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?"
