Okay I've got one for you:
What causes thunder? The sudden expansion of gas from being heated by lightning. Right, so let's keep that in mind and visualize a Klingon vaporizing someone. There should be a huge thunderclap when all the matter that is condensed in a person is converted suddenly into vapor. At least some rushing wind. How about when it's done on a space ship? When someone is vaporized, all of a sudden, the ship should overpressure from all the extra gas. How 'bout them apples?
