Sonic Booms

The Science of the Boom

When Guile's fist passes through the air, it creates a series of pressure waves in front of it and behind it, similar to the bow and stern waves created by a boat. These waves travel at the speed of sound, and as the speed of the fist increases, the waves are forced together, or compressed, because they cannot "get out of the way" of each other, eventually merging into a single shock wave at the speed of sound. This critical speed is known as Mach 1 and is approximately 1,225 km/h (761 mph) at sea level and 20 °C (68 °F). In a smooth swing, the shock wave starts at the knuckles of his fist and ends at the shoulder. Because directions around the fist's direction of travel are equivalent, the shock forms a Sonic Boom with the fist at its tip. The half-angle (between direction of swing and the shock wave) α is given by

is the fist's Mach number. So the faster it goes, the faster the Sonic Boom.

The Copyright of the Boom

Over the years as Guile and his Sonic Booms became ever more popular, ripoffs have appeared almost everywhere, including in

Magic: The Gathering

cubeecraft,

fragrant incense products,

music albums,

bad films,

evil cloning experiments,

and nature.

As you can see, Guile is not amused.

Be smart. Be original. Use only the real thing.

The Technique of the Boom

Hold the joystick in the away position for 2 full seconds (count slowly), then in one fluid motion, switch the joystick to forward and press any punch button (The speed of the Sonic Boom is determined by the strength of the punch; weaker punches will produce slower sonic booms)


An alternative method is to swing your arms really hard as shown.

When your fists exceed the speed of Mach 1, a Sonic Boom will be produced.



If both methods don't work for you,
