Seems like a waste of tax payer money to me. Just put up with the fan/keyboard noise. Done. Maybe crank up the speaker volume for whoever has the mic.. There are people out there who struggle every day with shitty cars that break down all the time because they can't afford anything better. I just loaned my jump start battery to one. Wasting people's money on preventing fan and keyboard noise seems like a real let them eat cake moment. If they think that's a real problem, they are too well equipped to actually feel real problems.
Different people have different tolerance levels for such noise. I'd suggest you not presume that all people disturbed by such noise are 'over-sensitive whiners'.
An example. I can take a football (soccer ball) full in the face from 3 meters, without a complaint. It wasn't intentional. Shake it off.
I cannot concentrate with such noise in my periphery, particularly when the background is not "busy" with other activity. My nervous system wants, demands that I pay attention to it. Part of the... "heightened alertness" that serves me well, in other contexts. Perhaps also somewhat the result of a childhood in which such noises could proceed very traumatic events.
So... those of you with a "Why can't they just put up with it?" attitude: There are those of us who have tried -- often pushed too hard to view this as entirely our fault -- to do so. For years. Decades. It doesn't work for us.
Why should you then "put up with us"? Well, in my case, I tend to notice 3 or 4 times as much as many of my neighbors, and to relate it ("cross reference", whatever) to things they've long since forgotten, if they ever knew. In my case, at least, what you are "disturbing" is a very deep and full and "well-intentioned" attention. It takes all my concentration to perform this well.
This attention catches and fixes problems before they become "established policy", or "code", or whatever, depending upon context.
I don't care how you lead your life. Just don't presume that it gives you the right to infringe upon mine and my well-being. Don't assume that you understand my experience and motivations.
If one were to bring in a desktop computer with even noisier fans and keyboards into the parliament chamber, would that be OK? If a member just had a bunch of loose fans running at his desk, and banged away all day on a disconnected keyboard, would that be OK?
Why not just ban the thing causing the problem itself, and not worry about contingencies that are orthogonal to the problem (e.g. what kind of larger-scale devices the noise-making items are embedded in)?
