Detailed explanation-1: -When a sound source moves faster than the speed of sound, a shock wave is produced as the sound waves interfere. A sonic boom is the intense sound that occurs as the shock wave moves along the ground.
Detailed explanation-2: -An aircraft traveling through the atmosphere continuously produces air-pressure waves similar to the water waves caused by a ship’s bow. When the aircraft exceeds the speed of sound, these pressure waves combine and form shock waves which travel forward from the generation or “release” point.
Detailed explanation-3: -As this wave-front passes an individual, the sudden pressure differential or change in pressure creates the “sonic boom” that we hear. Anything exceeding the speed of sound creates a “sonic boom", not just airplanes. An airplane, a bullet, or the tip of a bullwhip can create this effect; they all produce a crack.
Detailed explanation-4: -There are several factors that can influence sonic booms–weight, size, and shape of the aircraft or vehicle, plus its altitude, attitude and flight path, and weather or atmospheric conditions.
