I don't have specific examples but I have read of standard manufacturer tools to do audio analysis of diesel engines to diagnose which part(s) are failing. AFAIK this has been a standard type of diagnostic for decades, although perhaps not as widespread or cheap to do as it is presently.

Similarly, with some practice, identifying engine types by ear (and possibly models) isn’t out of the question. Airplanes, too, not just cars.
