Sonic boom

A sonic boom is a loud, explosive sound created by shock waves when an object exceeds the speed of sound. It's caused by the compression of air as the object moves, creating a pressure difference that results in a powerful release of energy, perceived as a loud boom. The sound resembles an explosion or thunderclap due to the rapid and intense nature of the shock waves reaching the ear.
