It most certainly could be your speakers instead of your hearing... the crappy speakers I first tried it on I could only hear 14Khz and lower. Even though I am 48, I've always had very good hearing so I figured it was the speakers. (although I acknowledged that my hearing might not be as good as it used to be)

However, I just tried the test with a different set of speakers and can clearly hear the 20khz and even the 22khz but I do have to crank it up pretty good to get it over the background noise. (There's a dehumidifer and freezer running in the same room)

The wife however, who's also 48, can't hear worth crap. (I thought she was joking at first) That explains why she sometimes asks if the song I play for her is the original artist or someone else, I don't think she hears as good as she remembers the song!
