It would probably do well to have music, because it's just empty-sounding without it. I often hate it when they leave scenes silent that had music composed for them--was this one of those?
If those bombs are supposed to be sound waves, then that doesn't make any sense. No air in space to carry the sound waves . . . Sure the movies have sound, but that's just for the viewers pleasure; you can safely assume the characters aren't actually experiencing any sounds generated from outside their ships.
