You have to understand about bullets that they go a lot faster than sound, so if someone shoots at you from a few hundred meters, the bullet goes by you, or hits you obviously, half a second or so before the sound catches up to it.
É preciso saber que as balas andam mais depressa do que o som. Se alguém disparar contra nós de algumas centenas de metros, a bala entra em nós, ou atinge-nos meio segundo antes de ouvirmos o som.
