Sound Barrier
Sound Barrier is a common term referring to the unusual amounts of drag in a fluid when an object approaches the speed of sound, which is about 1125 ft/s or 767 mph in dry air. First observed during World War II, the sound barrier doesn't exist as a physical limitation but rather represents the difficulty at which objects near the speed of sound experience when trying to accelerate further. The point at which the object does exceed this threshold, a shock wave is produced. The faster the object, the more conical the shock wave.
Sonic Boom
The sonic boom is heard once the object passes the speed of sound. It is the result of all the compressible regions or high pressure regions in a wave front reaching you all at the same time instead of the usual delayed observed in the Doppler effect.
