There is a video, at least in the link I clicked, in the article that you can hear it and it is a huge difference

Yeah, i watched the video and it is some dude talking the entire time. Not one second of the sound was in that video. Then there is a video about boats, with engines running on top, and then another that has a dude.. just talking. Not one second of the prop itself making noise compared to traditional.

The video i saw had sound for both. The guy talks over it the first few times, but eventually you do hear the props.

Jokes on you the propellers were running in both videos. That's how quiet they are 😎 /s
