[BC] interesting audio

[Mark W. Croom]

Oh, this story. I heard this on a national network yesterday, and it caught 
my interest then.

I definitely can't hear 15khz like I used to, no doubt about it.

I loaded your mp3 in Adobe Audition, normalized it to -.1, and cranked up 
the headphones. Sure enough, it was there. But BARELY, to my ears.

I also ran a frequency analysis on it in Audition, which is where I learned 
that it really was 15khz.

I'm sure I'm not the only guy who has known some people in radio who cannot 
hear high enough frequencies to even know when their digital watch alarm is 
beeping. Personally, I can't imagine being that deaf (though I suppose it'll 
happen in enough years). I try to be very cautious about how much I crank up 
those headphones on a routine basis.
