I'm 48 and top out at about 16khz plus have a very noticeable dip around 6khz probably due to an accident as a kid
Man.. this is some pretty good statistics..
I used the linked test with a DAC and amp and got some strange results:
AD700
18kHZ, 19kHZ, 20khz, 21khz OK
failed at 22khz
K702
Could not hear 19 or 20kHz, but 21 and 22 could be heard?!
HD-650
Couldn't hear 18, 19khz or 22khz, but 21 I could (LOL, what the....?)
DJ100
All the way up to 21kHz. Hardest one to hear was 19khz
BTW I'm 31 if that makes a difference.
I can easily here up to 17khz, above that turns from hearing it to more like sensing that there is a very high sound coming. This goes up to 19-20khz. Above that and I hear absolutely nothing, not even sense anything. I am 27 years old.
I could hear 19 khz at max volume, but 20khz was juuuuuust out of reach. I could definitely tell that there was a noise playing though, but mainly because there was a slight click when it started and stopped.
