This is a VERY general measure.
Quantifying the lower range is problematic - it's hard to judge exactly
what frequency is felt instead of being perceived in the ear.
The upper end varies depending on everything from ear structure to how
many SpeedMetal shows you've endured. Some people can't hear above
12kHz (victims of severe hearing loss), others can hear up to 25kHz
(part dog, maybe?).

It's pretty easy to prove, actually. Most people can hear a 12kHz tone,
right? So, all you have to do is listen to a Sine Wave at 12kHz, then a
Triangle Wave of the same frequency. Hear a difference? Most people
can. Why is this? If humans could't feel frequencies above 20kHz, then
you couldn't hear the harmonics of the Triangle Wave, which are above
20kHz. Filter out the harmonics above 20kHz & you have a Sine Wave.
Many acoustic instruments, and SOME analogue synthesizers, produce sound
way past 20kHz. Brass instruments especially, tend to have significant
energy up to 50kHz. So, listening to a CD can be a bit lacking. Don't
worry, the analogue tape that most old music is recorded on is lacking in
high frequencies too.
Pioneer has just released a 96kHz DAT deck (frequency response to
48kHz). Look for Sony & Phillips to come out w/ some sort of "Enhanced"
CD in the next few years so they can sell idiots yet another copy of "Led
Zep IV".
