On the implementation of the sound in the game (Battlefield 1)

I do not remember how it was in the last battle, but in the Unity notice periodically: before death (not headshots) only hear ONE shot from a pistol for example. Ie was clearly a series, but the game gives to hear only one.
Bug or on purpose, so as not to overload the ears of the continuous crash?

Or you can, had no such problem?
