You can make a room without noise. It's really expensive but cheaper than going to space.
they showed one on tv, maybe to emulate space.. with basically spiked foam walls.. the spikes go out a fair bit from the wall (maybe 1 foot / or 3rd of a metre) and pretty much deaden the room..
reminded me of one of them rooms that where the walls would compress indiana jones / star wars style
