Waves transfer inertia rather than matter. It's the same thing that happens when one pool ball hits another - the first pool ball stops while the second pool ball starts moving - except in this case it's billions upon billions of molecules of water (or air, if you're talking about sound waves) pushing against each other. so, when you shout 'Hai!' in good aikido fashion, your lungs contract, forcing air out of your mouth. that air uses up its energy compressing the air that's already around you, and that (newly compressed) air decompresses, pushing against the air a little farther away, which compresses and pushes against air a little bit farther than that, and so on. the original air pushed out of your lungs might travel a couple of feet, but the compression wave it creates can be transferred from molecule to molecule for a very long distance.
