The photogrammetric and reconstructive modeling of cultural heritage sites is mostly focused on visually perceivable aspects, but if their intended purpose is the performance of cultural acts with a sonic emphasis, it is important to consider the preservation of their acoustical behaviour to make them audible in an authentic way. This applies in particular to sacral and concert environments as popular objects for photogrammetric models, which contain geometrical and textural information that can be used to locate and classify acoustically relevant surface properties. With the advancing conversion or destruction of historical acoustical spaces, it becomes even more important to preserve their unique sonic characters, while three-dimensional auralizations become widely applicable. The proposed study presents the current state of a new methodological approach to acoustical modeling using photogrammetric data and introduces a parameterizable pipeline that will be accessible as an open-source software with a graphical user interface.
