I believe there is much research to the contrary, though it is not my area,=
 so unfortunately references are not forthcoming.

I do remember the days before CD, reading the white papers as the tech depa=

at Sony wanted a 100 KHz sampling rate, or thereabouts. Now, of course, we =
have 96 KHz as a hi-end alternative, but this was far from being deliverabl=
e at the time.

Still, Sony held out for a higher rate since psychoacoustic research had sh=
own that frequencies well above the so-called 20 KHz maximum affected one's=
 impression of a sound. (I additionally recall they used solo piano as a te=
st case.)

Whereas Philips wanted 32KHz or lower, because their concern was to make so=
mething cheap and get it out the door. The compromise was 44.1 KHz, as we k=
now.

I could once hear a clear but subtle difference between the CD standard and=
 higher sampling rates. But only in the studio with excellent source materi=
al. Thankfully/regrettably I am older now, and doubt I could do the same.

I also used to be able to hear bats. The sound was most uncomfortable to me=
. In fact, I would not characterise it as a "sound" as such. Maybe others w=
ith more experience know what I mean.
