Acoustic Metamaterial

thingiverse

This acoustic meta-material is a result of my design, fueled by a white paper published by Boston University at phys.org/news/2019-03-acoustic-metamaterial-cancels.html. While details about size are sparse, I've attempted to replicate the concept accurately enough. To achieve optimal results, print with 100% infill as this will significantly improve the material's performance. To determine which frequency range is blocked, use a frequency sweep app. Print the meta-material flat side down without supports and feel free to scale it along the x/y axis. However, be cautious when adjusting the z-axis as it may compromise the channels within the material. I've also included a relevant YouTube video published by Boston University at youtube.com/watch?v=Fd1D42dVxS0. Although noise cancellation worked for me, I make no promises that it will yield similar results for you.
