Of course in space there isn’t any air, let alone water or wood, for the sound waves to travel through. So if you shouted in space, and you weren’t wearing a helmet, your vocal cords wouldn’t have anything to make pressure waves in, and so wouldn’t make a normal shouting sound. If you shouted inside your space helmet, you would hear a proper shout, because the sound waves would have some air to travel through before they reached your ear. But here’s the weird bit. Other astronauts that happened to be with you wouldn’t hear a thing, because there wouldn’t be any air to carry your shout to them.
