Ear protection

I wear one of two things:

1) The 3M Peltor 105 ear muffs which offer 30db reduction.
I keep them in my car because I also use them for the gun
range, they fit snug but not annoying.  They're only $18
on amazon: http://tinyurl.com/peltor105
There's also a behind the head bar if you don't like the over
the top kind.

2) A lot more expensive, but with a side benefit; I have
a custom set of ear plugs that I use for go kart racing so
I can have radio communication.  You can get them online
or at most race tracks on a race day.  Someone, or DIY at
home, will use a big syringe to squirt the mold liquid in
your ear, it sits for 60 seconds, then they pull it out and
send it off to have the ear plugs made.  They're very good
at eliminating noise but have the side benefit of a
headphone plug so you can still use your phone, ipod, etc.
while you're in the data center. :-)
