- Clesser than the speed of sound.
- Dequal to the speed of sound.
Explanation
A sonic boom is the shock wave produced when a source moves through air faster than the speed of sound (Mach number greater than 1), as with supersonic aircraft. The pressure waves pile up into a cone-shaped shock front that is heard as a loud boom. A source moving at or below the speed of sound does not generate this effect.
