That depends. Here has something called "spatial audio," which means people get louder or quieter depending on how far away you are from them (just like in a real room). If everyone is close together, you all hear the same thing...but if a few of you break off and move away from the main group, you'll be able to have a separate conversation from the others.
If you're a Viewer in a Station, you can hear whoever you can see. If someone sounds quiet, try moving your view in the room to see more of them OR zoom out.
