Why does listening to Mozart symphonies change a child's willingness to open up and bond? And why do the sounds of Mozart help an infant calm down and become more aware of their body? How do hearing and listening reach the human heart? Dirk Beckedorf and Franz Müller systematically and understandably present the psychosomatic foundations of human hearing, as well as the history, application areas, and practice of systemic auditory therapy. They address both professionals and laypeople alike. The strength of the book lies in its ability to create bridges. The authors succeed in embedding the topic of human hearing into the discussions of modern attachment and brain research. Through this interdisciplinary approach, the examination of the ear and its associated hearing functions gains unprecedented relevance. In this new edition, the text has been revised.
