Sonic Booms and Supersonic Flight

A sonic boom occurs when an object moves through a medium at the speed of sound in that medium. Due to the Doppler Effect, the sound waves will stack on top of each other, adding together (constructive interference) to create a sound wave with a very large amplitude.

If a jet plane is traveling faster than Mach 1.0, why can people in the front of the plane still hear the sound of the engines in the back of the plane?
