This is driving me nuts.  I'm contracting out at *confidential client name* right now and am working amongst a plethora of servers and other types of hardware.  There is an abundance of noise in this room, but the main server rack has a device in it that is whining at a constant pitch. 

The noise itself ain't so bad.  What's killing me is that the constant pitch of the device is near to the pitch of some sustained notes in the 2nd movement of Rachmaninoff's 2nd piano concerto (which I am listening to).  When I say “near”, I mean the two pitches are severely out of tune together and it makes my skin crawl each time it happens. 

But thankfully, the 3rd movement now begins.  I must go.
