Has anyone come across a device that could cancel out the noise from
servers, ie. the fan noise? I have a server rack near my office and would like to see if i can decrease the noise level. It would seem to me that the steady drone of the fans could be cancelled out to a large extent.
thats really hard to do because the noise source is diffused, and reaches your ears via multiple paths, plus your ears aren't at a fixed location.
Its easier to move the servers to somewhere you won't hear them, like a
server closet that you can soundproof and add forced ventilation to. or wear earplugs.

Interesting. In my case i wanted to decrease the amount of noise escaping through an open door (which can not be closed.) After reading the various comments i think I might search for acoustic blankets for musicians.
