The research paper title is a mouthful for sure, but it’s an interesting idea… basically a grid of mini Helmholtz resonators. Would sure look pretty on the wall, just wonder about its real-world effectiveness at low & high frequencies…

Anyone in the Southeast US have a brain for higher math, the patience of a saint, and access to a CNC router to make me some prototypes? Laugh

Hi Y, Using a tactic instead of a strategy to deal with small room acoustic issues is never a good idea. You need to develop a strategy for your room surfaces and usage and then apply the strategy to the appropriate tactics. Questions to consider: What is the frequency response of the tactic you are considering? How will it benefit the usage of my room? What will this tactic contribute to the overall sound quality of my room usage?
