What is the underlying value we're trying to say with this?  "There is no guarantee on quiet time" isn't a value, it's a policy decision.  This isn't saying "we value noise".  Nor should we limit it to "hardware" work being loud.  Correct me if I'm wrong, but I think what this is really trying to say is, "You need to be considerate of other people's working needs.  If that means they need to be loud, you need to respect that."  Being considerate of other people's working needs -- that's absolutely a value, and an extremely important one, and it's as applicable to the need for noise as it is to the need for quiet.  The problem I have with the existing statement is that it does a very poor job of communicating that sentiment.
