One time, during a space walk, I cut a big fart to see if I could hear it in the vacuum of outer space. Yeah, I really didn't think that one through beforehand...

In the new experiment, researchers transmitted, or "tunneled," sound waves across a vacuum between two zinc oxide crystals by transforming the vibrating waves into ripples within an electric field between the objects.

So no, you cannot transmit sound in a vacuum. I wish scientific publications would stay away from clickbait titles.
