The concept you outlined is technically very feasible but economically prohibitive. There are high value situations that incorporate these techniques as standard practice. For example, the diagnosis of rolling mill fault conditions with FFT vibration monitoring has been in practice for at least 50 years. Of course when a cold strip mill goes down, the damage can be measured in megabucks.

- KeplerBoy 3y agoNothing about this is economically prohibitive. This is predictive maintenance 101.
- dghlsakjg 3y agoFor consumer level cars, it is not hard to predict or catch something that is actively failing with simple visual inspections, and scheduled maintenance. You can spend millions designing a fancy acoustic system to measure things indirectly, which will need to be installed at a cost of hundreds per vehicle and the be maintained itself. Or you just have the mechanic give it glance during an oil change (which smart mechanics are already doing free of charge), and pay attention to the dozens of existing sensors that are already reporting the critical stuff. Acoustic sensors won’t catch everything so periodic inspection is still needed. Worth noting that all modern car engines already have acoustic sensing in the form of a knock sensor, so the car companies are well aware of sound/vibration sensing technologies. In other words I doubt that a fancier acoustic monitoring system would prevent enough maintenance/damage to justify its own cost.
