If you can hear above 18 KHz, then you have exceptional hearing. In the past I could hear at least to 18.5 KHz. That was where the test equipment (headphone) capped out. That was 15 years ago. My vision is very poor, but I hear (or at least, heard) like a bat. I still hear a lot better (by a *wide* margin) than all the people I know, both younger and older than me, even though I'm not 18 anymore.
I've just ran a frequency sweep on my laptop, and in the low 15 KHz range, it just stops sounding. It could be that it's me not being able to hear the frequency anymore, but the laptop capping out at around 15 KHz is also a distinct possibility. I'll have to attach either my Senn headphones or Shure earbuds. They both can go higher.
Thus even *if* you can hear above 18 KHz, it's not even certain that your equipment will be able to reproduce it.
