I can almost parse this, if it weren’t for “should”. (Edit: ah, “sound” makes sense, duh)

There is no medium for sound waves to propagate in outer space. Hence, if you were able to expel air from your lungs in such a way that would produce a “scream” in our atmosphere, there’s nowhere for that scream to go so nobody could hear it. An electronic device needs that medium as well to receive the sound waves and transform them into electric signals.

Edit: but of course, if “in space” means “on a spaceship”, there’s a high likelihood of an atmosphere to transport the soundwaves through that ship.
