Wisrah Villefort and Sarah Johanna Theurer’s research project ›GODCRYSTAL‹ deals with the effects of sound produced or appropriated by humans and the ecologies it constitutes. The objective is to consider the ontological aspect of that sound and specify its agency. Within JUNCTIONS21, they have studied theories of soundscape ecology, developing vocabulary and — following Donna Haraway's situated knowledge—critical tools to dissect notions and concepts such as anthrophony, biophony, ultra-, and infrasound. The title ›GODCRYSTAL‹ makes reference to a brand name of a popular ultrasonic bark control device.
