I'm wondering if I remember an urban legend or other apocryphal story. From the headline, I immediately thought of an answer I swear I learned about in some machine learning class years ago. People were struggling with a food inspection device that tapped (cheese? fruit?) like this, trying to emulate what a human expert did. The punchline was that the human expert didn't really know how to articulate their decision either, and it wasn't listening to the drumming sounds at all, but merely dispersing some odors to do a better sniff test.
