How long have you had your bunnies? Buns will get used to noises they hear a lot, but you’re right in that certain noises can still be stressful, especially when they are unfamiliar.
Usually having the buns in a busy part of the house is actually better, because they get more interaction and attention. That said, if it is a lot of yelling and they seem stressed, then you could try them in your room.
It might be good just to try them in your room and see how it goes. Sometimes adding a white-noise machine or some calm music playing can help them not be so startled by other sudden noises. I wonder if maybe you could let them roam in your room plus a little hallway during play time if you think they need a bit more room to run?
