Researchers embed 3D prints with acoustic meta-data that manipulates the production of sound

Sound cancelling headphones have been around for years in one form or another. Whether it’s digitally controlled buffering methods or the good ol’ fashioned ear-plug variety, the buffering of external noise to suit our needs is something people have been experimenting with for years. A group of Columbia Engineering researchers has taken this to the next level by leveraging the advantages present in manufacturing with 3D printing to control sound waves using a computational approach with the ability to convert arbitrary shapes into very controllable acoustic filters. To do this, acoustic voxels (or small and hollow cube-shaped chambers through […]
