In 1802, Ernst Florens Friedrich Chladni published his book “Acoustics” containing visualizations of vibration modes in 2D. We generalize the well-known concept to 3D. Via computer simulations, we solve a corresponding physical system and thereby obtain an isosurface in a cubical model. This isosurface visualizes the elimination of sound waves and their reflections, showing points in threespace where different frequencies vanish. Using a 3D printer, these vanishing points can be physically realized. Application are given in instrument design or architecture of music halls. With transparent filament, constructors or architects can print problematic regions directly into their prototypes for awareness.
