Reflexion des Schalls

This technical engraving demonstrates the behavior of sound waves as they bounce off a flat surface. A sound source at point 'A' directs a beam toward a wall labeled 'C', illustrating the mathematical relationship between the angle of incidence and the angle of reflection. Cylindrical tubes are used to visualize the path of the sound, with lettered labels indicating specific points of geometry and measurement.

Athanasius Kircher was a pivotal figure who bridged Renaissance natural magic with early modern experimental science. This diagram, likely from his works on acoustics such as 'Phonurgia Nova', reflects his belief that the laws of sound and music were microcosmic reflections of a hidden, universal divine harmony.
