This might already be implemented, but if it's not.
It would be awesome to have performances spill into other rooms. You have a huge full band performing, in a bar, club, out in the open, but one street down you hear nothing of it.
I know with shouting it travels multiple rooms, so would be cool to have one room you hear it clearly, get the full benefit.
Adjacent rooms you hear it but with text cut out similar to half heard conversations.
rooms further just some ambident "You here the sound of a performance near by"
It could allow performers to be found more organically.
These effects could be lessened by doors, walls, so on.
Also it could upon up RP of people eves dropping on performances and not paying, give something to do for bouncers and the like.
