A sonic boom sound vs explosion sound

sonic boom??

A sonic boom sounds much like an explosion correct? Explain the similarity between the two??

 

[LURCH]

The similarity between the two depends largely on the type of explosive being used. A Bick lighter or aerosol can cooking off in a fire makes a rumbling kind of noise, while high explosives such as plastique, have a much more staccato "crack." This is because high explosives, by definition, employ a reaction that expands faster than the speed of sound.

It is this quality that makes a sonic boom sound similar to a blast from high explosives. Each is a compression wave caused by air trying to move faster than the speed of sound.
