@kimberly_fuhrman-jones I know this was a fun idea, but I do have a serious idea posted regarding inserting files. Please take a look and like to help gain more support. Let others know as well.
Until this idea gets enough support, consider the Enscape realtime rendering add-in which allows for sound sources to be placed in your model. So you could have creaking doors and flushing lavatories while virtually moving around your building.
