Curious about the state of your hearing?

How depressing. I couldn't hear the 16k hz tone. My teenagers could. They loved it and wish they could talk in that frequency so adults like me can't hear them. Worse was that I had trouble hearing the lower frequencies. How come i can hear a 40hz tone on a test CD but not the 45hz tone on that website test? Is it just a matter of decibel levels? Fascinating and depressing.

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?

I tried the test with some AGK headphones and I could hear 30Hz to 8khz. Nothing above that.
I listened to my old Altec Santana speakers hooked up to two SAC La Forza Mono power amps fed by a Lynx 22 audio card in my home office and there I could also hear the 30 HZ very well ( I was surprised hear that the Altecs go so low!) and even the 12khz signal. I an 58. Not bad I think !
The only thing not so nice is that I suffer tinitus, so I often have that high pitch sound acompanying me.
