Look at this Poll

How high can you hear (with music & lowpass)

The poll starter didn't put frequency above 20 khz in the poll
So why don't just use a 40 khz PCM instead of 44.1 khz as human
can't listen to frequency above 20 khz?

16 x 44100 x2 = 1141.2 kbit/s

16 x 40000 x 2 = 1280 kbit/s

It does help to save some space!

If you can or can not hear above 20Khz etc you can percieve it on at least a subconcious level. Sustained high frequency sound combined with psychotropic compunds etc has been show to have a definate impact on the human nervous system IIRC. Often invoking unprovoked anger or rage that would not otherwise manifest.

Aaaaah Nyquist theorem...............
