In this detailed visual documentation of Johanna Zinke's research, the reader is presented with entirely new perspectives on language and its effects on humans: Each sound creates a specific, describable flow shape during exhalation for a brief moment, which can be made visible with certain tools. The various sounds result in a diverse world of forms. This volume includes recordings of all sounds and sound combinations of the High German language, documentation on the dynamics and formation of air sound forms, and various visualization methods, as well as drawings to assist in observing the spatial structure of air sound forms. The visual section is complemented by fundamental discussions on the significance of this new research approach and its physical foundations.
