What happens when you break the sound barrier?

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.

At what speed is the sound barrier broken?

The moment an aircraft's speed exceeds the speed of sound, it is said to have broken the sound barrier. At what speed do you break the sound barrier? The speed at which you break the sound barrier depends on many conditions, including weather and altitude. It's approximately 770 mph or 1,239 kmh at sea level.
