Actually, I have it on pretty good authority (an MD), and there is information out there to back this up, that the average (average) 40 year old male tops off at around 14khz. That's assuming no lifetime of regular rock concerts and airport tarmacs. By age fifty, that number is cut in half -- you're down to 7khz. And, from there, it's a continued nose dive.
When I play a test tone sweep through my speakers, the sound level, to me, diminishes rapidly as the freq goes higher and then it sputters into a hiss. Interestingly, while looking at the computer, the measurement is still going...and the extreme high frequencies are measured (I use Fuzzmeasure for the Mac and a DBX mic with Presonus Firebox audio device, both calibrated). Oh: I turn 41 in a couple of weeks. -- highdudgeon SB3, Lavry DA10, Sony DVP 555es, Bel Canto Pre2, Carver Sunfire, Rane DEQ60L, Harbeth Monitor 40s, ACI Force subs ------------------------------------------------------------------------ highdudgeon's Profile: http://forums.slimdevices.com/member.php?userid=2195 View this thread: http://forums.slimdevices.com/showthread.php?t=24693 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
