My grandfather was a car mechanic after he come out the navy and always had a stethoscope in his tool-box. He'd listen around the engine before diagnosing crankshaft or valve maladies like some kind of auto-doctor. Come to think of it, machine listening techniques could be deployed in a modern mech-engineering to predict physical failures in advance given how easy it is to embed a piezo crystal and and TPU core.

It has been done for decades.

Yes, I remember reading something about its use on bridges and giant steel structues to listen for bad welds when the wind blows.

I guess for auto stuff there's so many embedded sensors in a modern engine there's little need these days.

There’s still plenty of bearings and pumps that wear or make noise without setting a code or having the computer tell you what to do.

They don’t use TPU cores, but most of not all modern commercial helicopters and aircraft have vibration monitoring and reporting. I would assume the same is the case in many other industrial systems as well.
