This is because the supersonic bullet is traveling faster than the speed of sound, which produces a cracking sound when it breaks the sound barrier. Since subsonic bullets travel slower than the speed of sound, they do not break the sound barrier and do not produce a.
Breaking the sound barrier requires exceeding the speed of sound, which is approximately 761 miles per hour at seal level when the air temperature is 59 degrees Fahrenheit. As the temperature decreases, the speed of sound also decreases. When bullets are fired from a machine gun, they travel at a speed greater than the speed of sound.
