This technology is a system and resulting acoustic diffusion structure that receives architectural structural data, plots points on a corresponding 2D plane, divides the plane into polygonal Voronoi cells, and designs a 3D acoustic diffusion structure using each cell as a base and a polygon with the same number of vertices as the top surface.
Interior materials for spaces requiring acoustic diffusion, such as concert halls and opera houses, must evenly disperse indirect sound to enhance clarity and diffusion. However, conventional acoustic diffusers have uniform surface shapes and areas, varying only in height. This leads to sound waves failing to scatter effectively and instead concentrating in specific directions.
This technology features a processor that sets a virtual vertex at a fixed height perpendicular to the base's center of gravity, draws virtual edges connecting to each base vertex, and then randomly selects heights within a set range for each vertex to determine the top surface vertices along those edges. The heights vary per vertex, the top surface is smaller than the base, and the structure can be designed as either concave or convex. Applicable to wall finishes in concert halls, opera houses, auditoriums, recording studios, and home theaters, it automatically creates reflective surfaces with varying sizes and slopes per cell, evenly scattering sound waves while generating unique design patterns every time.
This invention was developed with support from the Ministry of Education for the development of acoustic diffusers for performance venues using liquid acrylic mixtures.
