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.
Jums jāsaprot, ka lodes pārvietojas daudz ātrāk nekā skaņa, tāpēc, ja kāds uz jums šauj no dažu simtu metru attāluma, lode paiet garām  — nu vai, protams, trāpa — aptuveni pussekundi, pirms skaņa to panāk.
