Active Noise-Canceling Headsets In Server Rooms?
An anonymous reader asks: "Recently I co-located our computer room to a temporary hosting facility. It's a big shop, with everything you could want, along with quite a high dB of background noise. I've no desire to wear those silly little yellow earplugs for several hours when I'm on site there, and standard headsets are such non-IT apparel. Given that technology is the cure to many of todays evils I was wondering if any people had experimented with active noise canceling headphones and has something to say about them. Does anyone use any active noise canceling headsets in a computer room or data facility, and if so how good are they?"

The customer reviews pretty much sum them up - I've even got one in there. They do a FANTASTIC job at filtering out our 500 servers, with or without playing music.
I've owned and sampled various active noise cancellation headphones. At best, I've found them to be good. At worst I've found them totally ineffective.
To attenuate high dB environments, I'd consider the "good" of headphones I've tried to be less than satisfactory, i.e., my subjective evaluation has been about a 10 dB or so drop in levels, good, but if you're looking to get rid of noise these won't do that. If the room is loud enough, I think they'd only lessen the noise to barely acceptable levels.
You mentioned you don't want to wear the silly yellow ear plugs... there are some available in other silly colors. ;-) On the other hand, you aren't likely to be anymore comfortable with headphones on the whole time, and you're going to look no less silly. I've found earplugs to be quite effective, and they're something you can get used to.
If you're looking to "use" headphones, i.e., listen to music, you might consider various ear-canal headphones. I own a pair of those, and aside from the amazing sound quality of the music, I get about a 30dB attenuation of ambient noise. Two birds with one stone. YMMV.
Good luck!
Check out the SAGE sysadmin toolbox page, and scooch down to "What's the scoop on hearing protectors and noise-cancelling headsets?". (The whole damn page is useful, too...)
Carousel is a lie!
These are the best portable headphones i've ever used. They're not active noise cancelling, because they're so damn good they dont need to be. Put them in and be amazed. I used them extensively in a large (and very loud) server room and was very VERY impressed with their noise cancelling abilities.

Oh shit! I forgot to click "Post Anonymously"...
I've got to second the in-ear canalphone recommendation. For one, they use less power (and don't require their own batteries) as most noise-cancelling phones do (better for portable player life). They have excellent broad-spectrum attenuation -- typically far superior to noise-cancelling. And if you invest in a decent pair (even the $80 Shure e2c's) they'll sound a heck of a lot better than most any noise-cancelling set. If you really step up to the plate, Shure's E5 series or Etymotic Research has some models that will simply blow you away -- Shure's even has a "push to hear" feature that allows you to hear outside noises clearly without removing the phones. And the sound quality on these higher-end models is right up there with the best -- period. The same can't be said for ANY noise-cancelling phones.
Of course you have to get used to having something stuck in your ear....
