because when something goes so fast the air does not have time to move out of the way, so it makes a sound...like shooting a gun...thats what you hear the boom from.
a sonic boom
Sonic booms happen in pairs when an object producing the boom passes overhead twice: once when the object approaches the observer at supersonic speeds, and again when it moves away from the observer. Consequently, an initial boom is followed by a secondary boom.
I heard a huge sonic boom when the shuttle landed.
A sonic boom occurs when an object travels at or above the speed of sound (around 767 mph or 1,235 km/h). The exact speed can vary slightly depending on factors like air temperature and pressure.
for a sonic boom to occur, the object (usually a airplane)must travel supersonic or faster than the speed of sound(about 340 meters per second). The sonic boom continues as long as the object is supersonic. More info see http://en.wikipedia.org/wiki/Sonic_boom.
