May be off topic, and I want to say it here. Yes, you can't get any emotional audio information without a sound, sound is a translation of that audio info into emotions... But, pure audio info can travel with radio waves free, bringing stories what's going on between molecules, between people, and even from beyond our normally perceived reality. Those very low to extremely low radio waves can deliver those thoughts, and if you can translate them to sound, you may hear them, for instance of an old friend saying no worries he's alright. That's all. :)

Can't be naturally heard though.
This video explains what we would hear with our own ears if there wasn't a vaccum of space, but different gases instead (that each one of them propagate the sound at different speeds)
Yeah true, naturally, and if you are healthy, you may catch those only with some old enough recorder without any filters. Your vid is really interesting, still watching now, I just added some info in case you want to know. :)
