People perceive audio events in very different ways. There is still a great deal of uncertainty about the physics, biology, signifiers, and unconscious processes on the basis of which auditory experiences are constructed. The book applies the methods of artistic research to convey a sense of how mental space, social practice, and the direct experience of sound relate to each other and how connections are generated between these levels—a topology of resonances, reflections, and vibrations in perpetual motion.
