Didn’t know the people behind the mp3 format were into tooling for metalworking. Guess it makes sense, it involves a practical application for use of sound, and they are a research institution.

I wonder if the metal can hear the difference if it’s not the full 192 kHz.

That's not the same group. "Fraunhofer" is not a single group but the umbrella organization for 76 different institutes: https://en.wikipedia.org/wiki/Fraunhofer_Society

I'm not sure we can call it "the people behind the mp3 format". Fraunhofer is a very big instituion.

May be "PeopleS behind the mp3 format"? :))))

Really, I hear in early 90s, how Telefunken developed PAL TV standard (and also RGB, YUV and some other things, now you could read about on Wikipedia).

- They working like Gallop - asked people from street, to answer simple questions like "is this color Red or Yellow?", and with large number of samples they got statistical approximation, about curves of sensitivity of human eye, and then just use these approximation as direct wavelengths for Red/Green/Blue respectively.

Fraunhofer, as I know, used similar approach, but for sound, and got model of sensitivity of human ear.

So, what I want to say, for these researches don't need many scientists, but need wide enough sample and good reliable execution of math.

BTW, much later I read about research conducted in US air forces, targeting some ideal human pilot size to made most convenient plane control (and sure cheapest).

But they got so disappointing results, that have decide to make pivot - instead of make one standard size, they designed usual for us now adjustable chairs, tilting steering wheel, and pedals with adjustable suspension.
