> have a policy to keep the space as quiet as possible

I work in a similar dystopian open office panopticon, and I'm shocked, every day, that this isn't something that everybody is intrinsically aware of. But where I work, there are some Important People who have offices with doors - who leave the doors wide open, put their phones on speaker, and shout into conference calls all day, every day. The inconsiderateness of some people is really mind boggling.
