Either my computer speakers haven't the ability to reproduce those
sounds, the files are corrupt, or I need to get back to the
audiologist.
Seriously, a while ago I went to have my hearing tested so that I
could show my classes what happens when you spend a lot of time listening to
high-decibel rock and roll music -- like on the edge of the stage at a
concert. I have a decided high-frequency deficit, and it shows up really
well on the audiogram. I was an idiot. (I may still be, but that's
another story...) It hasn't gotten down into the range of ordinary speech,
but it's clearly there above about 10 kHz.
In that lecture I also talk to them about iPods and other things
when used in a noisy environment: damage that only gets worse with
age. When you're in a noisy environment your inclination is to amp the
volume of the stereo, and they can easily get into the range that will produce
damage if listened to for an appreciable length of time. My advice: don't
wear a personal stereo when vacuuming or riding the subway. The damage is
cumulative.
