I'm over 50yo and what is worse is one ear noticably deteriorating moreso than the other one. I have a 4khz "hole" down about 20db in my right ear so center stage for me is about 11.30am on the dial. Very annoying. There are a few online hearing test sites around, here is one with 16/44.1 wavs. I can't hear 12kHz-0dB.wav :-( http://www.phys.unsw.edu.au/music/dB/loudness.html --markc ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
