AFAIK "professional/medical" tests like 8 bands and may have put a decibel meter to their equipment this month. or not.
some professional audio engineers have some special recordings they listen to on everything and use a faith based or at least difficult to quantify internal process to come up with the "right" sound. I'm more in that end of the spectrum.
Ah okay, I'm surprised there isn't something more precise and scientific out there. Interesting to know that the theoretical gold standard I would really want might not even exist.
Edit: I stand corrected, as the poster below mention (I can't reply), I'd want an audiogram from a professional. Thanks!
