I gleaned thru. So who knows, just equally as odd no recordings I could find of this noise, though there must be some out there somewhere I'd imagine if it is that much of an issue.

Given the ubiquity of sophisticated cell phones and other recording equipment, it's best to regard the lack of a recording as strong evidence that it does not exist. Just as if multiple people claimed the Loch Ness Monster had surfaced in San Francisco Bay but somehow there were no photographs of it.

It is incredibly hard to record silent noises with standard equipment.

Yes, but article clearly states the neighbours can't stop talking about it. They're so busy talking about it that they haven't made time to record it.

Be patient. As soon as they all stop talking about it we can hear the noise.

What a BS linkbaity vaporous article. For all anyone knows Apple could be repairing an AC unit. Oh, and while I'm in a ranty mood. Aren't all labs "mysterious" from the outside?

Since EVs are very quiet, it could be a rolls machine, which is basically a treadmill for a car. They are used for running tests on vehicles and are outrageously loud. They can be used during prototyping. In a car factory it's at the very end of the assembly line and sometimes used for debugging vehicles that have come off the line with issues.

In the automotive industry, we call them dynamometers. Though you'll never hear anyone say that, we just call them dynos.

Not necessarily, it could be a rolling road, which is more similar to what the OP described.

Why should apple care about that? The cost of salary utterly dwarfs energy cost so much that even thinking about the slightly cheaper rates at night is a joke. Apple is not a process manufacturer where energy is a large part of the budget.

Unless they're melting their own aluminum. =) Note the article doesn't really mention electric-type humming. One neighbor described the sounds he hears at night as "sheets of metal slamming, clanking, almost a grinding sound." This idea they're running large amounts of electricity to charge EVs seems far-fetched. And if a charger is making that much noise to wake the neighbors then, well, they have larger technology…

I realise you're joking, but one doesn't turn an aluminium electrolysis cell on and off at a whim (as in off in the day, on in the night). Shutdown and restart is bloody expensive, dangerous, and hard work to boot.

So that's what they are called. When I worked for Chrysler everyone in the plant called it the rolls machine.

Are you? http://www.pge.com/en/mybusiness/rates/tvp/toupricing.page?W... Instead of a single flat rate for energy use, time-of-use rate plans are higher when electric demand is higher. This means when you use energy is just as important as how much you use. Winter has two rate periods: off-peak and partial-peak. Summer has three: off-peak, partial-peak and peak. During peak periods, defined as weekdays from noon to 6…

Doesn't California also have some the most expensive electricity in the US?

We're talking about a company with $200 billion in cash lying around. They could build a few large nuclear plants without making a significant dent in that pile of money.
