THE ROAD (CORMAC MCCARTHY), HEARING IN THE BRAIN, SUBSONIC AND SUPERSONIC BULLETS

You aint got but two shells. Maybe just one. And they’ll hear the shot.
Yes they will. But you wont.
How do you figure that?
Because the bullet travels faster than sound. It will be in your brain before you can hear it. To hear it you will need a frontal lobe and things with names like colliculus and temporal gyrus and you wont have them anymore. They’ll just be soup.


I think he is right. The speed of sound is about 340 m/s. So if you are about 700 metres away from a shooting gun, you should heard the shot two seconds later. The bullet reaches you before its sound, if it´s supersonic. This is something that sound technicians must keep in mind.This video explains it very well:
