I think that 44.1 was chosen to be sufficiently good that only dogs and
bats would notice the limitations.

It is generally accepted that human hearing is 20-20,000 Hz
(https://en.wikipedia.org/wiki/Hearing_range and many other sources) and
diminishes with age.

For those who go on about how good FM radio is they should note it doesn't
go anywhere near 20 kHz. ;-)


It goes to 16 kHz which is quite close.

They chose to cut it there so they coudl fit in eth 19 kHz pilot tone and then use the bandwidth up to 38 kHz for th stereo difference signal.
