This analysis explains the distinct 'crack' and 'bang' sounds heard during gunfire. The 'crack' is the supersonic shockwave from the bullet exceeding the speed of sound, while the 'bang' is the muzzle blast. The absence of the double crack indicates the shot was either very close or the bullet was subsonic.

This guide demonstrates the audible difference between supersonic and subsonic 9mm ammunition when used with a suppressor. It highlights how suppressors work by slowing gas expansion and explains that subsonic rounds avoid the 'crack' of breaking the sound barrier. The demonstration involves firing a mixed magazine through a suppressed handgun in an indoor range setting.
