This is a long shot but anyone know if there's an audio recording of the sound the display produced? Curious
Edit: Found it: https://advanced.onlinelibrary.wiley.com/doi/10.1002/advs.20...
Go to supporting information on that page and open up the mp4 files
Good find - the first video is a frequency sweep, video 2 has some music.
Edit - I'm not sure that's the same thing? The release talks about pixel based sound, the linked paper is about sticking an array of piezoelectric speakers to the back of a display.
edit 2- You're right, the press release is pretty poor at explaining this though. It is not the pixels emitting the sound. It's an array of something like 25 speakers arranged like pixels.

This is the article that should be the main link- though still an incredibly misleading named technology.
But the current one is just wrong.
This technology literally sounds like a terrible idea. Why do I want to hear one drummer's drum over the others?
