I can hear Barry's "Interesting Audio", also (stereo, 15Khz tone in both 
channels) ... despite having a rather high-pitched tinnitus. I can also hear the 
15.7Khz of NTSC television flyback. Used to be, I could barely stand being in 
the TV section of most Electronics stores... but now that plasma & LCD screens 
are pushing the old CRT's out of existance, that is no longer the case.

There was a store I remmber in my 20's that had something like that. It had 
to be about 17Khz, at 90+db! Talk about *loud*! Finally, I had to stop going in 
there, it was just too much.

I thought that was what the Barry Manilo music was for? <g> Seriously, 
though, that signal will still bother most 20-somethings, unless they've already 
trashed their ears with their iPods.
