Columbia Researchers Put Acoustic Filters in 3D Prints for Tagging

Researchers from Columbia Engineering are currently working with MIT and Disney Research to further their exploration of 3D printing and sounds. Now, they’ve found a way to embed voxelized structures inside 3D printed objects to act as acoustic filters, opening up the potential for controlling sound waves in numerous ways. This could lead to acoustic tagging so that objects have their QR code or even a copyright built inside them. Ultrasonic manipulation as well as cloaking are being explored too. All of the researchers’ findings will be outlined at SIGGRAPH 2016 in Anaheim, CA on July 27th, as they present their paper, ‘Acoustic Voxels: Computational Optimization of Modular Acoustic Filters'.
