It's a dumb idea and I'm mad
No, actually it's a good idea. Usually someone else was doing the communicating-he would have a voice-tube or sound-powered phones, so he would relay any messages to the captain, so you would likely only hear the nearby voices. Still, as I said, it might be cool to hear voices from other compartments come through all tinny and 'speakerish'.
Oh, and welcome aboard.
