If you go the "molded to my ear" route, do not forget that your ears will tend to change over time and these must be replaced periodically or they'll become uncomfortable and less effective. (I forget what the recommendation is but I think every 1-2 years at the outside.) On Wed, Sep 23, 2015 at 10:29:25AM -0400, David Hubbard wrote:
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. :-)

What are people using for ear protection for datacenters these days? I'm down to my last couple of corded 3M 1110:

These work reasonably well in practice, with a rated nominal noise reduction rate of 29dB. Some people find them uncomfortable, but they work well for me.
There are other ear plugs with rated NRR of up to 32-33dB. Anyone have any opinions on what brands work well for them?
