Ninja

I just picked this game up recently, and am enjoying it a lot. Only thing is that I have to disable all audio because the guests' consistent chattering really gets on my nerves when playing. Might be because I have a general anxiety disorder. I'd really like to be able to play with all of the other sounds aside from the guests, but I haven't been able to find a way. Does anyone know if there is a way to disable the guest chattering?
