wuzzzer Posted April 28, 2022 Share Posted April 28, 2022 That's pretty wild. I wonder what useable frequency range they would produce. The article mentions testing at 1kHz. I like the active noise cancellation possibility with the design. I can see that being a lot more useful than covering an entire room with the stuff for immersive audio.
