When you're in a Room the people closest to you are outlined in a colored bubble. You'll be able to hear the people in your group at full volume, while the volume of those outside of your group will be lowered
Part of the magic is how sound dynamically changes the same way it does within a physical space. That being said, when you want to talk to someone, you should be able to hear them clearly. That's why we created groups. Within Rooms, groups are created naturally and organically as you move closer to other individuals. Groups are indicated by a ring showing around each person's bubble and the view will adjust automatically so that everyone can see each other at once.
Groups (clusters of people that have optimized audio levels amongst them) can be configured to have a maximum of 2-20 users. By giving you the agency to decide the size of your groups, you have better control over how you want your team to interact.
