Sound Distribution Figure (IMAGE)
Caption
The figure shows simulated changes in sound pressure level distribution, or how sound travels and changes across a specific area, in different applications, visualizing how the team's metasurface can effectively focus audio into a tight bubble of isolated sound. The top layer highlights the distribution for a traditional transducer — or the physical component that helps convert electrical signals to sound energy in a speaker, the middle layer showcases a traditional PAL and the bottom layer demonstrates an PAL topped with the team's acoustic metasurface.
