I've used hearing protection occasionally. You might not realize
that's what it is, though, because it's just the my usual closed-ear
headphones with the cord running into my pocket. What's not obvious is
that the cord isn't plugged into anything in my pocket. They advertise
over 30dB of isolation from external noise, and, while I haven't put
decibel meters on them, it would not surprise me if they deliver. I
once used them when the fire alarm went off in the building I was in
and, in the hallway I had to use to leave, it was well above my
threshold of pain. A pair of headphones and it was still loud, but
nowhere near painfully loud.
I've never seen people wearing hearing protection
at rock concerts
either.
Well, I've been to concerts and worn hearing protection, but, unless
you were within a couple of seats of me, you would not have been able
to tell, because what I was using was the in-the-ear kind that's pretty
much invisible unless you're up close.
The problem is that people tend to ignore insults to
their hearing
until it's too late.
_Some_ people. :)
