360° Sound Wave Propagation Simulation — Magic Speaker
How does sound propagate in a large partitioned space? This real-time physics simulation models the 360° propagation of acoustic waves from the Magic Speaker in a 2,000 m² building. Thanks to sound diffraction, a natural phenomenon where waves bend around obstacles, sound reaches every adjacent room through openings without needing multiple speakers. Compare this with conventional directional speakers, whose narrow beams leave uncovered areas between units.
Sound diffraction: the Magic Speaker advantage
Diffraction is the ability of a wave to bend around obstacles or spread after passing through an opening. The Magic Speaker naturally leverages this property to fill adjacent rooms without any dead zones.
Directional speakers: the limits of focus
Conventional speakers project sound in a narrow cone. This directivity creates dead zones between beams, requiring multiple sources to attempt full coverage of the entire volume.
Simulation methodology
This model uses the FDTD (Finite-Difference Time-Domain) method. The two-dimensional wave equation is solved in real time on a grid of over 200,000 points.
