Mmm I'm 26 going on 27 and I can still hear that annoying whine of CRT's even though I've PURPOSEFULLY BEEN DAMAGING MY HEARING by grinding and working on metal in college welding classes without hearing protection for 7 months. I think all I achieved was no longer being able to hear above 16 KHz<br>Funny thing is as a kid, it never bothered me, or at least, I never noticed it on most TV's and CRT monitors unless they where a shoddy built CRT that made a lot of noise at 60Hz but putting screens at 75, 80 or 85 hz made that noise go away for me as a child.
