Default OT <--(sorry) Hearing at high frequencies

No where else to ask this, plus you're all a smart bunch.

Today I got my new laptop at work and the help desk brought it in and said
they had to send it back because it was making a high-pitched sound that was
annoying. I couldn't hear it. I asked a couple of others to come listen to
my laptop and tell me what they heard, and without knowing I couldn't hear
it and without knowing the help desk was going to send it back, everyone
said high-pitched sound, maybe hard drive or maybe video. More intrigued at
why I couldn't hear this, I asked others, and some even said it was giving
them a headache to hear it. WTF? Could there be frequencies some people
can't hear that others can, similar to how some animals hear frequencies
that no human can hear? I asked people of different ages and there was only
one other person about my age who didn't hear anything at all, but some
close to my age heard it loud and clear. I have never had a reason to think
my hearing is impaired.
