You've also seen them project video images. Moreover who knows what the byakugan sees? It's supposed to have the greatest perception of the great eye techniques. Let's not forget that they have satellite stations, computers, television, video tapes, cameras, and batteries. Neji knowing about the speed of sound is perfectly plausible.
