Shannon-Hartley Channel Capacity Theorem and textbook Psychoacoustics, Acoustics for real world room noise floors suggest we're no too far off with Redbook CD Audio
as well as the 3 decades of people outraged by Digital Audio not coming up with more than a handful of somewhat Scientifically Controlled listening studies "proving" 16/44 inadequate - and those few not replicated, haven't made it into the Psychoacoustic textbooks yet
Shannon-Hartley Channel Capacity Theorem is the Engineering Definition that best allows comparison of analog vs digital "channels" like recording/playback chains https://en.wikipedia.org/wiki/Shannon%E2%80%93Hartley_theorem
Stuart's whitepaper is pretty good for showing human limits and digital audio formats, go to the graphs at the end, scan back for the associated text: https://www.meridian-audio.com/meridian-uploads/ara/coding2.pdf
and Psychoacoustic testing by now has long experience, has evolved some standards: http://www.delta.dk/imported/senselab/AES125_Tutorial_T4_Perceptual_Audio_Evaluation_Tutorial.pdf
