A sonic boom is a loud sound produced when an object, such as an aircraft, travels through the air faster than the speed of sound. When an object moves at supersonic speed (Mach number greater than 1), it creates shock waves as it compresses the air ahead of it. These shock waves propagate outwards and reach the listener's ears as a 'boom'.
Sonic boom is produced when a source of sound travels at a speed :
