1 Even though the name of the archangel is not mentioned in 1 Thessalonians, Jude 9 makes reference to Michael the archangel.. 2  Even Billy Graham wrote in his book  Angels: Godâs Secret Agents , He [Michael] must stand alone, because the Bible never speaks of archangels, only the archangel..
Sonic booms generate enormous amounts of sound energy, sounding much like an explosion; typically the shock front may approach 100 megawatts per square meter, and may exceed 200 decibels. 10 log (100 x 10^(6)/ 10^(-12)) = 200 dB.
Pressure, build up by the shock wave, is then released sharply. That is heard as the sonic boom. The change in air pressure associated with a sonic boom is only a few pounds per square foot - about the same pressure change experienced riding an elevator down two or three floors. It is the rate of change, the sudden onset of the pressure change, that makes the sonic boom audible, NASA says.
