So sound, which you must remember is an english, human word--is specific to us, not the universe. Air waves from moving objects are not.
Critters in the forest can hear the tree fall, and we can observe that using scientific instruments.

Sound is a very real physical phenomenon which I could prove to any alien species, just as I can prove it to you.

Maybe you would call it "air waves hitting an eardrum" but I can prove both the air waves, the ear drum, and the electrical activity in the brain, and prove that there is an intelligent comprehension of that data.

You've given a bad example.
