I just did this test in a completely unsuitable environment (bad PC, just using PC piezo speaker in the case with the CPU, under an enclosed desk, with heavy office a/c and a conference call going on in the background), just to see if I could hear the 16kHz tone (because i was pretty sure I couldn't). I got the 12kHz tone fine, which kind of surprised me, and at low volume, I didn't get anything out of the the 16kHz tone. But at higher volumes, it made me shiver all over - really creepy. Just to test it, I asked someone else to press back and forth between super low-volume 12kHz and 16kHz and just from the shiver I could tell it was there, but could not discern a great deal else (though it was really annoying, like I remember the flyback circuit being from my old CRT TV). Anything like that happen to anyone else?
Curious about the state of your hearing?
Audiophiles tend to make outlandish (and unsubstantiated) assumptions about their hearing acuity. I used to get an audiometer test every year, but it became expensive and depressing.
The University of New South Wales in Sydney, Australia now has a fantastic online interactive audiometry test with a great user interface. Grab your headphones, try it and weep! Then report back, and be honest!! Tell us your age, high frequency limit, and any unusual loss at a specific frequency.
