The chatbox 2.0 becomes more transparent the farther they are and then vanishes, however, It does not sync up to how some people's hearing/deafness works and doesn't account for people with hypersensitivity, disability, conditions, or needs.
Separating the audio and chatbox controls into their own individual controls would greatly help people with different sensitivities and needs.
Some need the audio earmuff circle a certain size and the chatbox circle wider, especially if they're hypersensitive to sounds, or get easily overloaded by how many people they find vocally talking in an area. Maybe they're having a Sensory Overload Panic where they need the earmuff super small and need the audio outside of the circle completely muted, but still need to see chatboxes at a distance... I myself fall into this circle.
For others, they need the chatbox circle smaller than the audio circle, they may be going to rave events where they want to communicate with their buddies and strangers in a specific area, but do not want their view obstructed by other people using chatboxes in the crowd outside of the area and still want to hear everything that's happening at the event.
