Or might have sounded like, Darlings. It’s a project by a musicologist named Mylène Pardoen and is the first of its kind. This historical audio reconstitution was crafted by a group of historians, sociologists and 3D specialists. The sounds take the listener between the Pont au Change and Pont Notre Dame bridges. There they can hear the toil of the trades of the time — such as shopkeepers, craftsmen, boatmen and washerwomen, all on the banks of the Seine. The magic of this project is that it takes into account the echoes beneath a bridge or under a passageway.
