[Disclaimer: the following are just some
vague musings here from a
random nobody on the internet etc. etc. blah blah blah.
And I haven't even glanced at a calculus equation in around 30 years and I present nothing technical here anyway, so anyone with actual expertise in such matters,
please save your corrections and criticisms for Rob Watts and
his claims, since
he seeks profit and glory while at most
I might get a few extra 'likes' on a forum. haha!

So, even
if Chord had an anechoic chamber that was vastly superior to the recent Microsoft one (-20.6 dB, I think), and
pretending human hearing was capable of such feats as hearing and differentiating -130 dB or -150 dB,
what transducer is capable of producing these sounds at such incredibly low levels of distortion?
Random motion of air molecules is something around -23 dB?
I think I read somewhere (is that vague enough? lol) that sets an absolute limit on anechoic chambers on Earth, so Microsoft's chamber is especially remarkable for getting so close to that level.
Can he diagnose an infection by hearing the difference as more white blood cells are in his bloodstream before his temperature begins to climb? He must surely be able to hear the difference between blood flow with his normal cell ratios as compared to when he has the slightest of infections. (I assume since leukocytes are more than twice the size of erythrocytes, it shouldn't be a problem for him to hear differences. Perhaps he can even distinguish even finer differences, such as the sounds from changes in platelet ratios, or even virions?) That should be trivial considering his claims about his hearing acuity.
Sadly, the rising noise floor from the increasing sound of his own bones and joints creaking as he continues to age will reduce his abilities, even if his hearing itself is miraculously unaffected by the ravages of time.
