Columbia Engineering Researchers Use Acoustic Voxels to Embed Sound with Data

Monday, July 18, 2016 - 12:01 in Physics & Chemistry

Columbia Engineering, Disney Research, and MIT researchers have developed a method to control sound waves, using a computational approach to inversely design acoustic filters that fit within an arbitrary 3D shape while achieving target sound filtering properties. They designed acoustic voxels, small, hollow, cube-shaped chambers through which sound enters and exits, as a modular system. Like LEGOs, the voxels can be connected to form a complex structure and can modify the structure's acoustic filtering property.
