Kerfonic Wall: The Sound of Kerf: Kerf panels with various cut patterns and densities are compliant allowing for easy shape reconfigurations of the surface (macro-scale topology). Its microstructural complexity by default can be utilized to manipulate wave propagations in the panels. A kerf panel based on its cut pattern and density can have an interesting acoustic response characteristic. The 20’x8’ plywood wall was designed with multiple segments of double curvature kerf surfaces for sound-focusing purposes. The curvatures of the segments are controlled by cut patterns and densities and the stiffness of plywood. Each segment is tuned for specific acoustic diffusion and absorption characteristics. Installing the kerfonic wall significantly drops the reverberation time of an open-plan area, allowing visitors to have quiet private conversations. The kerfonic wall is displayed in the Autodesk gallery in San Francisco. Contributors: Artists: Negar Kalantar and Alireza Bohrani. Researchers: Zaryab Shahid and Anastasia Muliana
