Talking in Hz doesn't make sense because sensory JND's vary as a
function of the frequency.  That's not a musical claim, it's just a
statement about the hair cells and basilar membrane in your cochlea. 
So although +/-1 Hz is way above your frequency discrimination
threshold at 50 Hz, it is way below your frequency discrimination
threshold at 5000 Hz.  Discussions of the range of human hearing
should be conducted in physiological (not physical) units.  So in my
opinion, I don't think there is any meaningful sense in which 7kHz -
20kHz is 1/3 of the range of human hearing.
