Noise cancelling only really works on ambient noise, so unless your coworkers are queuing up "Music for Airports", it won't really help. It also can't create silence, and will still damage your hearing over time. The best solution is for the people that want noise to just use headphones!

"[Noise canelling will] damage your hearing over time" Do you have a good source on that? I'm thinking about getting some noise-cancelling headphones for office use.

  Not noise cancelling specifically, just wearing headphones in general for 40 hours a week.

  There's no good source on that, as it's wrong. There's absolutely no damage from noise cancelling, and in fact they're healthier than regular headphones (because you don't need to raise the volume to drawn out external noises).

      >Unlike cell phones, noise-cancelling headphones do not emit low level radiation and do not pose any of the potential hazards that could stem from frequent use of a cell phone held next to the ear. >Actually, noise-cancelling headphones can be beneficial, since both loud noises and constant low-level noise can lead to health problems. Acute loud noises can damage hearing, interfere with sleep, raise blood pressure and stress levels and cause headaches. As for low-level noise, a study published in the Journal of the Acoustical Society of America in March, 2001, found that Austrian children who live in neighborhoods with constant low-level noise (mostly from automobile and train traffic) had higher levels of the stress hormone cortisol than youngsters who lived in quieter neighborhoods. And a study published in the February, 2006, issue of the European Heart Journal found that heart attack risk was higher among people exposed to chronic noise. I actually recommend noise-canceling headphones to help avert the health problems noise exposure can present. http://www.drweil.com/drw/u/QAA400774/Are-Noise-Cancelling-Headphones-Safe.html http://www.drweil.com/drw/u/QAA400774/Are-Noise-Cancelling-H... And tons of others -- besides the basic lack of any mechanism by which noise cancelling cans could be harmful for the ears compared to regular ones. The burden on proof is on the "damage" side.

I met a lady in a coffee shop once who wore earplugs and headphones. She wore the earplugs so she could play the headphones really loud without damaging her hearing, while blocking out all the ambient coffee shop noise.

Headphones with good passive attenuation will block any kind of noise. They are essentially industrial ear defenders that also happen to be excellent headphones. Headphones with Bose-style active noise cancellation are an ineffective gimmick. Headphones of this type typically provide around 30dB of attenuation, enough to reduce loud music to a gentle murmur. I highly recommend them to anyone who works in an open-plan office. http://europe.beyerdynamic.com/shop/dt-770-m.html http://europe.beyerdynamic.com/shop/dt-770-m.html http://en-uk.sennheiser.com/hd-280-pro http://en-uk.sennheiser.com/hd-280-pro http://www.extremeheadphones.com/passive-noise-isolation-hearing-protection-headphones/studio-products/ex-29-headphones/ http://www.extremeheadphones.com/passive-noise-isolation-hea...

  Headphones with Bose-style active noise cancellation are an ineffective gimmick. Not if you fly a lot (or even a reasonable amount). I don't have Bose ones, but active cancelling works amazingly well for that constant hum on airplanes.

  >Headphones with Bose-style active noise cancellation are an ineffective gimmick. They are actually very effective, both for airplane style noise, but also for street noise, people talking in an office, and music playing. Haven't tried Bose themselves, but active noise cancellation on Parrot Zik's works well, and all reviews say Bose's is even better. Plus, if you also play your own music on top, you can't really hear anything -- to the point of it being dangerous if you're walking in the street, crossing roads, etc.

>Noise cancelling only really works on ambient noise, so unless your coworkers are queuing up "Music for Airports", it won't really help. You'd be surprised -- plus that is flatly wrong. I have a pair of noise cancelling cans (Parrot Zik 2) and they can totally eliminate street musicians coming aboard on your subway train and playing and singing next to you in full blast (we get that a lot in my country) -- along with all other train talk and noises. Same for office music and other things -- it's not just for ambient noise by any means. And the Zik are not even considered the best cans out there in their noise cancelling department.
