Did you know?

A sonic boom is an explosive sound created by a shock wave formed at the nose of an aircraft. In 1947 a plane piloted by Chuck Yeager burst the "sound barrier" and created the first sonic boom. In the decades afterward sonic booms became a familiar sound to Americans. (Because of steps that were eventually taken, sonic booms are rarely heard anymore.) Today sonic is often used by ambitious rock musicians to describe their experimental sounds.
